Evidence used

  • No CISA KEV confirmation is currently recorded.
  • A structured source references public exploit or proof-of-concept material.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 5.19% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs AMD Ryzen™ 3000 Series Desktop Processors “Matisse” AM4 and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Cross-source reconciliation

Remediation availability differs by product scope

Verified remediation exists for at least one product or source, but 14 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Distribution package intelligence

Release-specific package status

Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.

9 package states
Package result overrides the generic status

BlackTree has verified remediation for at least one product or source, but the relevant distribution still reports no fixed package for 1 affected package state shown here. Treat those rows as affected with no fix until that distribution publishes a fixed version.

Repository candidate not checked

A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

  • ABB M2M Gateway ARM600, firmware versions >=4.1.2|<=5.0.3
  • ABB M2M Gateway SW, software versions >=5.0.1|<=5.0.3
Summary
Cross-Process Information Leak in certain AMD processors. This could lead to an attacker potentially accessing confidential information. Note: ARM600 servers utilize Intel processors, but there may be ARM600 SW installations running in AMD processor environments.
Remediation
Mitigating factors describe conditions and circumstances that make an attack that exploits the vulnerability difficult or less likely to succeed. The following mitigations are recommended. 1. Obtain a cellular private access point (APN). A dedicated private cellular access point and respective SIM card subscriptions can be requested from your cellular service provider. This service doesn’t expose the traffic between remote sites and main site to the internet but rather uses cellular operator’s private wide area network (WAN). Therefore, the ARM600 wouldn’t need open ports to the internet. 2. Avoid exposing any system component to the internet. If, however, the ARM600 is exposed to the internet, only the VPN port should be opened towards the internet (e.g., Patrol management connections can be configured to use VPN tunnel and remote administration connections can be implemented by using OpenVPN PC-client). 4. Perform firewall configuration by the "allowlisting" principle, i.e., explicitly allowing only the required ports and protocols and blocking any other traffic. 6. If the internet is used as a WAN media for carrying VPN tunnels, use Demilitarized Zone (DMZ) for terminating connections from the internet (i.e., the remote connections should terminate to the DMZ network, which would be segregated from other networks by a firewall. The ARM600 server would be located into this DMZ). 7. Change the default user credentials of ARM600 and Arctic wireless gateways into non-defaults and use complex non-guessable passwords with special characters. Do not reuse passwords within the system. 8. Use administrator (i.e., root user) privileges only when required by the task. 9. Supporting systems, such as PCs used for configuration, should be frequently updated. If possible, use dedicated site PCs for upgrading and engineering purposes. At minimum, PCs should be investigated by running a full virus scan with recently updated signature files before introducing the PC to the OT system. Any data, such as device configurations and firmware update files transferred to the Arctic system should be virus scanned prior to transferring. 10. Introduce a backup policy, which will ensure periodical backups and backup revision numbering. Consider the following: a. Check that the entire system has backups available from all applicable parts. b. Store the backups in a safe place (e.g. in an encrypted storage), restricted by role-based access control mechanisms. c. Ensure the security of the configuration PCs that may have local copies of device configurations. d. Validate the backups to make sure that they’re working. 11. Follow cyber security best practices for installation, operation, and decommissioning as described in the product’s Cyber Security Deployment Guideline and User Manual. 12. Use continuous monitoring (e.g., intrusion detection/prevention tools) to detect anomalies in the system 13. Consider hardening the system according to the following: a. Remove any unnecessary communication links in the system. b. If possible, close unused physical ports. c. Open only the necessary TCP/UDP ports in the configuration. d. Remove all unnecessary user accounts. e. Restrict traffic by firewall. f. Allow the traffic only from/to necessary hosts' IP addresses (i.e., define both source and destination in the firewall rules, where possible). g. Define client IP address as allowed address in SCADA communication protocols, if such configuration is supported. h. Remove or deactivate all unused processes, communication ports and services, where possible. i. Use physical access controls to the system installations (e.g., to server rooms and device cabinets).

Patch and workaround

Operational remediation based on structured source evidence.

Status
?Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change.
Fix availability varies by product
Affected
Fixed
An authoritative update reference is available, but the fixed version is not recorded in the structured CVE fields. Check the linked vendor advisory for the applicable release.
Action
Use the product-specific evidence above. Patch only products with a verified fixed release, and keep every affected or under-investigation state without a matching fix in the remediation queue.
Workaround
Mitigating factors describe conditions and circumstances that make an attack that exploits the vulnerability difficult or less likely to succeed. The following mitigations are recommended. 1. Obtain a cellular private access point (APN). A dedicated private cellular access point and respective SIM card subscriptions can be requested from your cellular service provider. This service doesn’t expose the traffic between remote sites and main site to the internet but rather uses cellular operator’s private wide area network (WAN). Therefore, the ARM600 wouldn’t need open ports to the internet. 2. Avoid exposing any system component to the internet. If, however, the ARM600 is exposed to the internet, only the VPN port should be opened towards the internet (e.g., Patrol management connections can be configured to use VPN tunnel and remote administration connections can be implemented by using OpenVPN PC-client). 4. Perform firewall configuration by the "allowlisting" principle, i.e., explicitly allowing only the required ports and protocols and blocking any other traffic. 6. If the internet is used as a WAN media for carrying VPN tunnels, use Demilitarized Zone (DMZ) for terminating connections from the internet (i.e., the remote connections should terminate to the DMZ network, which would be segregated from other networks by a firewall. The ARM600 server would be located into this DMZ). 7. Change the default user credentials of ARM600 and Arctic wireless gateways into non-defaults and use complex non-guessable passwords with special characters. Do not reuse passwords within the system. 8. Use administrator (i.e., root user) privileges only when required by the task. 9. Supporting systems, such as PCs used for configuration, should be frequently updated. If possible, use dedicated site PCs for upgrading and engineering purposes. At minimum, PCs should be investigated by running a full virus scan with recently updated signature files before introducing the PC to the OT system. Any data, such as device configurations and firmware update files transferred to the Arctic system should be virus scanned prior to transferring. 10. Introduce a backup policy, which will ensure periodical backups and backup revision numbering. Consider the following: a. Check that the entire system has backups available from all applicable parts. b. Store the backups in a safe place (e.g. in an encrypted storage), restricted by role-based access control mechanisms. c. Ensure the security of the configuration PCs that may have local copies of device configurations. d. Validate the backups to make sure that they’re working. 11. Follow cyber security best practices for installation, operation, and decommissioning as described in the product’s Cyber Security Deployment Guideline and User Manual. 12. Use continuous monitoring (e.g., intrusion detection/prevention tools) to detect anomalies in the system 13. Consider hardening the system according to the following: a. Remove any unnecessary communication links in the system. b. If possible, close unused physical ports. c. Open only the necessary TCP/UDP ports in the configuration. d. Remove all unnecessary user accounts. e. Restrict traffic by firewall. f. Allow the traffic only from/to necessary hosts' IP addresses (i.e., define both source and destination in the firewall rules, where possible). g. Define client IP address as allowed address in SCADA communication protocols, if such configuration is supported. h. Remove or deactivate all unused processes, communication ports and services, where possible. i. Use physical access controls to the system installations (e.g., to server rooms and device cabinets).
