VERIFY ADVISORY:
http://secunia.com/advisories/37475/

DESCRIPTION:
Moritz Naumann has discovered vulnerability in OpenX, which can be
exploited by malicious users to compromise a vulnerable system.

The vulnerability is caused due to the banner-edit.php script
allowing the upload of files with arbitrary extensions to a folder
inside the webroot. This can be exploited to e.g. execute arbitrary
PHP code by uploading a specially crafted PHP script that contains
the GIF magic number.

The vulnerability is confirmed in version 2.8.1. Other versions may
also be affected.

SOLUTION:
Update to version 2.8.2.

PROVIDED AND/OR DISCOVERED BY:
