* Advisory ID: DRUPAL-SA-CONTRIB-2010-020 * Project: Facebook-style Statuses (Microblog) (third-party module) * Version: 6.x-2.x * Date: 2010-February-24 * Security risk: Not Critical * Exploitable from: Remote * Vulnerability: Access bypass -------- DESCRIPTION --------------------------------------------------------- The Facebook-style Statuses (Microblog) module enables each user to have a stream of messages ("statuses") like on Facebook. Users can update their own status as well as write messages to other users by visiting the other user's profile. When a user updates his own status and then updates it again within the next 10 seconds, the module assumes that the first was a mistake, and overwrites the older status with the newer one. However, a bug allowed one user's message to overwrite a second user's status if posted within 10 seconds of the second user having updated her status. -------- VERSIONS AFFECTED --------------------------------------------------- * Facebook-style Statuses (Microblog) 6.x-2.x prior to 6.x-2.1 Drupal core is not affected. If you do not use the contributed Facebook-style Statuses (Microblog) module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use Facebook-style Statuses (Microblog) for Drupal 6.x upgrade to Facebook-style Statuses (Microblog) 6.x-2.1 [1] See also the Facebook-style Statuses (Microblog) project page [2]. -------- REPORTED BY --------------------------------------------------------- * Hiroaki [3] -------- FIXED BY ------------------------------------------------------------ * Isaac Sukin (IceCreamYou [4]), the module maintainer. -------- CONTACT ------------------------------------------------------------- The security contact for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact.
