<toc>
<sect>Introduction
<p>
sqlmap is an open source penetration testing tool that automates the
process of detecting and exploiting SQL injection flaws and taking over of
back-end database servers.
It comes with a broad range of features lasting from database
fingerprinting, over data fetching from the database, to accessing the
underlying file system and executing commands on the operating system via
out-of-band connections.
<sect1>Requirements
<p>
sqlmap is developed in <htmlurl url="http://www.python.org" name="Python">,
a dynamic object-oriented interpreted programming language.
This makes the tool independent from the operating system. It only
requires the Python interpreter version equal or above to <bf>2.5</bf>.
The interpreter is freely downloadable from its
<htmlurl url="http://python.org/download/" name="official site">.
To make it even easier, many GNU/Linux distributions come out of the box
with Python interpreter installed and other Unices and Mac OSX too provide
it packaged in their formats and ready to be installed.
Windows users can download and install the Python setup-ready installer
for x86, AMD64 and Itanium too.
sqlmap relies on the <htmlurl url="http://metasploit.com/framework/"
name="Metasploit Framework"> for some of its post-exploitation takeover
features. You need to grab a copy of it from the
<htmlurl url="http://metasploit.com/framework/download/" name="download">
page. The required version is <bf>3.4</bf> or above.
If you plan to attack a web application behind NTLM authentication or use
the sqlmap update functionality you need to install respectively
<htmlurl url="http://code.google.com/p/python-ntlm/" name="python-ntlm">
and <htmlurl url="http://pysvn.tigris.org/" name="python-svn"> libraries.
Optionally, if you are running sqlmap on Windows, you may wish to install
<htmlurl url="http://ipython.scipy.org/moin/PyReadline/Intro" name="PyReadline">
library to be able to take advantage of the sqlmap TAB completion and
history support functionalities in the SQL shell and OS shell.
Note that these functionalities are available natively by Python standard
<htmlurl url="http://docs.python.org/library/readline.html" name="readline">
library on other operating systems.
You can also choose to install <htmlurl url="http://psyco.sourceforge.net/"
name="Psyco"> library to speed up the sqlmap algorithmic operations.
<sect1>Scenario
<p>
Let's say that you are auditing a web application and found a web page
that accepts dynamic user-provided values on <tt>GET</tt> or <tt>POST</tt>
parameters or HTTP <tt>Cookie</tt> values or HTTP <tt>User-Agent</tt>
header value.
You now want to test if these are affected by a SQL injection
vulnerability, and if so, exploit them to retrieve as much information as
possible out of the web application's back-end database management system
or even be able to access the underlying operating system.
Consider that the target url is:
<tscreen><tt>http://172.16.213.131/sqlmap/mysql/get_int.php?id=1</tt></tscreen>
Assume that:
<tscreen><tt>http://172.16.213.131/sqlmap/mysql/get_int.php?id=1+AND+1=1</tt></tscreen>
is the same page as the original one and:
<tscreen><tt>http://172.16.213.131/sqlmap/mysql/get_int.php?id=1+AND+1=2</tt></tscreen>
differs from the original one, it means that you are in front of a SQL
injection vulnerability in the <tt>id</tt> <tt>GET</tt> parameter of the
<tt>index.php</tt> web application page which means that no IDS/IPS, no
web application firewall, no parameters' value sanitization is performed
on the server-side.
This is a quite common flaw in dynamic content web applications and it
does not depend upon the back-end database management system nor on the web
application programming language: it is a programmer code's security flaw.
The <htmlurl url="http://www.owasp.org" name="Open Web Application Security Project">
rated on 2010 in their <htmlurl url="http://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project"
name="OWASP Top Ten"> survey this vulnerability as the <htmlurl
url="http://www.owasp.org/images/0/0f/OWASP_T10_-_2010_rc1.pdf" name="most
common"> and important web application vulnerability along with other
injection flaws.
Back to the scenario, probably the SQL <tt>SELECT</tt> statement into
<tt>get_int.php</tt> has a syntax similar to the following SQL query, in
pseudo PHP code:
<tscreen><tt>
$query = "SELECT &#91;column(s) name&#93; FROM &#91;table name&#93; WHERE id=" . $_REQUEST['id'];
</tt></tscreen>
As you can see, appending any other syntatically valid SQL condition after
a value for <tt>id</tt> such condition will take place when the web
application passes the query to the back-end database management system
that executes it, that is why the condition <tt>id=1 AND 1=1</tt> is valid
(<em>True</em>) and returns the same page as the original one, with the
same content and without showing any SQL error message.
Moreover, in this simple and easy to inject scenario it would be also
possible to append, not just one or more valid SQL condition(s), but also
stacked SQL queries, for instance something like <tt>[...]&amp;id=1;
ANOTHER SQL QUERY#</tt> if the web application technology supports
<em>stacked queries</em>, also known as <em>multiple statements</em>.
Now that you found this SQL injection vulnerable parameter, you can
exploit it by manipulating the <tt>id</tt> parameter value in the HTTP
request.
There exist many <htmlurl url="http://delicious.com/inquis/sqlinjection" name="resources">
on the Net explaining in depth how to prevent, how to detect and how to
exploit SQL injection vulnerabilities in web application and it is
recommended to read them if you are not familiar with the issue before
going ahead with sqlmap.
Passing the original address, <tt>http://172.16.213.131/sqlmap/mysql/get_int.php?id=1</tt>
to sqlmap, the tool will automatically:
<itemize>
<item>Identify the vulnerable parameter(s) (<tt>id</tt> in this scenario);
<item>Depending on the user's options, fingerprint, enumerate, takeover
the database server.
</itemize>
<sect1>Techniques
<p>
sqlmap implements three techniques to exploit a SQL injection
vulnerability:
<itemize>
<item><bf>Inferential blind SQL injection</bf>, also known as <bf>boolean
based blind SQL injection</bf>: sqlmap appends to the affected parameter in
the HTTP request, a syntatically valid SQL statement string containing a
<tt>SELECT</tt> sub-statement, or any other SQL statement whose the user
want to retrieve the output.
For each HTTP response, by making a comparison based upon HTML page
content hashes, or string matches, with the original request, the tool
determines the output value of the statement character by character.
The bisection algorithm implemented in sqlmap to perform this technique
is able to fetch each output character with at maximum seven HTTP
requests.
This is sqlmap default SQL injection technique.
<item><bf>UNION query (inband) SQL injection</bf>, also known as <bf>full
UNION query SQL injection</bf>: sqlmap appends to the affected parameter
in the HTTP request, a syntatically valid SQL statement string starting
with a <tt>UNION ALL SELECT</tt>. This techique is useful if the web
application page passes the output of the <tt>SELECT</tt> statement to a
<tt>for</tt> cycle, or similar, so that each line of the query output is
printed on the page content.
sqlmap is also able to exploit <bf>partial (single entry) UNION query SQL
injection</bf> vulnerabilities which occur when the output of the statement
is not cycled in a for construct whereas only the first entry output is
displayed.
This technique is much faster if the target url is affected by because
in a single HTTP response it returns the whole query output or a entry
per each response within the page content.
This SQL injection technique is an alternative to the first one.
<item><bf>Batched (stacked) queries support</bf>, also known as <bf>multiple
statements support</bf>: sqlmap tests if the web application supports
stacked queries then, in case it does support, it appends to the affected
parameter in the HTTP request, a semi-colon (<tt>;</tt>) followed by the
SQL statement to be executed. This technique is useful to run SQL
statements other than <tt>SELECT</tt> like, for instance, <em>data
definition</em> or <em>data manipulation</em> statements possibly leading
to file system read and write access and operating system command
execution depending on the underlying back-end database management system
and the session user privileges.

