* 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.

SA-CORE-2009-008 - Drupal core - Multiple vulnerabilities
by security-news＠drupal.org 16 Sep '09

16 Sep '09

* Advisory ID: DRUPAL-SA-CORE-2009-008 * Project: Drupal core * Version: 5.x, 6.x * Date: 2009-September-16 * Security risk: Critical * Exploitable from: Remote * Vulnerability: Multiple vulnerabilities -------- DESCRIPTION --------------------------------------------------------- Multiple vulnerabilities and weaknesses were discovered in Drupal. .... OpenID association cross site request forgeries The OpenID module in Drupal 6 allows users to create an account or log into a Drupal site using one or more OpenID identities. The core OpenID 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. This issue affects Drupal 6.x only. .... 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. This issue affects Drupal 6.x only. .... File upload File uploads with certain extensions are not correctly processed by the File API. This may lead to the creation of files that are executable by Apache. The .htaccess that is saved into the files directory by Drupal should normally prevent execution. The files are only executable when the server is configured to ignore the directives in the .htaccess file. This issue affects Drupal 6.x only. .... Session fixation Drupal doesn't regenerate the session ID when an anonymous user follows the one time login link used to confirm email addresses and reset forgotten passwords. This enables a malicious user to fix and reuse the session id of a victim under certain circumstances. This issue affects Drupal 5.x only. -------- VERSIONS AFFECTED --------------------------------------------------- * Drupal 6.x before version 6.14. * Drupal 5.x before version 5.20. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you are running Drupal 6.x then upgrade to Drupal 6.14 [2]. * If you are running Drupal 5.x then upgrade to Drupal 5.20 [3]. If you are unable to upgrade immediately, you can apply a patch to secure your installation until you are able to do a proper upgrade. Theses patches fix the security vulnerabilities, but do not contain other fixes which were released in Drupal 6.14 or Drupal 5.20. * To patch Drupal 6.13 use SA-CORE-2009-008-6.13.patch [4]. * To patch Drupal 5.19 use SA-CORE-2009-008-5.19.patch [5]. *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. -------- REPORTED BY --------------------------------------------------------- The session fixation issue was reported by Noel Sharpe [6]. OpenID impersonation was reported by Robert Metcalf [7]. OpenID association CSRF was reported by Heine Deelstra [8] (*). The file upload issue was reported by Heine Deelstra [9] (*). (*) Member of the Drupal security team -------- FIXED BY ------------------------------------------------------------ The session fixation issue was fixed by Jakub Suchy [10]. The OpenID and file upload issues were fixed by Heine Deelstra [11]. -------- CONTACT ------------------------------------------------------------- The security team 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.
