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.


To mitigate this vulnerability, you should permit connectivity access to the
affected F5 products only over a secure network and restrict access for the
affected systems to only trusted users. For more information, refer to one or
more of these articles:

  o K13309: Restricting access to the Configuration utility by source IP
    address (11.x - 14.x)
  o K13092: Overview of securing access to the BIG-IP system
  o K31401771: Restricting access to the BIG-IQ or F5 iWorkflow user interface
    by source IP address
