CAMS for HIS Server contained in the following Yokogawa Electric products improperly authenticate the receiving packets. The authentication may be bypassed via some crafted packets: CENTUM CS 3000 versions from R3.08.10 to R3.09.00, CENTUM VP versions from R4.01.00 to R4.03.00, from R5.01.00 to R5.04.20, and from R6.01.00 to R6.08.00, and Exaopc versions from R3.72.00 to R3.79.00.
The authentication scheme or implementation uses key data elements that are assumed to be immutable, but can be controlled or modified by the attacker.
