CVE-2025-8008

Device crash via crafted Forward Close messages

Published Sep 9, 2025 · Updated Sep 9, 2025

Denial of service in Rockwell Automation EN4TR devices through 6.001 allows remote attackers to crash the device with crafted messages. Protected-mode Forward Close processing fails to handle a specifically crafted message as an exceptional condition and terminates the device. The attack requires adjacent-network access, needs no authentication or user interaction, and interrupts device availability.