</itemize>
<sect>Features
<p>
Features implemented in sqlmap include:
<sect1>Generic features
<p>
<itemize>
<item>Full support for <bf>MySQL</bf>, <bf>Oracle</bf>, <bf>PostgreSQL</bf>
and <bf>Microsoft SQL Server</bf> back-end database management systems.
Besides these four database management systems software, sqlmap can also
identify Microsoft Access, DB2, Informix, Sybase and Interbase.
<item>Full support for three SQL injection techniques: <bf> inferential
blind SQL injection</bf>, <bf>UNION query (inband) SQL injection</bf> and
<bf>batched queries support</bf>. sqlmap can also test for <bf>time based
blind SQL injection</bf>.
<item>It is possible to provide a single target URL, get the list of
targets from <htmlurl url="http://portswigger.net/suite/" name="Burp proxy">
requests log file or
<htmlurl url="http://www.owasp.org/index.php/Category:OWASP_WebScarab_Project"
name="WebScarab proxy"> <tt>conversations/</tt> folder, get the whole HTTP
request from a text file or get the list of targets by providing sqlmap
with a Google dork which queries <htmlurl url="http://www.google.com"
name="Google"> search engine and parses its results page. You can also
define a regular-expression based scope that is used to identify which of
the parsed addresses to test.
<item>Automatically tests all provided <bf>GET</bf> parameters,
<bf>POST</bf> parameters, HTTP <bf>Cookie</bf> header values and HTTP
<bf>User-Agent</bf> header value to find the dynamic ones, which means
those that vary the HTTP response page content.
On the dynamic ones sqlmap automatically tests and detects the ones
affected by SQL injection. Each dynamic parameter is tested for
<em>numeric</em>, <em>single quoted string</em>, <em>double quoted
string</em> and all of these three data-types with zero to two parenthesis
to correctly detect which is the <tt>SELECT</tt> statement syntax to
perform further injections with. It is also possible to specify the only
parameter(s) that you want to perform tests and use for injection on.
<item>Option to specify the <bf>maximum number of concurrent HTTP
requests</bf> to speed up the inferential blind SQL injection algorithms
(multi-threading). It is also possible to specify the number of seconds to
wait between each HTTP request.
<item><bf>HTTP <tt>Cookie</tt> header</bf> string support, useful when the
web application requires authentication based upon cookies and you have
such data or in case you just want to test for and exploit SQL injection
on such header. You can also specify to always URL-encode the Cookie
header.
<item>Automatically handle <bf>HTTP <tt>Set-Cookie</tt> header</bf> from
the application, re-establishing of the session if it expires. Test and
exploit on these values is supported too. You can also force to ignore any
<tt>Set-Cookie</tt> header.
<item><bf>HTTP Basic, Digest, NTLM and Certificate authentications</bf>
support.
<item><bf>Anonymous HTTP proxy</bf> support to pass by the requests to the
target application that works also with HTTPS requests.
<item>Options to fake the <bf>HTTP <tt>Referer</tt> header</bf> value and
the <bf>HTTP <tt>User-Agent</tt> header</bf> value specified by user or
randomly selected from a text file.
<item>Support to increase the <bf>verbosity level of output messages</bf>:
there exist <bf>six levels</bf>. The default level is <bf>1</bf> in which
information, warnings, errors and tracebacks (if any occur) will be shown.
<item>Granularity in the user's options.
<item><bf>Estimated time of arrival</bf> support for each query, updated
in real time while fetching the information to give to the user an
overview on how long it will take to retrieve the output.
<item>Automatic support to save the session (queries and their output,
even if partially retrieved) in real time while fetching the data on a
text file and <bf>resume the injection from this file in a second
time</bf>.
<item>Support to read options from a configuration INI file rather than
specify each time all of the options on the command line. Support also to
save command line options on a configuration INI file.
<item>Option to update sqlmap as a whole to the latest development version
from the Subversion repository.
<item>Integration with other IT security open source projects,
<htmlurl url="http://metasploit.com/framework/" name="Metasploit"> and <htmlurl
url="http://w3af.sourceforge.net/" name="w3af">.
</itemize>
<sect1>Fingerprint and enumeration features
<p>
<itemize>
<item><bf>Extensive back-end database software version and underlying
operating system fingerprint</bf> based upon
<htmlurl url="http://bernardodamele.blogspot.com/2007/06/database-management-system-fingerprint.html" name="inband error messages">,
<htmlurl url="http://bernardodamele.blogspot.com/2007/06/database-management-system-fingerprint.html" name="banner parsing">,
<htmlurl url="http://bernardodamele.blogspot.com/2007/07/more-on-database-management-system.html" name="functions output comparison"> and
<htmlurl url="http://bernardodamele.blogspot.com/2007/07/more-on-database-management-system.html" name="specific features">
such as MySQL comment injection. It is also possible to force the back-end
database management system name if you already know it.
<item>Basic web server software and web application technology fingerprint.
<item>Support to retrieve the DBMS <bf>banner</bf>, <bf>session user</bf>
and <bf>current database</bf> information. The tool can also check if the
session user is a database administrator (DBA).
<item>Support to enumerate <bf>database users</bf>, <bf>users' password
hashes</bf>, <bf>users' privileges</bf>, <bf>databases</bf>,
<bf>tables</bf> and <bf>columns</bf>.
<item>Support to <bf>dump database tables</bf> as a whole or a range of
entries as per user's choice. The user can also choose to dump only
specific column(s).
<item>Support to automatically dump <bf>all</bf> databases' schemas and
entries. It is possibly to exclude from the dump the system databases.
<item>Support to enumerate and dump <bf>all databases' tables containing user
provided column(s)</bf>. Useful to identify for instance tables containing
custom application credentials.
<item>Support to <bf>run custom SQL statement(s)</bf> as in an interactive
SQL client connecting to the back-end database. sqlmap automatically
dissects the provided statement, determines which technique to use to
inject it and how to pack the SQL payload accordingly.
</itemize>
<sect1>Takeover features
<p>
Some of these techniques are detailed in the white paper
<htmlurl url="http://sqlmap.sourceforge.net/doc/BlackHat-Europe-09-Damele-A-G-Advanced-SQL-injection-whitepaper.pdf"
name="Advanced SQL injection to operating system full control"> and in the
slide deck <htmlurl url="http://www.slideshare.net/inquis/expanding-the-control-over-the-operating-system-from-the-database"
name="Expanding the control over the operating system from the database">.
<itemize>
<item>Support to <bf>inject custom user-defined functions</bf>: the user
can compile shared object then use sqlmap to create within the back-end
DBMS user-defined functions out of the compiled shared object file. These
UDFs can then be executed, and optionally removed, via sqlmap too.
<item>Support to <bf>read and upload any file</bf> from the database
server underlying file system when the database software is MySQL,
PostgreSQL or Microsoft SQL Server.
<item>Support to <bf>execute arbitrary commands and retrieve their
standard output</bf> on the database server underlying operating system
when the database software is MySQL, PostgreSQL or Microsoft SQL Server.
<itemize>
<item>On MySQL and PostgreSQL via user-defined function injection and
execution.
<item>On Microsoft SQL Server via <tt>xp_cmdshell()</tt> stored procedure.
Also, the stored procedure is re-enabled if disabled or created from
scratch if removed.
</itemize>
<item>Support to <bf>establish an out-of-band stateful TCP connection
between the user machine and the database server</bf> underlying operating
system. This channel can be an interactive command prompt, a Meterpreter
session or a graphical user interface (VNC) session as per user's choice.
sqlmap relies on Metasploit to create the shellcode and implements four
different techniques to execute it on the database server. These
techniques are:
<itemize>
<item>Database <bf>in-memory execution of the Metasploit's shellcode</bf>
via sqlmap own user-defined function <tt>sys_bineval()</tt>. Supported on
MySQL and PostgreSQL.
<item>Upload and execution of a Metasploit's <bf>stand-alone payload
stager</bf> via sqlmap own user-defined function <tt>sys_exec()</tt> on
MySQL and PostgreSQL or via <tt>xp_cmdshell()</tt> on Microsoft SQL
Server.
<item>Execution of Metasploit's shellcode by performing a <bf>SMB
reflection attack</bf> (<htmlurl
url="http://www.microsoft.com/technet/security/Bulletin/MS08-068.mspx"
name="MS08-068">) with a UNC path request from the database server to
the user's machine where the Metasploit <tt>smb_relay</tt> server exploit
runs.
<item>Database in-memory execution of the Metasploit's shellcode by
exploiting <bf>Microsoft SQL Server 2000 and 2005
<tt>sp_replwritetovarbin</tt> stored procedure heap-based buffer
overflow</bf> (<htmlurl
url="http://www.microsoft.com/technet/security/bulletin/ms09-004.mspx"
name="MS09-004">) with automatic DEP bypass.
</itemize>
<item>Support for <bf>database process' user privilege escalation</bf> via
Metasploit's <tt>getsystem</tt> command which include, among others,
the <htmlurl
url="http://archives.neohapsis.com/archives/fulldisclosure/2010-01/0346.html"
name="kitrap0d"> technique (<htmlurl
url="http://www.microsoft.com/technet/security/bulletin/ms10-015.mspx"
name="MS10-015">) or via <htmlurl
url="http://labs.mwrinfosecurity.com/files/Publications/mwri_security-implications-of-windows-access-tokens_2008-04-14.pdf"
name="Windows Access Tokens insecure design"> by using Meterpreter's
<tt>incognito</tt> extension.
<item>Support to access (read/add/delete) Windows registry hives.
</itemize>
<sect>Download and update
<p>
sqlmap can be downloaded from its
<htmlurl url="http://sourceforge.net/projects/sqlmap/files/" name="SourceForge File List page">.
It is available in various formats:
<itemize>
<item><htmlurl url="http://downloads.sourceforge.net/sqlmap/sqlmap-0.8.tar.gz"
name="Source gzip compressed"> operating system independent.
<item><htmlurl url="http://downloads.sourceforge.net/sqlmap/sqlmap-0.8.tar.bz2"
name="Source bzip2 compressed"> operating system independent.
<item><htmlurl url="http://downloads.sourceforge.net/sqlmap/sqlmap-0.8.zip"
name="Source zip compressed"> operating system independent.
<item><htmlurl url="http://downloads.sourceforge.net/sqlmap/sqlmap_0.8-1_all.deb"
name="DEB binary package"> architecture independent for Debian and any
other Debian derivated GNU/Linux distribution.
<item><htmlurl url="http://downloads.sourceforge.net/sqlmap/sqlmap-0.8-1.noarch.rpm"
name="RPM binary package"> architecture independent for Fedora and any
other operating system that can install RPM packages.
<item><htmlurl url="http://downloads.sourceforge.net/sqlmap/sqlmap-0.8_exe.zip"
name="Portable executable for Windows"> that <bf>does not require the Python
interpreter</bf> to be installed on the operating system.
</itemize>
<p>
You can also checkout the latest development version from the sqlmap
<htmlurl url="https://svn.sqlmap.org/sqlmap/trunk/sqlmap/" name="Subversion">
repository:
<tscreen><verb>
$ svn checkout https://svn.sqlmap.org/sqlmap/trunk/sqlmap sqlmap-dev
</verb></tscreen>
<p>
If you download a source package (gzip, bzip2 or zip) or sqlmap from the
Subversion repository, you can update it to the latest development version
anytime by running:
<tscreen><verb>
$ python sqlmap.py --update
</verb></tscreen>
Or:
<tscreen><verb>
$ svn update
</verb></tscreen>
<p>
Viceversa if you download a binary package (deb, rpm or exe), the
update feature is disabled.
<p>
There are some differences between the packages:
<itemize>
<item>The source packages (gzip, bzip2 and zip) have all features. They
contains the working copy from the Subversion repository updated at the
time the sqlmap new version has been released.
<item>The Debian and Red Hat installation packages (deb and rpm) are
compliant with the Linux distributions' packaging guidelines. This implies
that they do not support the update features and do not include UPX (used
to pack the Metasploit payload stager in some cases, see below).
<item>The Windows binary package (exe) can't update itself and does not
support the takeover out-of-band features because they rely on
Metasploit's <tt>msfcli</tt> which is not available for Windows.
</itemize>
<p>
It is therefore recommended to download any of the source packages and run
it either from a shell like Bash on Unix and Mac OSX or from Cygwin on
Windows.

