4. MITIGATIONS

Ruijie reports that the issues have been fixed on the cloud and no action is needed by end users. However, 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.

4. MITIGATIONS

Schneider has provided the following remediations:

• Users should consider blocking HTTP access to the device at the firewall level or disable the HTTP web service to reduce the risk of exposure.
• Version 2.8.3 of the PowerLogic PM5560, 5563, 5580 firmware includes fixes for these vulnerabilities.

• PowerLogic PM8ECC has reached end of service and is no longer supported.

Schneider Electric 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.

To make the fix effective for existing CODESYS projects, the user also must adjust the version of the OSCAT Basic library to be used in the Library Manager of the CODESYS project to Version 3.3.5.0. Then the user must update the CODESYS application on the PLC by download or online change and rebuild/download the boot application.

Without an update, the vulnerability can be prevented by validating all values in the PLC program before they are passed to the affected function. In particular, negative values must be blocked as function parameters of MONTH_TO_STRING.

Regardless of whether the OSCAT Basic library in the programming system was updated or the security vulnerability in the PLC program was mitigated, a download or online change must be performed to update the application on the PLC. CODESYS reminds users to rebuild/download the boot project.

For more information see the associated CERT@VDE security advisory.

For a list of system environments the library has been validated against see OSCAT's library documentation.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. 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.

General Security Recommendations
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.

4. MITIGATIONS

Schneider Electric has identified the following remediations users can apply to reduce risk:

• PowerLogic PM5320: Version 2.4.0 of PowerLogic PM5320 includes a fix for this vulnerability.
• PowerLogic PM5340: Version 2.4.0 of PowerLogic PM5340 includes a fix for this vulnerability.

If users choose not to apply the remediation provided above, Schneider Electric recommends immediately applying the following steps to reduce the risk of exploitation:

1. Enable IGMP Snooping: Ensure that IGMP Snooping is enabled on the switch. This feature allows the switch to intelligently forward multicast traffic only to the necessary ports where interested hosts reside. It prevents unnecessary flooding of multicast traffic across all ports, thereby enhancing network efficiency and minimizing unnecessary load on network resources.
2. Configure VLAN Interface Settings: Set up VLAN interface settings on the switch. It's important to have distinct configurations for each VLAN to ensure proper IGMP operation.
3. Multicast Filtering: Use IGMP filtering to control the propagation of IGMP traffic through the network. This involves configuring filters on a switch virtual interface (SVI), per-port, or per-port per-VLAN basis. Multicast filtering helps manage IGMP snooping and controls multicast traffic forwarding effectively.

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.

3.4 RESEARCHER

Dimitri Lesy and Florens Schneider reported this vulnerability to Siemens.

4. MITIGATIONS

Siemens has identified the following specific workarounds and mitigations that users can apply to reduce the risk:

• Spectrum Power 7: Update to V24Q3 or later version

Operators of critical power systems (e.g. TSOs or DSOs) worldwide are usually required by regulations to build resilience into the power grids by applying multi-level redundant secondary protection schemes. Siemens recommends that the operators check whether appropriate resilient protection measures are in place. The risk of cyber incidents impacting the grid's reliability can thus be minimized by virtue of the grid design. Siemens strongly recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product. If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment. As a general security measure, Siemens strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN). It is advised to configure the environment according to Siemens' operational guidelines in order to run the devices in a protected IT environment.
