Attackers in a privileged network position may be able to launch a man-in-the-middle attack against these connections. TAC databases are used in BIG-IP PEM for Device Type and OS (DTOS) and Tethering detection. Customers not using BIG-IP PEM, not configuring downloads of TAC database files, or not using HTTP for that download are not affected. (CVE-2017-6144) Impact This vulnerability allows data tampering or unauthorized information disclosure. Security Advisory Status F5 Product Development has assigned ID 627916 (BIG-IP) to this vulnerability. Additionally, BIG-IP iHealth may list Heuristic H81601350 on the Diagnostics > Identified > Medium 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. Mitigation To mitigate this issue, ensure the network used for connections between the BIG-IP system and the TAC database host server is secure from unauthorized intrusion.
