http://secunia.com/advisories/30991/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
vBulletin 3.x
http://secunia.com/product/3212/

DESCRIPTION:
Some vulnerabilities have been reported in vBulletin, which can be
exploited by malicious people to conduct script insertion attacks.

Input passed via "PHP_SELF" or via the "do" parameter when requesting
a missing page is not properly sanitised before being logged. This can
be exploited to insert arbitrary HTML and script code, which is
executed in an administrator's browser session in context of an
affected site when the malicious logs are being viewed.

NOTE: Reportedly, the vulnerabilities can be exploited to inject and
execute arbitrary PHP code on an affected system.

The vulnerabilities are reported in version 3.7.2 and 3.6.10 PL2.
Prior versions may also be affected.

SOLUTION:
Update to version 3.7.2 PL1 or 3.6.10 PL3.
