* 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 ---------------------------------------------------