<sect2>Load options from a configuration INI file
<p>
Option: <tt>-c</tt>
<p>
It is possible to pass user's options from a configuration INI file, an

<p>
Example usage:
<tscreen><verb>

<p>
Note that if you also provide other options from command line, those are
evaluated when running sqlmap and overwrite the same options, if set, in
the provided configuration file.
<sect1>Request
<p>
These options can be used to specify how to connect to the target
application.
<sect2>HTTP method: <tt>GET</tt> or <tt>POST</tt>
<p>
Options: <tt>-</tt><tt>-method</tt> and <tt>-</tt><tt>-data</tt>
<p>
By default the HTTP method used to perform HTTP requests is <tt>GET</tt>,
but you can change it to <tt>POST</tt> and provide the data to be sent
through <tt>POST</tt> request. Such data, being those parameters, are
tested for SQL injection like the <tt>GET</tt> parameters.

<sect2>HTTP <tt>Cookie</tt> header
<p>
Options: <tt>-</tt><tt>-cookie</tt>, <tt>-</tt><tt>-cookie-urlencode</tt> and <tt>-</tt><tt>-drop-set-cookie</tt>
<p>
This feature can be useful in two scenarios:
<itemize>
<item>The web application requires authentication based upon cookies and
you have such data.
<item>You want to test for and exploit SQL injection on such header
values.
</itemize>
<p>
The steps to go through in the second scenario are the following:
<itemize>
<item>On Firefox web browser login on the web authentication form while
dumping URL requests with <htmlurl url="http://tamperdata.mozdev.org/"
name="TamperData"> browser's extension.
<item>In the horizontal box of the extension select your authentication
transaction then in the left box on the bottom click with the right button
on the <tt>Cookie</tt> value, then click on <tt>Copy</tt> to save its
value to the clipboard.
<item>Go back to your shell and run sqlmap.
</itemize>
<p>
Example on a <bf>Microsoft SQL Server 2000 Service Pack 0</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/mssql/cookie_int.php" --cookie \

