1 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.

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 Versions known to be not vulnerable 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 ensure that the role map immediately reloads after you modify the user privileges by restarting the restjavad process. To do so, perform the following procedure:

Impact of procedure: Running the following command will temporarily interrupt iControl while the process reloads, but will not otherwise impact traffic processing on the BIG-IP system.

  1. Log in to the TMOS Shell (tmsh) by typing the following command:

tmsh

  1. Restart the restjavad process by typing the following command:

restart /sys service restjavad
