The weakness was released 08/06/2014 by Willis Vandevanter and Nir Goldshlager as SA-CORE-2014-004 as confirmed advisory (Website). The advisory is shared at drupal.org. The public release was coordinated with the project team. This vulnerability is known as CVE-2014-5266 since 08/15/2014. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 82202 (Debian DLA-56-1 : wordpress security update), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 122561 (Fedora Security Update for drupal7 (FEDORA-2014-9278)).

Upgrading to version 6.33 or 7.31 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at cgit.drupalcode.org. The best possible mitigation is suggested to be upgrading to the latest version. The advisory contains the following remark:

If you are unable to install the latest version of Drupal immediately, you can alternatively remove the xmlrpc.php file from the root of Drupal core (or add a rule to .htaccess to prevent access to xmlrpc.php) and disable the OpenID module. These steps are sufficient to mitigate the vulnerability in Drupal core if your site does not require the use of XML-RPC or OpenID functionality. However, this mitigation will not be effective if you are using a contributed module that exposes Drupal's XML-RPC API at a different URL (for example, the Services module); updating Drupal core is therefore strongly recommended.
Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 16786.

The vulnerability is also documented in the databases at X-Force (95344) and Tenable (82202). Entries connected to this vulnerability are available at 67378, 67379, 67382 and 68539.
