Description
Active debug code exists in OMRON CP1L-EL20DR-D all versions, which may lead to a command that is not specified in FINS protocol being executed without authentication. A remote unauthenticated attacker may read/write in arbitrary area of the device memory, which may lead to overwriting the firmware, causing a denial-of-service (DoS) condition, and/or arbitrary code execution.
