1The CVSSv3 score link takes you to a resource outside of AskF5, and it is possible that the document may be removed without our knowledge.
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 Fixes introduced in 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 mitigate this vulnerability, you can secure the network failover VLAN so that only trusted users have physical and network access to the VLAN, or enable the failover.secure database variable. For more information on enabling the failover.secure database variable, refer to K90231443: Configuring secure network failover traffic