<p>
Note that the HTTP <tt>Cookie</tt> header values are usually separated by
a <tt>;</tt> character, <bf>not</bf> by an <tt>&amp;</tt>.
<p>
If the web application at first HTTP response has a <tt>Set-Cookie</tt>
header, sqlmap will automatically use it's value in all further HTTP
requests as the <tt>Cookie</tt> header. sqlmap will also automatically
test that value for SQL injection, except if you run it with
<tt>--drop-set-cookie</tt> option.
<p>

<p>
If you provide an HTTP <tt>Cookie</tt> header value and the target URL
sends an HTTP <tt>Set-Cookie</tt> header, sqlmap asks you which one to use
in the following HTTP requests.
<p>
Example on a <bf>Microsoft SQL Server 2000 Service Pack 0</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.128/sqlmap/get_str.asp?name=luther" --cookie "id=1"

own Cookie within the HTTP Set-Cookie header. Do you want to continue using the HTTP cookie
values that you provided? [Y/n]
</verb></tscreen>
<p>
sqlmap by default doesn't URL encode generated cookie injections, but you can force it by
using the <tt>-</tt><tt>-cookie-urlencode</tt> flag. Cookie content encoding is not declared
by standard in any way, so it's solely the matter of web application's behaviour.
<sect2>HTTP <tt>User-Agent</tt> header
<p>
Options: <tt>-</tt><tt>-user-agent</tt> and <tt>-a</tt>

<p>
Note that the HTTP <tt>User-Agent</tt> header is tested against SQL
injection also if you do not overwrite the default sqlmap HTTP
<tt>User-Agent</tt> header value.
<p>
Some sites perform a server-side check on the HTTP <tt>User-Agent</tt>
header value and fail the HTTP response if a valid <tt>User-Agent</tt> is
not provided, its value is not expected or its value is blocked by a web
application firewall or similar intrusion prevention system. In this case
sqlmap will show you a message as follows:

<sect2>Extra HTTP headers
<p>
Option: <tt>-</tt><tt>-headers</tt>
<p>
It is possible to provide extra HTTP headers by providing <tt>-</tt><tt>-headers</tt>
options. Each header must be separated by a newline and it's much easier
to provide them from the configuration INI file. Have a look at the sample
<tt>sqlmap.conf</tt> file.

<p>
Options: <tt>-</tt><tt>-auth-type</tt> and <tt>-</tt><tt>-auth-cred</tt>

HTTP requests to the target application.
The three valid types are <tt>Basic</tt>, <tt>Digest</tt> and <tt>NTLM</tt>,

cert_file</tt>, where <tt>key_file</tt> should be the name of a PEM formatted file that
contains your private key, while <tt>cert_file</tt> should be the name for a PEM formatted
certificate chain file.

<sect2>HTTP proxy
<p>
Option: <tt>-</tt><tt>-proxy</tt> and <tt>-</tt><tt>-ignore-proxy</tt>
<p>
It is possible to provide an anonymous HTTP proxy address to pass by the
HTTP requests to the target URL. The syntax of HTTP proxy value is
<tt>http://url:port</tt>.
<p>
Example on a <bf>PostgreSQL 8.3.5</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" \

[hh:mm:37] [WARNING] the back-end DMBS is not Oracle
back-end DBMS: PostgreSQL
</verb></tscreen>
<p>
Instead of using a single anonymous HTTP proxy server to pass by, you can
configure a <htmlurl url="http://tor.eff.org" name="Tor client"> together
with <htmlurl url="http://www.privoxy.org" name="Privoxy"> on your machine
as explained on the <htmlurl url="http://tor.eff.org/docs/tor-doc-unix.html.en"
name="Tor client guide"> then run sqlmap as follows:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" \
--proxy "http://172.16.213.1:8118"
</verb></tscreen>
<p>
Note that <tt>8118</tt> is the default Privoxy port, adapt it to your
settings.
<p>
The option <tt>-</tt><tt>-ignore-proxy</tt> should be used in cases like
when you want to run sqlmap against the machine inside a local area
network skipping default usage of a system-wide set HTTP proxy server.
<sect2>Concurrent HTTP requests
<p>
Option: <tt>-</tt><tt>-threads</tt>
<p>
It is possible to specify the number of maximum concurrent HTTP requests
that sqlmap can start when it uses the blind SQL injection technique to
retrieve the query output.
This feature relies on the <htmlurl url="http://en.wikipedia.org/wiki/Multithreading"
name="multithreading"> concept and inherits both its pro and its cons.
<p>
Examples on a <bf>MySQL 5.0.67</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" -v 1 \
--current-user --threads 3

</verb></tscreen>
<p>
As you can see, sqlmap first calculates the length of the query output,
then starts three threads. Each thread is assigned to retrieve one
character of the query output. The thread then ends after up to seven
HTTP requests, the maximum requests to retrieve a query output character
with the blind SQL injection bisection algorithm implemented in sqlmap.
<p>
Note that the multithreading option is not needed if the target is affected
by an inband SQL injection vulnerability and the <tt>-</tt><tt>-union-use</tt>
option has been provided.

<p>
Option: <tt>-</tt><tt>-delay</tt>
<p>
It is possible to specify a number of seconds to wait between each HTTP
request. The valid value is a float, for instance 0.5 means half a second.
<sect2>Seconds to wait before timeout connection
<p>
Option: <tt>-</tt><tt>-timeout</tt>
<p>
It is possible to specify a number of seconds to wait before considering
the HTTP request timed out. The valid value is a float, for instance
10.5 means ten seconds and a half.
<sect2>Maximum number of retries when the HTTP connection timeouts
<p>
Option: <tt>-</tt><tt>-retries</tt>
<p>
It is possible to specify the maximum number of retries when the HTTP
connection timeouts. By default it retries up to three times.
<sect2>Filtering targets from provided proxy log using regular expression
<p>
Option: <tt>-</tt><tt>-scope</tt>
<p>
Rather than using all hosts parsed from provided logs with option
<tt>-l</tt>, in combination with this option you can specify valid
python regular expression to be used for filtering desired ones.
Example usage:
<tscreen><verb>
$ python sqlmap.py -l /tmp/webscarab.log/conversations/ --scope="(www)?\.target\.(com|net|org)"
</verb></tscreen>
<sect1>Injection
<p>
These options can be used to specify which parameters to test for, provide
custom injection payloads and how to parse and compare HTTP responses page
content when using the blind SQL injection technique.
<sect2>Testable parameter(s)
<p>
Option: <tt>-p</tt>
<p>
By default sqlmap tests all <tt>GET</tt> parameters, <tt>POST</tt>
parameters, HTTP <tt>Cookie</tt> header values and HTTP <tt>User-Agent</tt>
header value for dynamicity and SQL injection vulnerability, but it is
possible to manually specify the parameter(s) you want sqlmap to perform
tests on comma separeted in order to skip dynamicity tests and perform SQL
injection test and inject directly only against the provided parameter(s).
Example on a <bf>PostgreSQL 8.3.5</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" -v 1 \

<p>
Or, if you want to provide more than one parameter, for instance:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1&amp;cat=2" -v 1 \

