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.
