TinX CMS 'rss.php' SQL Injection Vulnerability

Summary
TinX CMS 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. Versions prior to TinX CMS 3.5.1 are vulnerable.
Solution
The vendor has released an update. See http://sourceforge.net/project/showfiles.php?group_id=133415 for more information.
