(CVE-2016-10012) Impact A locally authenticated attacker may be able to exploit this vulnerability and gain elevated privileges. Security Advisory Status F5 Product Development has assigned ID 637629 (BIG-IP, BIG-IQ, Enterprise Manager, and F5 iWorkflow) and INSTALLER-2868 (Traffix SDC) to this vulnerability. Additionally, F5 iHealth may list Heuristic H62201745 on the Diagnostics > Identified > Low page.

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. Mitigation To mitigate this vulnerability for affected F5 products, you should permit management access over a secure network and limit secure shell (SSH) access to only trusted users. For more information about securing access to BIG-IP systems, refer to K13309: Restricting access to the Configuration utility by source IP address (11.x - 15.x) and K13092: Overview of securing access to the BIG-IP system.
