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.

For more information refer to the Schneider Electric recommended cybersecurity best practices document.

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/WorkaroundsSection.

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.

3.4 RESEARCHER

Vera Mens of Claroty Research – Team82 reported these vulnerabilities to Rockwell Automation.

4. MITIGATIONS

Rockwell Automation has corrected these problems in firmware revision 4.020 and recommends users upgrade to the latest version available.

Rockwell Automation encourages users of the affected software who are not able to upgrade to one of the corrected versions to apply security best practices, where possible.

For more information, see Rockwell Automation’s security advisory.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, 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.

 ​Today, CISA—through the Joint Cyber Defense Collaborative and in coordination with the Office of the National Cyber Director (ONCD)—released the National Cyber Incident Response Plan Update Public Comment Draft. The draft requests public comment on the National Cyber Incident Response Plan (NCIRP)—public comment period begins today and concludes on January 15, 2025. Since initial publication in 2016, CISA conducted broad and extensive engagement and information exchanges with public and private sector partners, interagency partners, federal Sector Risk Management Agencies (SRMAs), and regulators to build upon the successes of the inaugural NCIRP. The draft NCIRP update describes a national approach to coordinating significant cyber incident detection and response. The draft update considers the evolution in the cyber threat landscape and lessons learned from historical incidents. The text also addresses the vital role that the private sector, state and local governments (including tribal and territorial), and federal agencies hold in responding to cyber incidents.CISA is seeking more perspectives to help strengthen the NCIRP and invites stakeholders from across the public and private sectors to share their knowledge and experiences, further informing our findings and contributing to this revision. Public comments may be posted via the Federal Register.

 ​Today, CISA and the Environmental Protection Agency (EPA) released Internet-Exposed HMIs Pose Cybersecurity Risks to Water and Wastewater Systems. This joint fact sheet provides Water and Wastewater Systems (WWS) facilities with recommendations for limiting the exposure of Human Machine Interfaces (HMIs) and securing them against malicious cyber activity.
HMIs enable operational technology owners and operators to read supervisory control and data acquisition systems connected to programmable logic controllers. Threat actors can exploit exposed HMIs at WWS Sector utilities without cybersecurity controls, resulting in operational impacts and forcing victims to revert to manual operations (see Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity).
EPA and CISA strongly encourage WWS Sector organizations review and implement the mitigations in this fact sheet to harden remote access to HMIs. Visit our Water and Wastewater Systems page for additional resources to help protect the WWS Sector.
