ViArt Shop Input Validation Holes Permit Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1013853
SecurityTracker URL:  http://securitytracker.com/id/1013853
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Updated:  May 2 2005
Original Entry Date:  May 2 2005
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 2.1.6
Description:   Lostmon reported a vulnerability in ViArt Shop. A remote user can conduct cross-site scripting attacks.

The 'basket.php', 'forum.php', 'page.php', 'reviews.php', 'products.php', and 'news_view.php' scripts do not properly validate user-supplied input to remove HTML code. A remote user can create a specially crafted URL that, when loaded 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 ViArt Shop 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.

Some demonstration exploit URLs are provided:
