Executive Summary

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.

Cloud Native Security Fabric Mitigations and ControlsCNSF

Aviatrix Zero Trust CNSF is relevant to this incident as it can limit the attacker's ability to exploit vulnerabilities in the ArmorStart® LT device by enforcing strict segmentation and identity-aware routing, thereby reducing the blast radius of such attacks.

Initial Compromise

Control: Cloud Native Security Fabric (CNSF)

Mitigation: Aviatrix Zero Trust CNSF would likely limit the attacker's ability to exploit the device by enforcing strict segmentation and identity-aware routing.

Privilege Escalation

Control: Zero Trust Segmentation

Mitigation: Aviatrix Zero Trust Segmentation would likely limit the attacker's ability to escalate privileges by enforcing strict access controls and segmentation.

Lateral Movement

Control: East-West Traffic Security

Mitigation: Aviatrix East-West Traffic Security would likely limit the attacker's ability to move laterally by enforcing strict segmentation and identity-aware routing.

Command & Control

Control: Multicloud Visibility & Control

Mitigation: Aviatrix Multicloud Visibility & Control would likely limit the attacker's ability to establish command and control channels by providing continuous visibility and control across multicloud environments.

Exfiltration

Control: Egress Security & Policy Enforcement

Mitigation: Aviatrix Egress Security & Policy Enforcement would likely limit the attacker's ability to exfiltrate data by enforcing strict egress policies and monitoring outbound traffic.

Impact (Mitigations)

Aviatrix Zero Trust CNSF would likely limit the impact of such attacks by enforcing strict segmentation and identity-aware routing, thereby reducing the blast radius of such attacks.
