View online: https://www.drupal.org/node/2340029 * Advisory ID: DRUPAL-SA-CONTRIB-2014-088 * Project: Mollom [1] (third-party module) * Version: 6.x, 7.x * Date: 2014-September-17 * Security risk: 11/25 ( Moderately Critical) AC:Complex/A:User/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2] * Vulnerability: Cross Site Scripting -------- DESCRIPTION --------------------------------------------------------- Mollom is an "intelligent" content moderation web service which determines if a post is potentially spam; not only based on the posted content, but also on the past activity and reputation of the poster across multiple sites. Mollom offers a feature to report submitted content as inappropriate which allows end users to indicate that a piece of site content is objectionable or out of place. When reporting content, the content title is not sufficiently sanitized to prevent cross-site scripting (XSS) attacks. This vulnerability is mitigated by the fact that an attacker must have a role with the permission to create content and the content type must be enabled for "Flag as Inappropriate" within the Mollom advanced configuration settings (which is not the default setting). -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- * Mollom 6.x-2.x versions from 6.x-2.7 to 6.x-2.10 * Mollom 7.x-2.x versions from 7.x-2.9 to 7.x-2.10 Drupal core is not affected. If you do not use the contributed Mollom [4] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Mollom module for Drupal 6.x, upgrade to Mollom 6.x-2.11 [5] * If you use the Mollom module for Drupal 7.x, upgrade to Mollom 7.x-2.11 [6] Also see the Mollom [7] project page. -------- REPORTED BY --------------------------------------------------------- * Matt Vance [8] -------- FIXED BY ------------------------------------------------------------ * Lisa Backer [9] the module maintainer * Matt Vance [10] -------- COORDINATED BY ------------------------------------------------------ * Greg Knaddison [11] 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 https://www.drupal.org/contact [12].
