Unauthenticated CLI access via socket race
Published Dec 22, 2021 · Updated Aug 3, 2024
Authentication bypass in Garrett Metal Detectors iC Module CMA 5.0 allows remote attackers to hijack authenticated CLI sessions. The server copies the most recently accepted socket into the authenticated thread instead of the socket whose password passed validation. A connection arriving during the roughly 0.5-second login window can replace the legitimate socket and gain plaintext CLI access to monitor statistics or change detector configuration.
