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

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 can license the BIG-IP system to operate in Appliance mode. The underlying vulnerability will continue to exist; however, an attacker cannot force arbitrary system commands because bash access is disabled in Appliance mode. For information about Appliance mode, refer to K12815: Overview of Appliance mode.

Impact of action: Appliance mode is designed for customers in especially sensitive sectors by limiting the BIG-IP system administrative access to match that of a typical network appliance and not a multi-user UNIX device. When a BIG-IP system is configured in Appliance mode, the bash access to the file system is restricted. For information about the impacts of licensing the BIG-IP system to operate in Appliance mode, refer to K12815: Overview of Appliance mode.
