PHP-Nuke Yellow_Pages Module - 'cid' SQL Injection

source: https://www.securityfocus.com/bid/28109/info

The Yellow_Pages module for PHP-Nuke 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.

This issue affects the Yellow_Pages 1; other versions may also be vulnerable.
