^1 The CVSSv3 score link takes you to a resource outside of AskF5, and it is
possible that the document may be removed without our knowledge.

^2 The specified products contain the affected code. However, F5 identifies the
vulnerability status as Not vulnerable because the attacker cannot exploit the
code in default, standard, or recommended configurations.

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

BIG-IP, BIG-IQ, iWorkflow, and Enterprise Manager

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 trusted users. For more information, refer to one or more
of these articles:

  * K13309: Restricting access to the Configuration utility by source IP
    address (11.x - 13.x)
  * K13092: Overview of securing access to the BIG-IP system
  * K31401771: Restricting access to the BIG-IQ or F5 iWorkflow user interface
    by source IP address
