Fortinet is aware of a threat actor creating a malicious file from previously exploited Fortinet vulnerabilities (CVE-2024-21762, CVE-2023-27997, and CVE-2022-42475) within FortiGate products. This malicious file could enable read-only access to files on the device’s file system, which may include configurations. Fortinet has communicated directly with the account holders of customers identified as impacted by this issue based on the available telemetry with mitigation guidance.

See the following resource for more information:

• Analysis of Threat Actor Activity | Fortinet Blog

CISA encourages administrators to review Fortinet’s advisory and:

• Upgrade to FortiOS versions 7.6.2, 7.4.7, 7.2.11, 7.0.17, 6.4.16 to remove the malicious file and prevent re-compromise.
• Review the configuration of all in-scope devices.
• Reset potentially exposed credentials.
• As a work-around mitigation until the patch is applied, consider disabling SSL-VPN functionality, as exploitation of the file requires the SSL-VPN to be enabled.

3.4 RESEARCHER

ABB reported these vulnerabilities to CISA.

4. MITIGATIONS

ABB recommends users to perform the following actions at their earliest convenience:

• Modem module vulnerability mitigations: Mitigate the cellular module vulnerabilities by contacting the mobile network operator and requesting to disable binary SMS for a mobile subscription. Note that binary SMS service is often disabled by default based on operator restrictions. If SMS services are not used in the solution, consider disabling them completely.
• SSH vulnerability mitigations: Establish remote connections through OpenVPN. If the SSH protocol is used for remote administration of Arctic wireless gateway, it is to be considered logging in to the wireless gateway through an OpenVPN tunnel. Do not expose SSH port to public networks. Keep the SSH port closed to public networks and thus limit the number of potential attackers who can attempt to exploit the vulnerability. This way only devices within the private network or those connected through a secure VPN can access the SSH server.
• Common mitigations: Obtain a private cellular access point to limit impact of any potential exploit. Contact the cellular provider for availability. Restrict physical access to the product. Follow general security recommendations for further advice on how to keep the system secure.

For more information, please refer to ABB’s Cybersecurity Advisory 2NGA002427.

ABB strongly recommends the following (non-exhaustive) list of cyber 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 the 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.

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

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov 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.

3.4 RESEARCHER

ABB PSIRT reported these vulnerabilities to CISA.

4. MITIGATIONS

If the drive or power controller is in an exploitable configuration, ABB recommends immediately applying the mitigations described in the workarounds section of the ABB security advisory.

For more information, see ABB’s security advisory.

ABB strongly recommends the following (non-exhaustive) list of general cyber security practices for any installation of software-related 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.
• 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). Also, understand that VPNs are only as secure as the connected devices.

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

CISA also recommends users take the following measures to protect themselves from social engineering attacks:

• Do not click web links or open attachments in unsolicited email messages.
• Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
• Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
