View online: http://drupal.org/node/1597414 * Advisory ID: DRUPAL-SA-CONTRIB-2012-085 * Project: BrowserID (Mozilla Persona) [1] (third-party module) * Version: 7.x * Date: 2012-May-23 * Security risk: Critical [2] * Exploitable from: Remote * Vulnerability: Cross Site Request Forgery (results in Privilege Escalation) -------- DESCRIPTION --------------------------------------------------------- CVE: Requested The BrowserID module provides integration with BrowserID (also known as Mozilla Persona) -- a Mozilla project that lets users of your site quickly and easily log in without needing to remember a password specific to your site. The module did not sufficiently validate requests for authentication to log in, potentially allowing a Cross Site Request Forgery (CSRF) attack and introducing the possibility that logging in to a malicious site with BrowserID could give that site the ability to log in to other websites using your BrowserID identity. -------- VERSIONS AFFECTED --------------------------------------------------- * BrowserID (Mozilla Persona) 7.x-1.x versions prior to 7.x-1.3. Drupal core is not affected. If you do not use the contributed BrowserID (Mozilla Persona) [3] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the BrowserID module for Drupal 7.x, upgrade to BrowserID 7.x-1.3 [4] This version adds a dependency on the Session API [5] module. Make sure you install Session API /before/ upgrading to BrowserID 7.x-1.3. Also see the BrowserID (Mozilla Persona) [6] project page. -------- REPORTED BY --------------------------------------------------------- * Isaac Sukin [7], the module maintainer -------- FIXED BY ------------------------------------------------------------ * Isaac Sukin [8], the module maintainer * Greg Knaddison [9] of the Drupal Security Team * Ben Adida [10] of Mozilla -------- 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 http://drupal.org/contact [12].