<sect2>Force the database management system name
<p>
Option: <tt>-</tt><tt>-dbms</tt>
<p>
By default sqlmap automatically detects the web application's back-end
database management system.
At the moment, fully supported database management systems are:
<itemize>
<item>MySQL
<item>Oracle
<item>PostgreSQL
<item>Microsoft SQL Server
</itemize>
<p>
It is possible to force the DBMS name if you already know it so that sqlmap
will skip the fingerprint with an exception for MySQL and Microsoft SQL
Server to only identify the version.
To avoid also this check you can provide instead <tt>MySQL &lt;version&gt;</tt> or
<tt>Microsoft SQL Server &lt;version&gt;</tt>, where &lt;version&gt; is a valid version for
the DBMS; for instance <tt>5.0</tt> for MySQL and <tt>2005</tt> for
Microsoft SQL Server.
Example on a <bf>PostgreSQL 8.3.5</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" -v 2 \

<p>
In case you provide <tt>-</tt><tt>-fingerprint</tt> together with <tt>-</tt><tt>-dbms</tt>,
sqlmap will only perform the extensive fingerprint for the specified
database management system, read below for further details.
<p>
Note that this option is <bf>not</bf> mandatory and it is strongly
recommended to use it <bf>only if you are absolutely sure</bf> about the
back-end database management system. If you do not know it, let sqlmap
automatically identify it for you.
<sect2>Force the database management system operating system name
<p>
Option: <tt>-</tt><tt>-os</tt>
<p>
By default sqlmap automatically detects the web application's back-end
database management system underlying operating system when requested by
any other functionality.
At the moment the fully supported operating systems are two:
<itemize>
<item>Linux
<item>Windows
</itemize>
<p>
It is possible to force the operating system name if you already know it so
that sqlmap will skip the fingerprint.
<p>
Note that this option is <bf>not</bf> mandatory and it is strongly
recommended to use it <bf>only if you are absolutely sure</bf> about the
back-end database management system underlying operating system. If you do
not know it, let sqlmap automatically identify it for you.
<sect2>Custom injection payload
<p>
Options: <tt>-</tt><tt>-prefix</tt> and <tt>-</tt><tt>-postfix</tt>
<p>
In some circumstances the vulnerable parameter is exploitable only if the
user provides a postfix to be appended to the injection payload.
Another scenario where these options come handy presents itself when the
user already knows that query syntax and want to detect and exploit the
SQL injection by directly providing a injection payload prefix and/or
postfix.
<p>
Example on a <bf>MySQL 5.0.67</bf> target on a page where the SQL query is:
<tt>$query = "SELECT * FROM users WHERE id=('" . $_GET['id'] . "') LIMIT 0, 1";</tt>:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_str_brackets.php?id=1" -v 3 \
-p "id" --prefix "'" --postfix "AND 'test'='test"
[...]
[hh:mm:16] [INFO] testing sql injection on GET parameter 'id' with 0 parenthesis
[hh:mm:16] [INFO] testing custom injection on GET parameter 'id'
[hh:mm:16] [TRAFFIC OUT] HTTP request:
GET /sqlmap/mysql/get_str_brackets.php?id=1%27%29%20AND%207433=7433%20AND%20
%28%27test%27=%27test HTTP/1.1
Accept-charset: ISO-8859-15,utf-8;q=0.7,*;q=0.7

[...]
[hh:mm:17] [INFO] GET parameter 'id' is custom injectable
[...]
</verb></tscreen>
<p>
As you can see, the injection payload for testing for custom injection is:
<tscreen><verb>
id=1%27%29%20AND%207433=7433%20AND%20%28%27test%27=%27test
</verb></tscreen>
which URL decoded is:
<tscreen><verb>
id=1') AND 7433=7433 AND ('test'='test
</verb></tscreen>
and makes the query syntatically correct to the page query:
<tscreen><verb>
SELECT * FROM users WHERE id=('1') AND 7433=7433 AND ('test'='test') LIMIT 0, 1
</verb></tscreen>
<p>
In this simple example, sqlmap could detect the SQL injection and exploit
it without need to provide a custom injection payload, but sometimes in
the real world application it is necessary to provide it.
<sect2>Page comparison
<p>
Options: <tt>-</tt><tt>-string</tt> and <tt>-</tt><tt>-regexp</tt>
<p>
By default the distinction of a True query by a False one (basic concept
for Inferential blind SQL injection attacks) is done comparing injected
requests page content MD5 hash with the original not injected page content
MD5 hash.
Not always this concept works because sometimes the page content changes at
each refresh even not injecting anything, for instance when the page has a
counter, a dynamic advertisment banner or any other part of the HTML which
is render dynamically and might change in time not only consequently to
user's input.
To bypass this limit, sqlmap makes it possible to manually provide a
string which is <bf>always</bf> present on the not injected page
<bf>and</bf> on all True injected query pages, but that it is <bf>not</bf>
on the False ones. This can also be achieved by providing a regular
expression.
Such information is easy for an user to retrieve, simply try to inject on
the affected URL parameter an invalid value and compare original (not
injected) page content with the injected wrong page content to identify
which string or regular expression match is on not injected and True page
only.
This way the distinction will be based upon string presence or regular
expression match and not page MD5 hash comparison.
Example on a <bf>MySQL 5.0.67</bf> target on a page which content changes
every second due to a call to PHP function <tt>time()</tt>:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int_refresh.php?id=1" \

<p>
As you can see, the string after <tt>Dynamic content</tt> changes its
value every second. In the example it is just a call to PHP
<tt>time()</tt> function, but on the real world it is usually much more
than that.
<p>
Looking at the HTTP responses page content you can see that the first five
lines of code do not change at all.
So choosing for instance the word <tt>luther</tt> as an output that is
on the not injected page content and it is not on the False page content
(because the query condition returns no output so <tt>luther</tt> is not
displayed on the page content) and passing it to sqlmap, you are able to
inject anyway.
Example on a <bf>MySQL 5.0.67</bf> target on a page which content changes
every second due to a call to PHP function <tt>time()</tt>:

As you can see, when one of these options is specified, sqlmap skips the
URL stability test.
<p>
<bf>Consider one of these options a MUST when dealing with a page

<sect2>Exclude specific page content
<p>
Options: <tt>-</tt><tt>-excl-str</tt> and <tt>-</tt><tt>-excl-reg</tt>

Another way to get around the dynamicity issue explained above is to exclude
the dynamic part from the page content before processing it.
<p>
As you see in the above example the number after <tt>Dynamic content: </tt>
was dynamic and changed each second. To get around of this problem we could
use the above explained page comparison options or exclude this snippet of
dynamic text from the page before processing it and comparing it with the
not injected page.

