* Advisory ID: DRUPAL-SA-CONTRIB-2011-022 * Project: cosign [1] (third-party module) * Version: 6.x * Date: 2011-MONTH-XX * Security risk: Less critical [2] * Exploitable from: Remote * Vulnerability: SQL Injection -------- DESCRIPTION --------------------------------------------------------- Under certain conditions the module deletes uid 1 and then does an unparameterized db_query to insert a new uid 1. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer site configuration" and must be able to remotely manipulate the web server environmental variables REMOTE_USER and REMOTE_REALM. -------- VERSIONS AFFECTED --------------------------------------------------- * 6.x-1.4 * 6.x-1.5 * 6.x-1.6 Drupal core is not affected. If you do not use the contributed cosign [3] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Cosign module for Drupal 6.x, upgrade to version 6.x-1.7. See also the cosign [4] project page. -------- REPORTED BY --------------------------------------------------------- * Steven Merrill [5] -------- FIXED BY ------------------------------------------------------------ * Kris Steinhoff [6] the module maintainer -------- 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 [7].
