Improper Enforcement of Message Integrity (CWE-924) in the CC-Link IE TSN protocol allows an attacker with access to the same network segment to send specially crafted packets that tamper with control input/output values, potentially causing denial-of-service or incorrect operation across a wide range of Mitsubishi Electric industrial products, including PLCs, motion modules, inverters, HMIs, robots, and related software and modules.
