Description:
A vulnerability was reported in cpCommerce. A remote user can conduct cross-site scripting attacks.
The software does not properly filter HTML code from user-supplied input before displaying the input. A remote user can create a specially crafted POST request that, when submitted by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the cpCommerce software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
The 'search' parameter in 'search.php' and the 'name' parameter in 'sendtofriend.php' are affected.
The vendor was notified on September 23, 2008.
