[Security-news] SA-CONTRIB-2010-020 - Facebook-style Statuses (Microblog) - Access bypass

[security-news at drupal.org]

  * 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.
