-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0885 -- [Win][UNIX/Linux][OSX] Talk, Mailhandler (Drupal third-party modules) - Cross site scripting, SQL injection 18 September 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Talk Mailhandler Publisher: Drupal Operating System: UNIX variants (UNIX, Linux, OSX) Windows Impact: Execute Arbitrary Code/Commands Cross-site Scripting Access: Remote/Unauthenticated Original Bulletin: http://drupal.org/node/309758 http://drupal.org/node/309769 - --------------------------BEGIN INCLUDED TEXT-------------------- - ------------SA-2008-049 - TALK - MULTIPLE VULNERABILITIES------------ * Advisory ID: DRUPAL-SA-2008-049 * Project: Talk (third-party module) * Version: 5.x, 6.x * Date: 2008-September-17 * Security risk: Moderately critical * Exploitable from: Remote * Vulnerability: Cross site scripting, Node access bypass - ------------DESCRIPTION------------ The Talk module for Drupal 5.x and 6.x creates a "Talk" tab for nodes in which the comments belonging to the node are displayed. Two vulnerabilities and weaknesses were discovered in the contributed Talk module. CROSS SITE SCRIPTING The node title is treated as if it was safe text, and is not escaped before being displayed. This allows users to insert arbitrary HTML and script code into the Talk pages. Wikipedia has more information about such cross site scripting [http://en.wikipedia.org/wiki/Xss ] (XSS) attacks. NODE ACCESS BYPASS To view the comments of a normal node, you must view the node page itself, and thus you must always have access to view a node before you can view its comments. The Talk module bypassed this by displaying comments on a separate page and not confirming that a user has access to view the node before displaying the comments. - ------------VERSIONS AFFECTED------------ * Talk for Drupal 5.x before version 5.x-1.3 * Talk for Drupal 6.x before version 6.x-1.5 Drupal core is not affected. If you do not use the contributed Talk module, there is nothing you need to do. - ------------SOLUTION------------ Install the latest version: * If you currently use Talk 5.x-1.x upgrade to Talk 5.x-1.3 [ http://drupal.org/node/309760 ] * If you currently use Talk 6.x-1.x upgrade to Talk 6.x-1.5 [ http://drupal.org/node/309759 ] See also the Talk project page [ http://drupal.org/project/talk ]. - ------------REPORTED BY------------ * christefano [ http://drupal.org/user/104 ] - ------------CONTACT------------ The security contact for Drupal can be reached at security at drupal.org or via the form at [ http://drupal.org/contact ]. - ------------SA-2008-050 - MAILHANDLER - SQL INJECTION------------ * Advisory ID: DRUPAL-SA-2008-050 * Project: Mailhandler (third-party module) * Versions: 5.x and 6.x * Date: 2008-September-17 * Security risk: Critical * Exploitable from: Remote * Vulnerability: SQL injection - ------------DESCRIPTION------------ The Mailhandler module allows users to create or edit nodes and comments via email. One vulnerability was found in the module. SQL Injection Mailhandler does not properly use the Drupal database API and inserts values from mails directly into queries. This can be exploited to perform SQL Injection attacks [ http://en.wikipedia.org/wiki/Sql_injection ]. These attacks may lead to a malicious user gaining administrator access. - ------------VERSIONS AFFECTED------------ * Versions of Mailhandler for Drupal 5.x prior to 5.x-1.4 * Versions of Mailhandler for Drupal 6.x prior to 6.x-1.4 Drupal core is not affected. If you do not use the Mailhandler module, there is nothing you need to do. - ------------SOLUTION------------ Install the latest version. * If you use Mailhandler for Drupal 5.x upgrade to Mailhandler 5.x-1.4 [http://drupal.org/node/309771 ] * If you use Mailhandler for Drupal 6.x upgrade to Mailhandler 6.x-1.4 [http://drupal.org/node/309770 ] Also see the Mailhandler project page [ http://drupal.org/project/mailhandler]. - ------------REPORTED BY------------ * The SQL injection vulnerability was reported by the module maintainer Zohar Stolar [ http://drupal.org/user/48488 ]. - ------------CONTACT------------ The security contact for Drupal can be reached at security at drupal.org or via the form at [ http://drupal.org/contact ] and by selecting the security issues category. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
