Description
This module exploits a php unserialize() vulnerability in Horde <= 5.1.1 which could be abused to allow unauthenticated users to execute arbitrary code with the permissions of the web server. The dangerous unserialize() exists in the 'lib/Horde/Variables.php' file. The exploit abuses the __destruct() method from the Horde_Kolab_Server_Decorator_Clean class to reach a dangerous call_user_func() call in the Horde_Prefs class.
