PowerPortal Input Validation Hole in Private Message Title Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1010802
SecurityTracker URL:  http://securitytracker.com/id/1010802
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jul 29 2004
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 1.3
Description:   vamp^ reported an input validation vulnerability in PowerPortal in the private message module. A remote user can conduct cross-site scripting attacks.

It is reported that the private_messages module does not properly filter HTML code from user-supplied input in the message title field. A remote user can send a specially crafted private message 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 PowerPortal 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.

According to the report, user passwords are stored in cookies in clear text.

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

With access to the target user's cookies, the remote user can obtain the target user's actual password (as it is stored in clear text in a cookie).

Solution:   No solution was available at the time of this entry.
Vendor URL:  powerportal.sourceforge.net/ (Links to External Site)
Cause:   Access control error, Input validation error
Underlying OS:  Linux (Any), UNIX (Any), Windows (Any)

Message History:   None.
