Replaces each keyword character with random case value
|
|
|
|
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 and bespoke web application firewalls
|
|
that has poorly written permissive regular expressions
|
|
* This tamper script should work against all (?) databases
