4. MITIGATIONS

Schneider Electric recommends for users to immediately apply the following mitigations to reduce the risk of exploit:

• Use HMI only in a protected environment to minimize network exposure and ensure that they are not accessible from public Internet or untrusted networks.
• Setup network segmentation and implement a firewall to block all unauthorized access.
• Restrict usage of unverifiable portable media.
• Restricting the application access to limit the transfer of Firmware to HMIScanning of software/files for rootkits before usage and verifying the digital signature.
• When exchanging files over the network, use secure communication protocols.

For users to be informed of all updates, including details on affected products and remediation plans, subscribe to Schneider Electric’s security notification service here:
https://www.se.com/ww/en/work/support/cybersecurity/notification-contact.jsp

Schneider Electric strongly recommend the following industry cybersecurity best practices:

• Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
• Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
• Place all controllers in locked cabinets and never leave them in the “Program” mode.
• Never connect programming software to any network other than the network intended for that device.
• Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks.
• Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation.
• Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet.
• When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

4. MITIGATIONS

Hitachi Energy has identified the following specific workarounds and mitigations users can apply to reduce risk:

• Update to Version 8.9.6 or later when available
• Hitachi Energy recommends users implement countermeasures for DoS with proper firewall rule sets and filters, as well as to apply mitigation as described in the Mitigation Factors/Workarounds
  Section.

Hitachi Energy recommends users follow recommended security practices and firewall configurations, which can help protect a process control network from attacks that originate from outside the network. Such practices include that process control systems are physically protected from direct access by unauthorized personnel, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed, and others that have to be evaluated case by case. Process control systems should not be used for Internet surfing, instant messaging, or receiving e-mails. Portable computers and removable storage media should be carefully scanned for viruses before they are connected to a control system.

4. MITIGATIONS

Schneider Electric is establishing a remediation plan for all future versions of Modicon M241/M251/M258/LMC058 that will include a fix for this vulnerability. They will update SEVD-2024-345-03 when the remediation is available. Until then, users should immediately apply the following mitigations to reduce the risk of exploit:

• Use controllers and devices only in a protected environment to minimize network exposure and ensure that they are not accessible from public internet or untrusted networks.
• Filter ports and IP through the embedded firewall.
• Setup network segmentation and implement a firewall to block all unauthorized access to Port 502/TCP.
• Disable all unused protocols (default configuration).
• For more details refer to “Cybersecurity Guidelines for EcoStruxure Machine Expert, Modicon and PacDrive Controllers and Associated Equipment Guide”

To ensure users are informed of all updates, including details on affected products and remediation plans, Schneider Electric recommends subscription to their security notification service.

Schneider Electric strongly recommends the following industry cybersecurity best practices:

• Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
• Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
• Place all controllers in locked cabinets and never leave them in the “Program” mode.
• Never connect programming software to any network other than the network intended for that device.
• Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks.
• Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation.
• Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet.
• When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

4. MITIGATIONS

Delta Electronics recommends users update DTM Soft to version 1.60.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:

• Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
• Locate control system networks and remote devices behind firewalls and isolating them from business networks.
• When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time. This vulnerability is not exploitable remotely.
