Yet Another Bulletin Board (YaBB) 1.40 and 1.41 does not require a user to submit the correct password before changing it to a new password, which allows remote attackers to modify passwords by stealing the cookie of another user, modifying the expiretime setting, and submitting the change in a profile2 action to index.php.
