CVE-2025-7353Network attack vector

Unauthenticated code execution via enabled debugger agent

Published Aug 14, 2025 · Updated Feb 26, 2026

Remote code execution in Rockwell Automation ControlLogix Ethernet modules 11.004 and earlier allows remote attackers to control execution flow. An enabled web-based debugger agent accepts connections directed to a specific IP address and exposes memory-dump and memory-modification functions. No authentication or user interaction is required, so network-reachable attackers can read or alter device memory and redirect code execution.
