SYSTEM code execution via replaceable CAMS DLL
Published Jun 17, 2024 · Updated Aug 1, 2024
DLL hijacking in Yokogawa CENTUM CS 3000 and CENTUM VP allows remote authenticated users to execute programs as SYSTEM. The CAMS Log Server relies on a DLL that users able to enter the host or access its shared folder can replace, after which the server loads the tampered library with SYSTEM authority. Affected releases are CENTUM CS 3000 R3.08.10 through R3.09.50 and CENTUM VP R4.01.00 through R4.03.00, R5.01.00 through R5.04.20, and R6.01.00 through R6.11.10; the standard operation and monitoring function is exposed even when CAMS is disabled.
