* Advisory ID: DRUPAL-SA-CONTRIB-2013-003 * Project: RESTful Web Services [1] (third-party module) * Version: 7.x * Date: 2013-January-16 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Cross Site Request Forgery
-------- DESCRIPTION ---------------------------------------------------------
This module enables you to expose Drupal entities as RESTful web services. It provides a machine-readable interface to exchange resources in JSON, XML and RDF.
The module doesn't sufficiently verify POST requests thereby exposing a Cross Site Request Forgery vulnerability.
This vulnerability is mitigated by the fact that an attacker must trick an authenticated user onto a prepared page that leverages a weakness in certain browser plugins.
-------- CVE IDENTIFIER(S) ISSUED --------------------------------------------
* /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./
-------- VERSIONS AFFECTED ---------------------------------------------------
* RESTWS 7.x-1.x versions prior to 7.x-1.2. * RESTWS 7.x-2.x versions prior to 7.x-2.0-alpha4.
Drupal core is not affected. If you do not use the contributed RESTful Web Services [4] module, there is nothing you need to do.
-------- SOLUTION ------------------------------------------------------------
Install the latest version:
* If you use the RESTWS 1.x module for Drupal 7.x, upgrade to RESTWS 7.x-1.2 [5] * If you use the RESTWS 2.x module for Drupal 7.x, upgrade to RESTWS 7.x-2.0-alpha4 [6]
