Mitigation Strategies

Immediate mitigation steps include following security best practices recommended by Rockwell Automation and contacting their TechConnect support for guidance. Since no corrected software version is currently available, applying any provided workarounds from Rockwell Automation is advised. Monitoring system stability and avoiding input of invalid values into COM methods within the ArmorStart Classic AOP can help reduce risk. [1]

Executive Summary

This vulnerability is a high-severity denial-of-service (DoS) issue in the ArmorStart Add-On Profile (AOP) used with the Studio 5000 Logix Designer for ArmorStart Classic distributed motor controllers. It occurs because invalid input values passed to Component Object Model (COM) methods cause uncaught exceptions, which make the system unresponsive. [1]
