Risk Summary

Successful exploitation of these vulnerabilities could create a denial-of-service condition or allow for remote code execution.

Remediations

  • Disable the web server, if possible (This component is an optional feature and disabling it will not disrupt the intended use of the device)
  • Configure firewalls to disallow network communication through HTTP/Port 802
  • Upgrade to the MicroLogix 800 or MicroLogix 850 as this device does not have the web server component
  • Rockwell Automation also recommends users to employ cybersecurity best practices, as outlined in their Knowledgebase article.
