Project modification via Trusted Slot bypass
Published Aug 1, 2024 · Updated Sep 25, 2025
Authorization bypass in Rockwell Automation Logix devices allows remote authenticated users to modify controller projects and configuration. An affected 1756 chassis module accepts CIP commands through an alternate channel that bypasses the controller's Trusted Slot restriction. Network access with low privileges and an affected module in the chassis is required; exploitation changes user projects or device configuration.
