^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 In BIG-IP 13.1.0 and later, you can update APM client components
independently from BIG-IP software. APM Clients 7.1.5, which is bundled with

vulnerability, customers running BIG-IP 13.1.0 and later can download and
install APM Clients 7.1.7.


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

None
