ECW-Shop Input Validation Flaw in 'cat' Permits Remote Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1008522
SecurityTracker URL:  http://securitytracker.com/id/1008522
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Dec 19 2003
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 5.5, 5.01
Description:   An input validation vulnerability was reported in ECW-Shop in the processing of the 'cat' parameter. A remote user can conduct cross-site scripting attacks.

SecuriTeam credited David S. Ferreira with reporting that the 'cat' parameter does not filter HTML code from user-supplied input before displaying the user-supplied input.

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 ECW-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.

A demonstration exploit URL is provided:

http://vulnerablecode/index.php?c=srch&cat=%3Cscript%3Ealert(document.domain);%3C/script%3E

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the ECW-Shop software, 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.
Solution:   No solution was available at the time of this entry.
Vendor URL:  www.soft4e.com/shop.html (Links to External Site)
