DoS via unexpected reboot in Rockwell Automation ArmorStart LT (Achilles Comprehensive limited storm tests)

IdentifiersCVE-2025-9282CWE-400· Uncontrolled Resource Consumption

A denial-of-service vulnerability in Rockwell Automation ArmorStart® LT where network-based protocol test traffic (specifically Achilles Comprehensive limited storm tests) can trigger an unexpected device reboot. The reboot causes a temporary outage of the Link State Monitor for several seconds, resulting in loss of availability.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Remote attackers can induce a denial-of-service condition by causing the ArmorStart LT device to reboot, temporarily taking the Link State Monitor down for several seconds and disrupting availability of the affected device/functionality.

Mitigation

If you can’t patch tonight, do this now.

Minimize network exposure of control system devices; ensure they are not accessible from the internet; place control system networks/remote devices behind firewalls and isolate them from business networks; use secure remote access methods (e.g., VPN) and keep them updated; perform impact analysis and risk assessment prior to deploying defensive measures.

Remediation

Patch, then assume compromise.