<sect1>Techniques
<p>
These options can be used to test for specific SQL injection technique or
to use one of them to exploit the affected parameter(s) rather than using
the default blind SQL injection technique.
<sect2>Test for stacked queries (multiple statements) support
<p>
Option: <tt>-</tt><tt>-stacked-test</tt>
<p>
It is possible to test if the web application technology supports
<bf>stacked queries</bf>, multiple statements, on the injectable

<sect2>Test for UNION query SQL injection
<p>
Options: <tt>-</tt><tt>-union-test</tt> and <tt>-</tt><tt>-union-tech</tt>
<p>
It is possible to test if the target URL is affected by a <bf>UNION query
(inband) SQL injection</bf> vulnerability.
Refer to the <em>Techniques</em> section for details on this SQL injection
technique.
<p>
Example on an <bf>Oracle XE 10.2.0.1</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/oracle/get_int.php?id=1" \
--union-test -v 1

[hh:mm:27] [INFO] testing inband sql injection on parameter 'id' with NULL bruteforcing
technique
[hh:mm:27] [INFO] the target url could be affected by an inband sql injection vulnerability
valid union: 'http://172.16.213.131/sqlmap/oracle/get_int.php?id=1 UNION ALL SELECT
NULL, NULL, NULL FROM DUAL-- AND 6558=6558'
</verb></tscreen>
<p>
By default sqlmap uses the <bf><tt>NULL</tt> bruteforcing</bf> technique to
detect the number of columns within the original <tt>SELECT</tt> statement.
It is also possible to change it to <bf><tt>ORDER BY</tt> clause
bruteforcing</bf> with the <tt>-</tt><tt>-union-tech</tt> option.
<p>
Further details on these techniques can be found <htmlurl
url="http://bernardodamele.blogspot.com/2007/07/insight-on-union-query-sql-injection.html" name="here">.
<p>
Example on a <bf>PostgreSQL 8.3.5</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_str.php?id=1" \

1262=1262'
</verb></tscreen>
<p>
As you can see, the target URL parameter <tt>id</tt> might be also
exploitable by the inband SQL injection technique.
In case a case it is strongly recommended to use this technique which saves
a lot of time.
<p>
It is strongly recommended to run at least once sqlmap with the
<tt>-</tt><tt>-union-test</tt> option to test if the affected parameter is used
within a <tt>for</tt> cycle, or similar, and in case use
<tt>-</tt><tt>-union-use</tt> option to exploit this vulnerability because it
saves a lot of time and it does not weight down the web server log file
with hundreds of HTTP requests.
<sect2>Use the UNION query SQL injection
<p>
Option: <tt>-</tt><tt>-union-use</tt>
<p>
Providing the <tt>-</tt><tt>-union-use</tt> parameter, sqlmap will first test if
the target URL is affected by an <bf>inband SQL injection</bf>
(<tt>-</tt><tt>-union-test</tt>) vulnerability then, in case it seems to be
vulnerable, it will confirm that the parameter is affected by a <bf>Full
UNION query SQL injection</bf> and use this technique to go ahead with the
exploiting.
If the confirmation fails, it will check if the parameter is affected by
a <bf>Partial UNION query SQL injection</bf>, then use it to go ahead if it
is vulnerable.
In case the inband SQL injection vulnerability is not exploitable, sqlmap
will automatically fallback on the blind SQL injection technique to go
ahead.

<p>
As you can see, sqlmap identified that the parameter is affected by a
partial inband SQL injection. Consequently, it counted the number of query
output entries and retrieved them once per time. It forces the parameter
(<tt>id</tt>) value <tt>1</tt> to its negative value <tt>-1</tt> so that
it does not return, presumibly, any output. That leaves our own <tt>UNION ALL
SELECT</tt> statement to produce one entry at a time and display only it in
the page content.
<sect1>Fingerprint
<sect2>Extensive database management system fingerprint
<p>
Options: <tt>-f</tt> or <tt>-</tt><tt>-fingerprint</tt>
<p>
By default the web application's back-end database management system
fingerprint is performed requesting a database specific function which
returns a known static value. By comparing these value with the returned
value it is possible to identify if the back-end database is effectively
the one that sqlmap expected. Depending on the DBMS being tested, a
SQL dialect syntax which is syntatically correct depending upon the
back-end DBMS is also tested.
After identifying an injectable vector, sqlmap fingerprints the back-end
database management system and go ahead with the injection with its
specific syntax within the limits of the database architecture.

As you can see, from the Microsoft SQL Server banner, sqlmap was able to
correctly identify the database management system patch level.
The Microsoft SQL Server XML versions file is the result of a sqlmap
parsing library that fetches data from Chip Andrews'
<htmlurl url="http://www.sqlsecurity.com/FAQs/SQLServerVersionDatabase/tabid/63/Default.aspx"
name="SQLSecurity.com site"> and outputs it to the XML versions file.
<sect1>Enumeration
<p>
These options can be used to enumerate the back-end database management
system information, structure and data contained in the tables. Moreover
you can run your own SQL statements.
<sect2>Banner
<p>
Option: <tt>-b</tt> or <tt>-</tt><tt>-banner</tt>
<p>
Most of the modern database management systems have a function and/or
an environment variable which returns details on the database management
system version. Also, sometimes it returns the operating system version
where the daemon has been compiled on, the operating system architecture,
and its service pack. Usually the function is <tt>version()</tt> and the
environment variable <tt>@@version</tt>.

<p>
As you can see, when you enumerate password hashes on Microsoft SQL Server
sqlmap split the hash, useful if you want to crack it.
<p>
If you provide <tt>CU</tt> as username it will consider it as an alias for
current user and will retrieve the password hashes for this user.

<p>
Note that on Microsoft SQL Server the <tt>master</tt> database is not
considered a system database because some database administrators use it
as a users' database.
<sect2>Execute custom SQL statement
<p>
Options: <tt>-</tt><tt>-sql-query</tt> and <tt>-</tt><tt>-sql-shell</tt>
<p>
The SQL query and the SQL shell features makes the user able to execute
custom SQL statements on the web application's back-end database
management.
sqlmap automatically dissects the provided statement, determines which
technique to use to inject it and how to pack the SQL payload accordingly.
If it is a <tt>SELECT</tt> statement, sqlmap will retrieve its output
through the blind SQL injection or UNION query SQL injection technique
depending on the user's options. Otherwise it will execute the query
through the stacked query SQL injection technique if the web application
supports multiple statements on the back-end database management system.
<p>
Examples on a <bf>Microsoft SQL Server 2000 Service Pack 0</bf> target:
<tscreen><verb>

<p>
As you can see from the last example, sqlmap splits provided query into two
different <tt>SELECT</tt> statements for it to be able to retrieve the
output even in case when using the blind SQL injection technique.
Otherwise, in UNION query SQL injection technique it only performs a single
HTTP request to get the user's query output:

<p>
If your <tt>SELECT</tt> statement contains a <tt>FROM</tt> clause, sqlmap
asks the user if such statement can return multiple entries. In that
case the tool knows how to unpack the query correctly to retrieve its
whole output, entry per entry, when going through blind SQL injection
technique. In provided example, UNION query SQL injection it retrieved
the whole output in a single response.
<p>
Example on a <bf>PostgreSQL 8.3.5</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --sql-query \
"SELECT usename FROM pg_user" -v 0
[hh:mm:32] [INPUT] can the SQL query provided return multiple entries? [Y/n] y
[hh:mm:37] [INPUT] the SQL query provided can return up to 3 entries. How many entries
do you want to retrieve?

[#] Specific number
[q] Quit
Choice: 2
SELECT usename FROM pg_user [2]:

<p>
As you can see from the last example, sqlmap counts the number of entries
for a given query and asks for number of entries to dump.
Otherwise, if the <tt>LIMIT</tt> is also specified, or similar clause,
sqlmap will not ask for anything. It will just unpack the query and return its
output, entry per entry, when going through blind SQL injection technique.
In a given example, sqlmap used UNION query SQL injection to retrieve the
whole output in a single response.

As you can see from the example, if the <tt>SELECT</tt> statement has
an asterisk instead of the column(s) name, sqlmap first retrieves all
column names of the current table, asks if the query can return multiple
entries and goes on.

