A-CART Input Validation Hole in 'category.asp' Lets Remote Users Inject SQL Commands
SecurityTracker Alert ID:  1009579
SecurityTracker URL:  http://securitytracker.com/id/1009579
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Mar 29 2004
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 2.0
Description:   Manuel Lopez reported some input validation vulnerabilities in A-CART and A-CART Pro. A remote user can inject SQL commands and conduct cross-site scripting attacks.

It is reported that the 'category.asp' script does not properly validate user-supplied input in the 'catcode' variable. A remote user can request a specially crafted URL to cause arbitrary SQL commands to be executed on the underlying database. A demonstration exploit URL is provided:

http://host/category.asp?catcode=1%20union%20all%20select%20pass,0,0,0,0%20f
rom%20customers%20where%20fname='[Username]'

It is also reported that the 'deliver.asp' and 'billing.asp' scripts do not filter HTML code from user-supplied input. A remote user can submit specially crafted input that, when viewed 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 A-CART 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 vendor was reportedly notified without response.

Impact:   A remote user can inject SQL commands to be executed on the underlying database.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the A-CART 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.
