Original Article Summary

View CSAF Summary Successful exploitation of this vulnerability could allow an attacker with access to the same network segment to tamper with communication data in the affected product by sending specially crafted packets under specific timing conditions. This could allow the attacker to cause a denial-of-service (DoS) condition in the affected product by interfering with its control function or causing it to operate incorrectly.

using the affected products, please refer to Mitsubishi Electric's security advisory, "https://www.mitsubishielectric.com/psirt/vulnerability/pdf/2026-005_en.pdf" and take the measures described there. https://www.mitsubishielectric.com/psirt/vulnerability/pdf/2026-005_en.pdf Mitigation For customers of the affected products, Mitsubishi Electric recommends restricting physical access to the affected products and the CC-Link IE TSN network to which the affected products are connected by taking measures such as the following: (a) managing access to and from the site where the affected products are installed, (b) locking the control panel in which the affected products and/or the network devices are installed, and (c) locking the Ethernet ports such as with port lock accessories, to minimize the risk of exploitation of this vulnerability. Mitigation For customers of the affected products, Mitsubishi Electric recommends using the affected products within a trusted network where communication with untrusted networks and hosts is blocked by a firewall or similar measures, to minimize the risk of exploitation of this vulnerability. Mitigation For customers of the affected products, Mitsubishi Electric recommends appropriately configuring credentials and access privileges for network devices installed at the boundary between trusted networks and external networks, to minimize the risk of exploitation of this vulnerability.

Recommended Practices CISA recommends users take defensive measures to minimize the exploitation risk of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolate 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 recent version available. Also recognize VPN is only as secure as its 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. 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.
