If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. Mitigation To mitigate this vulnerability, you should permit management access to F5 products only over a secure network and restrict command line access for affected systems to the trusted users. For more information, refer to K13309: Restricting access to the Configuration utility by source IP address (11.x - 13.x) and K13092: Overview of securing access to the BIG-IP system.
