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 only trusted users. For more information about restricting access to the BIG-IP and Enterprise Manager systems, refer to K13092: Overview of securing access to the BIG-IP system.
