SA-CONTRIB-2009-069 - Shared Sign On - Cross Site Scripting
by security-news＠drupal.org 30 Sep '09

30 Sep '09

* Advisory ID: DRUPAL-SA-CONTRIB-2009-069 * Project: Shared Sign On (third-party module) * Version: 5.x, 6.x * Date: 2009 September 30 * Security risk: Critical * Exploitable from: Remote * Vulnerability: Multiple vulnerabilities -------- DESCRIPTION --------------------------------------------------------- The Shared Sign On module enables users to log into one Drupal site and be automatically logged into multiple related Drupal sites. The module suffers multiple vulnerabilities, including Cross Site Request Forgeries (CSRF [1]) and Session fixation problem (Session Fixation [2]). This problem allows an attacker to hijack the account of a logged in user by tricking them into visiting a seemingly innocent page. -------- VERSIONS AFFECTED --------------------------------------------------- * Versions of Shared Sign On for both Drupal 5.x and Drupal 6.x Drupal core is not affected. If you do not use the contributed Shared Sign On module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ The Shared Sign On module is marked as un-supported. A separate project called Single Sign On [3] has been created as a replacement. Download the Single Sign On module and carefully read the README.txt as there is a risk of breaking a site if instructions are not carried out correctly. -------- REPORTED BY --------------------------------------------------------- * Reported by Jose A. Reyero [4] and Steven Wittens [5]. -------- FIXED BY ------------------------------------------------------------ * Fixed by Steven Wittens [6] of Strutta Inc. and Jakub Suchy [7] of Drupal Security team and Heine Deelstra [8] of Drupal Security Team. -------- CONTACT ------------------------------------------------------------- The security contact for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact.

by security-news＠drupal.org 30 Sep '09

30 Sep '09

* Advisory ID: DRUPAL-SA-CONTRIB-2009-068 * Project: Boost (third-party module) * Version: 6.x-1.* * Date: 2009-09-30 * Security risk: Low * Exploitable from: Remote * Vulnerability: Filesystem Directory Creation -------- DESCRIPTION --------------------------------------------------------- The Boost module provides a static file-based cache of Drupal pages for anonymous users. A vulnerability in the module allows an attacker to create new directories inside the webroot that the web server can write to. Existing directories cannot be changed using this vulnerability, but it can be used to affect the system by creating enough directories to reach the 35,000 limit. -------- VERSIONS AFFECTED --------------------------------------------------- * Boost module before version 6.x-1.03 Drupal core is not affected. If you do not use the contributed Boost module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Boost module for Drupal 6.x upgrade to Boost module 6.x-1.03 [1] -------- REPORTED BY --------------------------------------------------------- Hans Rossel [2] -------- FIXED BY ------------------------------------------------------------ Mike Carper [3] the module maintainer. -------- CONTACT ------------------------------------------------------------- The security contact for Drupal can be reached at security at drupal.org [4] or via the form at http://drupal.org/contact [5].
