View online: http://drupal.org/node/1840740 * Advisory ID: DRUPAL-SA-CONTRIB-2012-162 * Project: RESTful Web Services [1] (third-party module) * Version: 7.x * Date: 2012-November-14 * 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 page with a site-specific malicious HTML form submission. CVE: Requested -------- VERSIONS AFFECTED --------------------------------------------------- * RESTWS 7.x-1.x versions prior to 7.x-1.1. * RESTWS 7.x-2.x versions prior to 7.x-2.0-alpha3. Drupal core is not affected. If you do not use the contributed RESTful Web Services [3] 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-1.1 [4] * If you use the RESTWS 2.x module for Drupal 7.x, upgrade to RESTWS 7.x-2.0-alpha3 [5] Also see the RESTful Web Services [6] project page. -------- REPORTED BY --------------------------------------------------------- * Damien Tournoud [7] of the Drupal Security Team * Klaus Purer [8] of the Drupal Security Team -------- FIXED BY ------------------------------------------------------------ * Klaus Purer [9] the module maintainer -------- COORDINATED BY ------------------------------------------------------ * Klaus Purer [10] of the Drupal Security Team -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at http://drupal.org/contact [11].
