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.

Note: For details about how Security Advisory articles are versioned, and what
versions are listed in the table, refer to K51812227: Understanding Security
Advisory versioning.

To determine the necessary upgrade path for your BIG-IQ system, you should
understand the BIG-IQ product offering name changes. For more information,
refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow systems


To mitigate this vulnerability, you can refrain from using the Access Manager
role when creating user accounts on the BIG-IQ system. In addition, you can
change any existing user accounts on the system that are assigned the Access
Manager role to use a different access role.
