===================================================================== CERT-Renater Note d'Information No. 2009/VULN387 _____________________________________________________________________ DATE : 18/09/2009 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Systems running OpenID for Drupal 5, Comment RSS for Drupal, Date for Drupal. ====================================================================== http://drupal.org/node/579478 http://drupal.org/node/579280 http://drupal.org/node/579144 ______________________________________________________________________ - --------------------------BEGIN INCLUDED TEXT-------------------- * Advisory ID: DRUPAL-SA-CONTRIB-2009-059 * Project: OpenID (third-party module) * Version: 5.x * Date: 2009-September-16 * Security risk: Critical * Exploitable from: Remote * Vulnerability: Impersonation, cross site request forgery - -------- DESCRIPTION - --------------------------------------------------------- The contributed OpenID module for Drupal 5 allows users to create an account or log into a Drupal site using one or more OpenID identities. The module does not correctly implement Form API for the form that allows one to link user accounts with OpenID identifiers. A malicious user is therefore able to use cross site request forgeries [1] to add attacker controlled OpenID identities to existing accounts. These OpenID identities can then be used to gain access to the affected accounts. .... OpenID impersonation The OpenID module is not a compliant implementation of the OpenID Authentication 2.0 specification. An implementation error allows a user to access the account of another user when they share the same OpenID 2.0 provider. - -------- VERSIONS AFFECTED - --------------------------------------------------- * OpenID for Drupal 5.x prior to 5.x-1.3 Drupal 6.x core has a similar issue, see SA-CORE-2009-008 [2] for details. - -------- SOLUTION - ------------------------------------------------------------ Upgrade to the latest version: * If you use OpenID for Drupal 5.x upgrade to OpenID 5.x-1.3 [3] *Important note*: Some users using OpenID might not be able to use the existing OpenID associations to login after the upgrade. These users should use the one time login via password recovery to get access to their user account and re-add desired associations. These users likely had issues with OpenID logins prior to the upgrade. See also the OpenID project page [4]. - -------- REPORTED BY - --------------------------------------------------------- The OpenID impersonation was reported by Robert Metcalf [5]. The OpenID association CSRF was reported by Heine Deelstra [6] (*). (*) Member of the Drupal security team. - -------- FIXED BY - ------------------------------------------------------------ The issues were fixed by Heine Deelstra [7]. - -------- CONTACT - ------------------------------------------------------------- The security contact for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact.

The link to this feed contains the node's title. Adding the link to the RSS feed was not respecting access permissions, potentially exposing content not available otherwise. - -------- VERSIONS AFFECTED - --------------------------------------------------- * Comment RSS for Drupal 5.x before Comment RSS 5.x-2.2 * Comment RSS for Drupal 6.x before Comment RSS 6.x-2.2 Drupal core is not affected. If you do not use the contributed Comment RSS module, there is nothing you need to do. - -------- SOLUTION - ------------------------------------------------------------ Install the latest version: * If you use Drupal 5.x upgrade to Comment RSS 5.x-2.2 [2]. * If you use Drupal 6.x upgrade to Comment RSS 6.x-2.2 [3]. See also the Comment RSS [4] project page. - -------- REPORTED BY - --------------------------------------------------------- Dave Reid [5] of the Drupal Security Team [6] and co-maintainer of the Comment RSS module - -------- FIXED BY - ------------------------------------------------------------ Dave Reid [7] - -------- CONTACT - ------------------------------------------------------------- The security contact for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact.

The Date module does not properly escape user data correctly in some cases when setting the page title. A malicious user with permission to post date content could attempt a cross site scripting [1] (XSS) attack when creating or editing content, leading to the user gaining full administrative access. - -------- VERSIONS AFFECTED - --------------------------------------------------- * Date for Drupal 6.x prior to 6.x-2.4 * Date for Drupal 6.x prior to 5.x-2.8 Drupal core is not affected. If you do not use the contributed Date module, there is nothing you need to do. - -------- SOLUTION - ------------------------------------------------------------ Upgrade to the latest version: * If you use Date for Drupal 6.x upgrade to Date 6.x-2.4 [2] * If you use Date for Drupal 5.x upgrade to Date 5.x-2.8 [3] See also the Date project page [4]. - -------- REPORTED BY - --------------------------------------------------------- The Acquia, Inc. support team - -------- FIXED BY - ------------------------------------------------------------ Karen Stevenson [5], the project maintainer. - -------- CONTACT - ------------------------------------------------------------- The security contact for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact.
