Detailsinfo

A vulnerability was found in Rockwell MicroLogix 1400 Controller and 1756 ControlLogix Communications Module (version now known). It has been classified as critical. This affects some unknown processing of the component CIP Connection Request Handler. The manipulation with an unknown input leads to a missing authentication vulnerability (IP Address). CWE is classifying the issue as CWE-306. The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Rockwell Automation MicroLogix 1400 Controllers and 1756 ControlLogix Communications Modules An unauthenticated, remote threat actor could send a CIP connection request to an affected device, and upon successful connection, send a new IP configuration to the affected device even if the controller in the system is set to Hard RUN mode. When the affected device accepts this new IP configuration, a loss of communication occurs between the device and the rest of the system as the system traffic is still attempting to communicate with the device via the overwritten IP address.
