cip over ethernet ip

Discussions on WindowsForum.com about CIP over EtherNet/IP focus on security vulnerabilities in Rockwell Automation controllers that use the Common Industrial Protocol (CIP) over EtherNet/IP. A key topic is CVE-2025-9124, a denial-of-service flaw in the Compact GuardLogix 5370 PAC. This vulnerability can be exploited by sending a crafted CIP unconnected explicit message, causing a major non-recoverable fault that requires manual recovery and program reloads. The forum emphasizes the urgency of applying firmware updates to mitigate such risks in industrial control systems. These threads are relevant for IT and OT professionals managing Windows-based engineering workstations and Rockwell automation environments.
