For more information, please refer to the ABB Cybersecurity Advisory.

ABB recommends the following general security practices for any installation of software-related ABB products:

• Isolate special purpose networks (e.g. for automation systems) and remote devices behind firewalls and separate them from any general-purpose network (e.g. office or home networks).
• Install physical controls so no unauthorized personnel can access your devices, components, peripheral equipment, and networks.
• Never connect programming software or computers containing programing software to any network
  other than the network for the devices that it is intended for.
• Scan all data imported into your environment before use to detect potential malware infections.
• Minimize network exposure for all applications and endpoints to ensure that they are not accessible from the Internet unless they are designed for such exposure and the intended use requires such.
• Ensure all nodes are always up to date in terms of installed software, operating system, and firmware patches as well as anti-virus and firewall.
• 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

Cityworks has released the following update guidance for users:

• Trimble will be releasing updated versions to both 15.x (15.8.9 available January 28, 2025) and Cityworks 23.x software releases (23.10 available January 29, 2025). Information on the updated versions will be available through the normal channels via the Cityworks Support Portal(Login required). On-premises users should install the updated version immediately. These updates will be automatically applied to all Cityworks Online (CWOL) deployments.
• Trimble has observed that some on-premises deployments may have overprivileged Internet Information Services (IIS) identity permissions. For avoidance of doubt, and in accordance with Trimble’s technical documentation, IIS should not be run with local or domain level administrative privileges on any site. Please refer to the direction in the latest release notes in the Cityworks Support Portal(Login required) for more information on how to update IIS identity permissions. Trimble’s CWOL customers have their IIS identity permissions set appropriately and do not need to take this action.
• Trimble has observed that some deployments have inappropriate attachment directory configurations. Trimble recommends that attachment directory root configuration should be limited to folders/subfolders which only contain attachments. Please refer to the direction in the latest release notes in the Cityworks Support Portal(Login required) for more information on how to ensure proper configuration of the attachment directory.

BMXNOR0200H: Version SV1.70IR26 of BMXNOR0200H includes a fix for this vulnerability and is available for download.

Users should use appropriate patching methodologies when applying these patches to their systems. Schneider Electric strongly recommends the use of back-ups and evaluating the impact of these patches in a testing and development environment, or on an offline infrastructure. Contact Schneider Electric’s Customer Care Center for assistance removing a patch.

Schneider Electric is establishing a remediation plan for all future versions of Modicon M340 processors BMXP34*, BMXNOE0100 and BMXNOE0110 that will include a fix for this vulnerability. They will provide an update when the remediation is available. Until then, users should immediately apply the following mitigations to reduce the risk of exploit:

• Set up network segmentation and implement a firewall to block all unauthorized access to FTP Port 21/TCP on the devices.
• Disable FTP service via EcoStruxureTM Control Expert. This is disabled by default when a new application is created.
• Disable Web server service via EcoStruxureTM Control Expert. This is disabled by default when a new application is created.
• Configure the Access Control List following the recommendation on the “Modicon Controllers System Cybersecurity”

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

AutomationDirect recommends that users update C-MORE EA9 HMI software and firmware to V6.80.

If an immediate update is not feasible, AutomationDirect recommends considering the following interim steps until the programming software can be updated:

• Isolate the HMI Workstation: Disconnect the HMI from external networks (e.g., internet or corporate LAN) to limit exposure to external threats.
• Use dedicated, secure internal networks or air-gapped systems for communication with programmable devices.
• Control Access: Restrict physical and logical access to the HMI to authorized personnel only.
• Implement Whitelisting: Use application whitelisting to allow only pre-approved and trusted software to execute on the HMI. Block untrusted or unauthorized applications.
• Apply Endpoint Security Measures: Use antivirus or endpoint detection and response (EDR) tools to monitor for and mitigate threats. Ensure that host-based firewalls are properly configured to block unauthorized access.
• Monitor and Log Activity: Enable logging and monitoring of system activities to detect potential anomalies or unauthorized actions. Regularly review logs for suspicious activity.
• Use Secure Backup and Recovery: Regularly back up the workstation and its configurations to a secure location. Test recovery procedures to ensure minimal downtime in the event of an incident.
• Conduct Regular Risk Assessments: Continuously assess the risks posed by the outdated software and adjust mitigation measures as necessary.

For more information, please see the AutomationDirect security advisory.

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

• 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.
