Multiple SQL injection vulnerabilities in index.php in FreeWebshop 2.2.1 allow remote attackers to execute arbitrary SQL commands via (1) the prod parameter in a details action, (2) the cat parameter in a browse list action, or (3) the group parameter in a categories action. NOTE: it was later reported that MOG - Web Shop (MOG-WebShop), a product based on the same code, is also affected.
