If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Versions known to be not vulnerable column. 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.

To determine the necessary upgrade path for your BIG-IQ system, you should understand the BIG-IQ product offering name changes. For more information, refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow systems.

Mitigation

To mitigate this vulnerability, you should permit management access to F5 products only over a secure network and limit shell access to only 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.
