In January 2026, Rockwell Automation disclosed multiple vulnerabilities in its ArmorStart® LT motor control devices, specifically models 290D, 291D, and 294D up to and including version V2.002. These vulnerabilities, identified as CVE-2025-9464 through CVE-2025-9283, can lead to denial-of-service conditions. Exploitation methods include fuzzing of CIP classes, execution of Achilles Comprehensive grammar tests, and active scanning with tools like Burp Suite, causing devices to become unresponsive or reboot unexpectedly.
