Replaces greater than operator ('>') with 'GREATEST' counterpart
|
|
|
|
Requirement:
|
|
* MySQL
|
|
* MariaDB
|
|
* PostgreSQL
|
|
* Microsoft SQL Server >= 2022
|
|
* Oracle
|
|
|
|
Tested against:
|
|
* MySQL 8.4.9
|
|
* MariaDB 11.8.8
|
|
* PostgreSQL 16.11
|
|
* Microsoft SQL Server 2022
|
|
* Oracle 23ai
|
|
|
|
Notes:
|
|
* Useful to bypass weak and bespoke web application firewalls that
|
|
filter the greater than character
|
|
* NOT usable against SQLite, which has no GREATEST() (it overloads
|
|
MAX() for the multi-argument case instead). Microsoft SQL Server
|
|
only gained GREATEST() in 2022
|
|
|
|
>>> tamper('1 AND A > B')
|
|
'1 AND GREATEST(A,B+1)=A'
