(Vendor Issues Fix) Re: XOOPS Portal Input Validation Flaw in IMG Tags Lets Remote Users Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1005300
SecurityTracker URL:  http://securitytracker.com/id/1005300
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Sep 26 2002
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): RC3.0.4
Description:   An input validation vulnerability was reported in the XOOPS portal software. A remote user can cause arbitrary javascript to be executed on an XOOPS user's computer.

It is reported that a remote user can insert javascript in a news post, as shown:

<IMG SRC="javascript:[javascript]">

When the news post is viewed by a target user, arbitrary scripting code will be executed by the target user's browser. The code will originate from the site running XOOPS 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 has reportedly been notified.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with an XOOPS 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.
Solution:   The vendor has issued a fixed version (RC3.0.5) and recommends that all users upgrade.
