SA-CORE-2011-003 - Drupal core - Access bypass
by security-news＠drupal.org 27 Jul '11

27 Jul '11

* Advisory ID: DRUPAL-SA-CORE-2011-003 * Project: Drupal core [1] * Version: 7.x * Date: 2011-July-27 * Security risk: Less critical [2] * Exploitable from: Remote * Vulnerability: Access bypass -------- DESCRIPTION --------------------------------------------------------- .... Access bypass in private file fields on comments. Drupal 7 contains two new features: the ability to attach File upload fields to any entity type in the system and the ability to point individual File upload fields to the private file directory. If a Drupal site is using these features on comments, and the parent node is denied access (either by a node access module or by being unpublished), the file attached to the comment can still be downloaded by non-privileged users if they know or guess its direct URL. This issue affects Drupal 7.x only. -------- VERSIONS AFFECTED --------------------------------------------------- * Drupal 7.x before version 7.5. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you are running Drupal 7.x then upgrade to Drupal 7.5 or 7.6. The Security Team has released both a pure security update without other bug fixes and a security update combined with other bug fixes and improvements. You can choose to either only include the security update for an immediate fix (which might require less quality assurance and testing) or more fixes and improvements alongside the security fixes by choosing between Drupal 7.5 and Drupal 7.6. Read the announcement [3] for more information. See also the Drupal core [4] project page. -------- REPORTED BY --------------------------------------------------------- * The File access bypass was reported by Florian Weber [5]. -------- FIXED BY ------------------------------------------------------------ * The File access bypass was fixed by Stéphane Corlosquet [6] and Károly Négyesi [7], both members of the Drupal security team. -------- 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 [8].

SA-CONTRIB-2011-031 - SunMailer - Access bypass
by security-news＠drupal.org 20 Jul '11

20 Jul '11

* Advisory ID: SA-CONTRIB-2011-31 * Project: SunMailer Newsletter [1] (third-party module) * Version: 6.x * Date: 2011-July-20 * Security risk: Less critical [2] * Exploitable from: Remote * Vulnerability: Access bypass -------- DESCRIPTION --------------------------------------------------------- SunMailer Newsletter creates an email newsletter that users can subscribe to. The module includes a page where authenticated users can view and/or edit their newsletter subscription. Access to this page was accidentally granted to anonymous users, creating an access bypass that disclosed all user's newsletter subscription to anonymous users and also allowed anonymous users to tamper with the newsletter subscription. This vulnerability is mitigated by the fact that it does not disclose the email address of the subscriber. The exploit is also accessible only by directly accessing the URL leading to the user's subscription page; no link to the vulnerable page is shown in the user interface. -------- VERSIONS AFFECTED --------------------------------------------------- * 6.x-1.6 or prior versions Drupal core is not affected. If you do not use the contributed SunMailer Newsletter [3] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the SunMailer Newsletter module for Drupal 6.x, upgrade to version 6.x-1.7 [4] See also the SunMailer Newsletter [5] project page. -------- REPORTED BY --------------------------------------------------------- * Mike Wacker [6] the module maintainer -------- FIXED BY ------------------------------------------------------------ * Mike Wacker [7] 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 [8].

One of its features enables a highly permissioned developer to quickly switch to another user's account, without providing credentials. The module is vulnerable to Cross Site Request Forgeries (CSRF) via the links and form in the Switch User block. -------- VERSIONS AFFECTED --------------------------------------------------- * 6.x-1.24 and prior * 7.x-1.0 and prior Note: prior versions are no longer maintained by the security team.

SA-CONTRIB-2011-029 - Taxonomy Filter - Cross Site Scripting
by security-news＠drupal.org 20 Jul '11

20 Jul '11

* Advisory ID: DRUPAL-SA-CONTRIB-2011-029 * Project: Taxonomy Filter [1] (third-party module) * Version: 6.x, 7.x * Date: 2011-July-20 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Cross Site Scripting -------- DESCRIPTION --------------------------------------------------------- The Taxonomy Filter module enables users to filter taxonomy listings to find content tagged by multiple terms. Older versions of the module were susceptible to a Cross Site Scripting (XSS) attack by way of vocabulary names. The vulnerability was mitigated by the fact that an attacker must have a role with the "administer taxonomy" permission. The 6.x-1.6 release of Taxonomy Filter also corrects an XSS issue in Taxonomy Filter menu names that requires the "administer site configuration" permission. Vulnerabilities that require the "administer site configuration" permission to exploit [3] do not necessitate Security Advisories, however no Advisory had been issued for previous insecure releases. -------- VERSIONS AFFECTED --------------------------------------------------- * 6.x-1.3 and earlier * 7.x-1.x-dev Drupal core is not affected. If you do not use the contributed Taxonomy Filter [4] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Taxonomy Filter module for Drupal 6.x upgrade to 6.x-1.6 [5] * If you use the Taxonomy Filter module for Drupal 7.x upgrade to the latest 7.x-1.x-dev [6] release See also the Taxonomy Filter [7] project page. -------- REPORTED BY --------------------------------------------------------- * Sam Oldak -------- FIXED BY ------------------------------------------------------------ * Jim Berry [8] 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 [9].

* Advisory ID: DRUPAL-SA-CONTRIB-2011-027 * Project: Facebook Share [1] (third-party module) * Version: 6.x, 7.x * Date: 2011-July-06 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Cross Site Scripting -------- DESCRIPTION --------------------------------------------------------- This module enables Drupal site administrators to add a Facebook Share button to selected content type nodes. The module doesn't sufficiently check the override text or button size input fields on the module configuration form to prevent against an XSS exploit. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer facebookshare". -------- VERSIONS AFFECTED --------------------------------------------------- * Drupal 6.x-1.1 and prior * Drupal 7.x-1.2 and prior Drupal core is not affected. If you do not use the contributed Facebook Share [3] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the 6.x-1.1 or 6.x-1.0 module for Drupal 6.x upgrade to Facebook Share 6.x-1.2 [4] * If you use the 7.x-1.2 or prior module for Drupal 7.x upgrade to Facebook Share 7.x-1.3 [5] See also the Facebook Share [6] project page. -------- REPORTED BY --------------------------------------------------------- * Bèr Kessels [7] -------- FIXED BY ------------------------------------------------------------ * John Oltman [8] 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 [9].
