The weakness was disclosed 08/06/2014 by Willis Vandevanter and Nir Goldshlager as SA-CORE-2014-004 as confirmed advisory (Website). The advisory is available at drupal.org. The public release has been coordinated in cooperation with the vendor. This vulnerability is handled as CVE-2014-5265 since 08/15/2014. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available.

The vulnerability scanner Nessus provides a plugin with the ID 77948 (Fedora 20 : drupal6-6.33-1.fc20 (2014-9281)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora 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 16721.

The vulnerability is also documented in the databases at X-Force (95345) and Tenable (77948). The entries 67381 and 68539 are pretty similar.
