(Vendor Issues Fix) SCT Campus Pipeline Javascript Event Input Validation Holes Let Remote Users Execute Arbitrary Commands
SecurityTracker Alert ID:  1009850
SecurityTracker URL:  http://securitytracker.com/id/1009850
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Apr 18 2004
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  

Description:   A vulnerability was reported in SCT Campus Pipeline. A remote user can conduct cross-site scripting attacks to cause a target user to execute arbitrary application commands.

Spiffomatic64 reported that the e-mail interface does not filter certain scripting handles such as onload(), onmouseover(), and onclick(). A remote user can send a specially crafted e-mail 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 SCT Campus Pipeline 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 content is provided in the Source Message.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the SCT Campus Pipeline 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:   The vendor has issued a fix for the SCT Campus Pipeline Web Platform, SCT Luminis Platform II, and SCT Luminis Platform III products. For information on the fix, see answer ID 923 at the customer support site:
