Overview: "Zen Cart™ truly is the art of e-commerce; a free, user-friendly, open source shopping cart system." Description: An input validation vulnerability has been reported in Zen Cart, allowing a remote user to inject SQL commands. The '/admin/login.php' file does not properly validate user-supplied input in the "admin_name" and "admin_pass" variables. A remote user can create a specially crafted HTTP POST request to inject SQL commands to be executed by the underlying database. Affected: Zen Cart version 1.1.2d. Solution: Edit source to ensure user-supplied input is correctly verified and filter malicious characters and character sequences in a HTTP proxy or firewall with URL filtering capabilities.
