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 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.
