CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
MKPortal 1.x
http://secunia.com/product/9502/

DESCRIPTION:
Demential has discovered a vulnerability in MKPortal, which can be
exploited by malicious people to conduct cross-site request forgery
attacks.

The application allows administrators to perform certain actions via
HTTP requests without performing any validity checks to verify the
request. This can e.g. be exploited to delete arbitrary shoutbox
messages when an administrator logs in.

Successful exploitation requires that the target is a valid user.

The vulnerability is confirmed in version 1.1.1 (installed on phpBB).
Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
