Hardcoded password vulnerability in Yokogawa CENTUM VP allows authentication bypass for the PROG system account across versions R5.01.00-R5.04.20, R6.01.00-R6.12.00, and R7.01.00. An attacker who obtains the hardcoded credential and has direct access to the Human Interface Station (HIS) running CTM authentication mode can log in as PROG; however, real-world risk is constrained because PROG defaults to S1 (OFFUSER) permission level, and exploitation requires pre-existing HIS access. No public exploit code or active CISA KEV status identified at time of analysis.
