Rockwell Automation FactoryTalk Linx and FactoryTalk Services Platform

CVSS 7.5 HIGH

Risk Summary

Successful exploitation of these vulnerabilities may result in denial-of-service conditions.

Remediations

  • Rockwell Automation published PN1540 to inform users of the risk of these vulnerabilities and instruct users on the proper use of patches.
  • Utilize proper network infrastructure controls, such as firewalls, to help ensure traffic from unauthorized sources is blocked.
  • Consult the product documentation for specific features, such as a hardware keyswitch setting, which may be used to block unauthorized changes, etc.
  • Block all traffic to EtherNet/IP or other CIP protocol-based devices from outside the manufacturing zone by blocking or restricting access to TCP and UDP Port 2222 and Port 44818 using proper network infrastructure controls, such as firewalls, UTM devices, or other security appliances. For more information on TCP/UDP ports used by Rockwell Automation products, see Knowledgebase Article ID BF7490.
  • Run all software as a User, not as an Administrator, to minimize the impact of malicious code on the infected system.
  • Use Microsoft AppLocker or other similar allow list applications to help mitigate risk. Information on using AppLocker with Rockwell Automation products is available at Knowledgebase Article ID QA17329.
  • Confirm the least-privilege user principle is followed and the user/service account access to shared resources (such as a database) is only granted with a minimum number of rights as needed.
  • Do not open untrusted .ftd files with FactoryTalk Services Platform.
  • Do not click on or open URL links from untrusted sources.
  • Employ training and awareness programs to educate users on the warning signs of a phishing or social engineering attack.
  • Use trusted software, software patches, antivirus/antimalware programs and interact only with trusted websites and attachments.
  • Minimize network exposure for all control system devices and/or systems and ensure they are not accessible from the Internet. For further information about the risks of unprotected Internet accessible control systems, please see Knowledgebase Article ID PN715.
  • Locate control system networks and devices behind firewalls and isolate them from the business network.
  • When remote access is required, use secure methods, such as virtual private networks (VPNs), and recognize VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize a VPN is only as secure as the connected devices.
