Mitsubishi Electric CC-Link IE TSN Communication Protocol

CVSS 7.1 HIGH

Risk 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.

CVE-2026-13584

Remediations

For customers 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.
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.
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.
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.
