Technical details
The vulnerability is improper TLS certificate validation in Eaton easySoft when communicating with easyE4 devices. An attacker positioned on the adjacent network can perform a man-in-the-middle attack by presenting a fraudulent certificate that easySoft will accept due to insufficient validation checks. This allows interception and modification of traffic between the management software and controlled devices.
