Security Advisory Recommended Actions

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.

Mitigation

To mitigate this vulnerability, you should permit access to the Configuration
utility only over a secure network and limit login access to trusted users.

For more information, refer to:

  o K13092: Overview of securing access to the BIG-IP system
  o K13309: Restricting access to the Configuration utility by source IP
    address (11.x - 15.x)
