It has come to our attention that there has been an attack on a number of vBulletin installations that are running older versions of the software. They are taking advantage of a known security flaw that was fixed in subsequent versions.
It is extremely important that you keep your software up-to-date in order to protect your forums against these attacks. If you are running any version lower than 2.3.4, then we strongly recommend you upgrade immediately.
If your access to download updates has expired this can be renewed by clicking the "Renew" link next to your license in the Members area.
Those not wishing to upgrade should replace calendar.php on their forum with the appropriate version attached to this post.
