Url-encodes all characters in a given payload (not processing already
|
|
encoded)
|
|
|
|
Tested against:
|
|
* Microsoft SQL Server 2005
|
|
* MySQL 4, 5.0 and 5.5
|
|
* Oracle 10g
|
|
* PostgreSQL 8.3, 8.4, 9.0
|
|
|
|
Notes:
|
|
* Useful to bypass very weak web application firewalls that do not
|
|
url-decode the request before processing it through their ruleset
|
|
* The web server will anyway pass the url-decoded version behind,
|
|
hence it should work against any DBMS
