Vulnerability: CSRF
========================================================================

Description
-----------
A CSRF vulnerability was recently discovered and reported in OpenX
Source Security Advisory CVE-2013-5954. However, the number of places in
the code which were affected go well beyond those listed in the original
advisory.

The vulnerability allows users who are logged into the Revive Adserver
console to be tricked into deleting data from their Revive Adserver
installation. The vulnerability does not allow remote users to access
the Revive Adserver console or otherwise modify data.

Although the attack can cause loss of data and service disruptions, the
risk is rated to be moderate as the vulnerability requires the victim to
interact with the attack mechanism.

The vulnerability is also present and exploitable in OpenX Source 2.8.11
and earlier versions, potentially back to phpAdsNew 2.0.x.

Details
-------
HTTP GET methods are used extensively in the Revive Adserver web console
for deleting data or unlinking accounts etc. instead of HTTP POST. These
older style calls were not protected to prevent attack via CSRF.

The scripts that have been fixed are:

    www/admin/admin-user-unlink.php
    www/admin/advertiser-delete.php
    www/admin/advertiser-user-unlink.php
    www/admin/affiliate-delete.php
    www/admin/affiliate-user-unlink.php
    www/admin/agency-delete.php
    www/admin/agency-user-unlink.php
    www/admin/banner-delete.php
    www/admin/campaign-delete.php
    www/admin/channel-delete.php
    www/admin/tracker-delete.php,
    www/admin/userlog-delete.php
    www/admin/zone-delete.php
