Summary

A vulnerability in multiple Mitsubishi Electric products communicating over CC-Link IE TSN involves improper enforcement of message integrity during transmission. An attacker with access to a CC-Link IE TSN network can tamper with communication data (control input/output values) by sending specially crafted packets under specific timing conditions. This could cause a denial-of-service (DoS) condition by interfering with the control function or causing incorrect operation.

Risk Assessment

An attacker with access to the industrial network could alter control data, leading to incorrect machine operation and production line downtime. In OT environments this may disrupt the production process, damage equipment, or endanger personnel safety.

Recommendation

Restrict access to the CC-Link IE TSN network to trusted devices and network segments only, and implement industrial network protections (segmentation, firewalls, traffic monitoring). Also monitor Mitsubishi Electric security advisories and apply available updates or mitigations.
