Replaces greater than operator ('>') with 'NOT BETWEEN 0 AND #'
|
|
|
|
Example:
|
|
* Input: 'A > B'
|
|
* Output: 'A NOT BETWEEN 0 AND B'
|
|
|
|
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 weak and bespoke web application firewalls that
|
|
filter the greater than character
|
|
* The BETWEEN clause is SQL standard. Hence, this tamper script
|
|
should work against all (?) databases
