A vulnerability exists in Rockwell Automation affected products that allows a threat actor to bypass the Trusted® Slot feature in a ControlLogix® controller. If exploited on any affected module in a 1756 chassis, a threat actor could potentially execute CIP commands that modify user projects and/or device configuration on a Logix controller in the chassis.
