Cross-site scripting vulnerability in SunShop 2.5 and earlier allows remote attackers to gain administrative privileges to SunShop by injecting the script into fields during new customer registration.

Turnkey Web Tools SunShop Shopping Cart allows remote attackers to obtain sensitive information via a phpinfo action to (1) index.php, (2) admin/index.php, and (3) admin/adminindex.php, which executes the PHP phpinfo function.

Multiple cross-site scripting (XSS) vulnerabilities in SunShop 3.5 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) prevaction, (2) previd, (3) prevstart, (4) itemid, (5) id, and (6) action parameters in index.php.
