The authentication mechanism on affected systems does not provide a sufficient level of protection against unauthorized configuration changes. Primary operations, namely turning the cooling unit on and off and setting the temperature set point, can be modified without authentication.
The authentication mechanism on affected systems is configured using hard-coded credentials. These credentials could allow attackers to influence the primary operations of the affected systems, namely turning the cooling unit on and off and setting the temperature set point.
