This service does not properly re-validate cookies when making that conversion, allowing once-valid but now expired cookies to be converted to valid tokens. (CVE-2017-6145) Impact An attacker with an expired BIG-IP authentication cookie can use it to get valid iControl REST authentication tokens in order to gain access to the iControl REST interface of the BIG-IP system. Security Advisory Status F5 Product Development has assigned ID 641445 (BIG-IP) to this vulnerability. Additionally, BIG-IP iHealth may list Heuristic H22317030 on the Diagnostics > Identified > High screen.

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. 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. Mitigation To mitigate this vulnerability, you should permit management access to F5 products only over a secure network and restrict command line access for affected systems to trusted users. For more information, refer to K13309: Restricting access to the Configuration utility by source IP address (11.x - 13.x) and K13092: Overview of securing access to the BIG-IP system.