Example of SQL statement other than <tt>SELECT</tt> on a <bf>PostgreSQL
8.3.5</bf> target:

<p>
As you can see from the example, when the user provides a SQL statement
other than <tt>SELECT</tt>, sqlmap recognizes it, tests if the web
application supports stacked queries and in case it does, it executes
the provided SQL statement in a multiple statement mode.
<p>
Beware that some web application technologies do not support stacked
queries on specific database management systems. For instance, PHP does
not support stacked queries when the back-end DBMS is MySQL, but it does
support when the back-end DBMS is PostgreSQL.
<sect1>User-defined function injection
<sect2>Inject custom user-defined functions (UDF)
<p>
Options: <tt>-</tt><tt>-udf-inject</tt> and <tt>-</tt><tt>-shared-lib</tt>
<p>
You can inject your own user-defined functions (UDFs) by compiling a
MySQL or PostgreSQL shared library, DLL for Windows and shared object for
Linux/Unix, then provide sqlmap with the path where the shared library
is stored locally on your machine. sqlmap will then ask you some
questions, upload the shared library on the database server file system,
create the user-defined function(s) from it and, depending on your
options, execute them. When you are finished using the injected UDFs,
sqlmap can also remove them from the database for you.
<p>
Example on a <bf>PostgreSQL 8.4</bf>:
<tscreen><verb>
$ python sqlmap.py -u http://172.16.213.131/sqlmap/pgsql/get_int8.4.php?id=1 --udf-inject -v 0
[...]
web application technology: PHP 5.2.6, Apache 2.2.9
back-end DBMS: PostgreSQL
which is the local path of the shared library? udf/postgresql/linux/8.4/lib_postgresqludf_sys.so
how many user-defined functions do you want to create from the shared library? 1
what is the name of the UDF number 1? sys_eval
how many input parameters takes UDF 'sys_eval'? (default: 1)
what is the data-type of input parameter number 1? (default: text)
what is the data-type of the return value? (default: text)
do you want to call your injected user-defined functions now? [Y/n/q] y
which UDF do you want to call?
[1] sys_eval
[q] Quit
> 1
what is the value of the parameter number 1 (data-type: text)? echo test
do you want to retrieve the return value of the UDF? [Y/n]
return value: 'test'
do you want to call this or another injected UDF? [Y/n] n
do you want to remove UDF 'sys_eval'? [Y/n]
[12:00:10] [WARNING] remember that UDF shared object files saved on the file system can only
be deleted manually
</verb></tscreen>
<p>
If you want, you can specify the shared library local file system path
via command line using <tt>-</tt><tt>-shared-lib</tt> option.
<sect1>File system access
<sect2>Read a file from the database server's file system
<p>
Option: <tt>-</tt><tt>-read-file</tt>
<p>
It is possible to retrieve the content of files from the underlying file
system when the back-end database management system is either MySQL,
PostgreSQL or Microsoft SQL Server, and the session user has the needed
privileges to abuse database specific functionalities and architectural
weaknesses.
The file specified can be either a text or a binary file. sqlmap will
handle it automatically.

Options: <tt>-</tt><tt>-os-cmd</tt> and <tt>-</tt><tt>-os-shell</tt>
<p>
It is possible to execute arbitrary commands on the underlying operating
system when the back-end database management system is either MySQL,
PostgreSQL or Microsoft SQL Server, and the session user has the needed
privileges to abuse database specific functionalities and architectural
weaknesses.
<p>
On MySQL and PostgreSQL, sqlmap uploads (via the file upload functionality
explained above) a shared library (binary file) containing two
user-defined functions, <tt>sys_exec()</tt> and <tt>sys_eval()</tt>, then
it creates these two functions on the database and call one of them to
execute the specified command, depending on the user's choice to display
the standard output or not.
On Microsoft SQL Server, sqlmap abuses the <tt>xp_cmshell</tt> stored
procedure: if it's disabled, sqlmap re-enables it; if it does not exist,
sqlmap creates it from scratch.
<p>
If the user wants to retrieve the command standard output, sqlmap will use
one of the enumeration SQL injection techniques (blind or inband) to
retrieve it or, in case of stacked query SQL injection technique,
sqlmap will execute the command without returning anything to the user.
<p>
These techniques are detailed in the white paper

As you can see from this second example, sqlmap firstly check if the two
user-defined functions are already created, if so, it asks the user if he
wants to recreate them or keep them and save time.
<sect2>Prompt for an out-of-band shell, Meterpreter or VNC
<p>
Options: <tt>-</tt><tt>-os-pwn</tt>, <tt>-</tt><tt>-priv-esc</tt>, <tt>-</tt><tt>-msf-path</tt> and <tt>-</tt><tt>-tmp-path</tt>
<p>
It is possible to establish an <bf>out-of-band stateful TCP connection
between the user machine and the database server</bf> underlying operating
system. This channel can be an interactive command prompt, a Meterpreter
session or a graphical user interface (VNC) session as per user's choice.
sqlmap relies on Metasploit to create the shellcode and implements four
different techniques to execute it on the database server. These
techniques are:
<itemize>
<item>Database <bf>in-memory execution of the Metasploit's shellcode</bf>
via sqlmap own user-defined function <tt>sys_bineval()</tt>. Supported on
MySQL and PostgreSQL.
<item>Upload and execution of a Metasploit's <bf>stand-alone payload
stager</bf> via sqlmap own user-defined function <tt>sys_exec()</tt> on
MySQL and PostgreSQL or via <tt>xp_cmdshell()</tt> on Microsoft SQL
Server.
<item>Execution of Metasploit's shellcode by performing a <bf>SMB
reflection attack</bf> (<htmlurl
url="http://www.microsoft.com/technet/security/Bulletin/MS08-068.mspx"
name="MS08-068">) with a UNC path request from the database server to
the user's machine where the Metasploit <tt>smb_relay</tt> server exploit
runs.
<item>Database in-memory execution of the Metasploit's shellcode by
exploiting <bf>Microsoft SQL Server 2000 and 2005
<tt>sp_replwritetovarbin</tt> stored procedure heap-based buffer
overflow</bf> (<htmlurl
url="http://www.microsoft.com/technet/security/bulletin/ms09-004.mspx"
name="MS09-004">) with automatic DEP bypass.
</itemize>
<p>
Note that this feature is not supported by sqlmap running on Windows
because it relies on Metasploit's <tt>msfcli</tt> which is not
available for Windows.
<p>
These techniques are detailed in the white paper
<htmlurl url="http://sqlmap.sourceforge.net/doc/BlackHat-Europe-09-Damele-A-G-Advanced-SQL-injection-whitepaper.pdf"

If the back-end database management system runs on Windows as
<tt>Administrator</tt> and the system is not patched against Microsoft
Security Bulletin <htmlurl url="http://www.microsoft.com/technet/security/Bulletin/MS08-068.mspx"
name="MS08-068">, sqlmap can abuse the universal naming convention (UNC)
feature within any database management system to force the database server
to initiate a SMB connection with the attacker host, then perform a SMB
authentication relay attack in order to establish a high-privileged
<bf>out-of-band TCP stateful channel</bf> between the attacker host and
the target database server.
sqlmap relies on <htmlurl url="http://metasploit.com/framework"
name="Metasploit">'s SMB relay exploit to perform this attack.
You need to run sqlmap as a privileged user (e.g. <bf>root</bf>) if you
want to perform a SMB relay attack because it will need to listen on a
user-specified SMB TCP port for incoming connection attempts.
<p>
Note that this feature is not supported by sqlmap running on Windows

not fully working on Windows.

