Security-boundary bypass via external monitor
Published Oct 10, 2023 · Updated Sep 18, 2024
Privilege bypass in F5 BIG-IP allows remote authenticated users with the Administrator role to cross an Appliance mode security boundary. The external-monitor path accepts an Administrator-controlled action without enforcing the restriction that blocks root-level Bash access; F5 has not disclosed lower-level implementation details. Exploitation requires Appliance mode and an Administrator account, and the published impact is bounded to confidentiality and integrity across that boundary without service interruption.
