2NGA002743 — ABB AbilityTM zenon Remote Transport Vulnerability

The vulnerability enables unauthorized access to the Reboot OS function within the Remote Transport Service, allowing an attacker to trigger a system reboot without the required authentication. This functionality initiates a system reboot on the target machine. However, remote exploitation of this vulnerability is not feasible unless the attacker has already gained access to the network where the affected ABB Ability™ zenon system is deployed.

At the time of writing, there is no evidence that this vulnerability is being actively exploited in the wild.
