* Advisory ID: DRUPAL-SA-CONTRIB-2013-051 * Project: Services [1] (third-party module) * Version: 6.x, 7.x * Date: 2013-June-05 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Cross Site Request Forgery

-------- DESCRIPTION ---------------------------------------------------------

This module enables you to expose an API to third party systems using REST, XML-RPC or other protocols.

The module doesn't sufficiently verify writing requests (POST, PUT, DELETE) with session cookie authentication, thereby exposing a Cross Site Request Forgery vulnerability.

This vulnerability is mitigated by the fact that session based authentication must be enabled for an endpoint.

-------- CVE IDENTIFIER(S) ISSUED --------------------------------------------

* /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./

-------- VERSIONS AFFECTED ---------------------------------------------------

* Services 6.x-3.x versions. * Services 7.x-3.x versions prior to 7.x-3.4.

Drupal core is not affected. If you do not use the contributed Services [4] module, there is nothing you need to do.

-------- SOLUTION ------------------------------------------------------------

Install the latest version or uninstall the module.

* If you use the Services module for Drupal 7.x, upgrade to Services 7.x-3.4 [5] * If you use the Services module for Drupal 6.x, uninstall the module.

Note that Services clients using session authentication now should supply a special X-CSRF-Token header with a token that can be retrieved from http://example.com/services/session/token [6]. This is needed for writing HTTP methods calls (POST, PUT, DELETE).

Also see the Services [7] project page.
