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

The vulnerability is caused due to the application allowing users to
perform certain actions via HTTP requests without performing any
validity checks to verify the request. This can be exploited to
delete all of a user's private messages.

The vulnerability is confirmed in version 2.0.22. Other versions may
also be affected.

SOLUTION:
Do not browse untrusted websites while logged on to phpBB.
