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, do not configure NTP to use the Autokey security protocol for authentication operations.