<sect2>Database stored procedure heap-based buffer overflow exploit
<p>
Options: <tt>-</tt><tt>-os-bof</tt>, <tt>-</tt><tt>-priv-esc</tt> and <tt>-</tt><tt>-msf-path</tt>
<p>
If the back-end database management system is Microsoft SQL Server not
patched against Microsoft Security Bulletin
<htmlurl url="http://www.microsoft.com/technet/security/Bulletin/MS09-004.mspx"
name="MS09-004">, sqlmap can exploit the heap-based buffer overflow
affecting <tt>sp_replwritetovarbin</tt> stored procedure in order to
establish an <bf>out-of-band TCP stateful channel</bf> between the
attacker host and the target database server.
sqlmap has its own exploit to trigger the vulnerability, but it relies on
<htmlurl url="http://metasploit.com/framework" name="Metasploit"> to
generate the shellcode used within the exploit.
<p>
Note that this feature is not supported by sqlmap running on Windows
platform because it relies on Metasploit's <tt>msfcli</tt> which is not
available for Windows.
<p>
This technique is detailed in the white paper
<htmlurl url="http://sqlmap.sourceforge.net/doc/BlackHat-Europe-09-Damele-A-G-Advanced-SQL-injection-whitepaper.pdf"
name="Advanced SQL injection to operating system full control"> and in the
slide deck <htmlurl url="http://www.slideshare.net/inquis/expanding-the-control-over-the-operating-system-from-the-database"

<sect1>Windows registry access
<p>
It is possible to access Windows registry when the back-end
database management system is either MySQL, PostgreSQL or
Microsoft SQL Server, and when the underlying database layer
supports stacked SQL queries. Also, session user has to have
the needed privileges to access it.
<sect2>Read a Windows registry key value

<sect2>Auxiliary registry switches
<p>
Options: <tt>-</tt><tt>-reg-key</tt>, <tt>-</tt><tt>-reg-value</tt>,
<tt>-</tt><tt>-reg-data</tt> and <tt>-</tt><tt>-reg-type</tt>
<p>
These switches can be used to provide data needed for proper running of
options <tt>-</tt><tt>-reg-read</tt>, <tt>-</tt><tt>-reg-add</tt> and
<tt>-</tt><tt>-reg-del</tt>. So, instead of providing registry key
information when asked, you can use them at command prompt as program
arguments.
<p>
With <tt>-</tt><tt>-reg-key</tt> option you specify used windows
registry key path, with <tt>-</tt><tt>-reg-value</tt> value item
name inside provided key, with <tt>-</tt><tt>-reg-data</tt> value
data, while with <tt>-</tt><tt>-reg-type</tt> option you specify
type of the value item.
<p>
So, another way of running example from option
<tt>-</tt><tt>-reg-add</tt> could be:
<tscreen><verb>
$ python sqlmap.py -u http://172.16.213.128/sqlmap/pgsql/get_int.php?id=1 --reg-add \
--reg-key=HKEY_LOCAL_MACHINE\SOFTWARE\sqlmap --reg-value=Test --reg-type=REG_SZ --reg-data=1
</verb></tscreen>
<sect1>Miscellaneous
<sect2>Session file: save and resume all data retrieved
<p>
Option: <tt>-s</tt>
<p>
By default sqlmap logs all queries and their output into a text file while
performing whatever request, both in blind SQL injection and in inband SQL
injection.
This is useful if you stop the injection and resume it after some time.
<p>
The default session file is <tt>output/hostname/session</tt>, but you can
change its path with the <tt>-s</tt> option.
<p>
Example on a <bf>PostgreSQL 8.3.5</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" -b \

<sect2>Flush session file for current target
<p>
Option: <tt>-</tt><tt>-flush-session</tt>

As you are already familiar with the concept of a session file from the

the content of that same file using option <tt>-</tt><tt>-flush-session</tt>.
This way you can avoid caching mechanisms implemented by default in
sqlmap. Other possible way is the manual removing of session file(s),

Option: <tt>-</tt><tt>-gpage</tt>
<p>
Default sqlmap behavior with option <tt>-g</tt> is to do a Google
search and use resulting urls from first (100) result page for further
sql injection testing. In combination with this option you can specify
some other page other than the first one for retrieving target urls.
<p>
Example of Google dorking with expression <tt>login ext:php</tt>
and resulting page set to 3:
<tscreen><verb>
$ python sqlmap.py -g "ext:php login" --gpage 3 -v 1
[hh:mm:14] [INFO] first request to Google to get the session cookie
[hh:mm:14] [INFO] using Google result page #3

<sect2>Update sqlmap
<p>
Option: <tt>-</tt><tt>-update</tt>
<p>
Using this option you can update the program to the latest version
directly from the Subversion repository along with the latest
Microsoft SQL Server XML versions file from Chip Andrews'
<htmlurl url="http://www.sqlsecurity.com/FAQs/SQLServerVersionDatabase/tabid/63/Default.aspx"
name="SQLSecurity.com site">.
<tscreen><verb>
$ python sqlmap.py --update

</verb></tscreen>
<p>
The Debian and Red Hat installation packages (deb and rpm) as well as the
Windows binary package (exe) can not be used to update sqlmap. You need
a source package (gzip, bzip2 or zip) to use this feature.
<sect2>Save options in a configuration INI file
<p>
Option: <tt>-</tt><tt>-save</tt>
<p>
It is possible to save the command line options to a configuration INI
file.
<p>
Example on a <bf>PostgreSQL 8.3.5</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" -b \
-v 1 --save
[hh:mm:33] [INFO] saved command line options on '/home/inquis/sqlmap/sqlmap-SAUbs.conf'

[hh:mm:33] [INFO] testing if the url is stable, wait a few seconds

</verb></tscreen>
<p>
As you can see, sqlmap saved the command line options to a configuration
INI file, <tt>sqlmap-SAUbs.conf</tt>.

The file is a valid sqlmap configuration INI file.
You can edit the configuration options as you wish and pass it to sqlmap
with the <tt>-c</tt> option as explained above in section 5.2.5:
<tscreen><verb>
$ python sqlmap.py -c sqlmap-SAUbs.conf
[...]
banner: 'PostgreSQL 8.3.5 on i486-pc-linux-gnu, compiled by GCC gcc-4.3.real
(Ubuntu 4.3.2-1ubuntu11) 4.3.2'
</verb></tscreen>
<sect2>Act in non-interactive mode
<p>
Option: <tt>-</tt><tt>-batch</tt>
<p>
If you want sqlmap to run as a batch tool, without any user's interaction
when sqlmap requires it, you can force it by using <tt>-</tt><tt>-batch</tt>
option, and leave sqlmap to go for a default behaviour.
<p>
Example on a <bf>MySQL 5.0.67</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int_str.php?id=1&amp;name=luther" \

<p>
As you can see, sqlmap by default chose the injection payload to the first
vulnerable parameter.
<sect2>Cleanup the DBMS by sqlmap specific UDF(s) and table(s)
<p>
Option: <tt>-</tt><tt>-cleanup</tt>
<p>
It is recommended to clean up the back-end database management system from
sqlmap temporary table(s) and created user-defined function(s) when you
are done with owning the underlying operating system or file system.
<p>
Example on a <bf>PostgreSQL 8.3.5</bf> target:
<tscreen><verb>
$ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/iis/get_int.aspx?id=1" \
