CVE-2026-13584 Information tampering and Denial-of-service (DoS) vulnerability in CC-Link IE TSN communication protocol
Description
Improper Enforcement of Message Integrity During Transmission in a Communication Channel vulnerability in Mitsubishi Electric MELSEC MX Controller MX-R model, MELSEC MX Controller MX-F model, Master/local module, CC-Link IE TSN interface board, Motion module, MELSEC iQ-L Series Motion Module, Motion Control Board, Block-type remote module, Block-type remote module with safety functions, Analog-Digital converter module, Digital-Analog converter module, CC-Link IE TSN compatible coupler, FPGA module, Tension meter, AC Servo MELSERVO-J5, AC Servo MELSERVO-JET, Liner Track System MTR-S series Linear track control module, Inverter FR-A800/F800/E800/D800 Series, Industrial Robot CR800-D series controller Network Base Card, CC-Link IE TSN expansion unit, CC-Link IE TSN-CC-Link IE Field Network bridge module, CC-Link IE TSN-AnyWireASLINK bridge module, Energy Measuring Unit CC-Link IE TSN Communication Unit, GOT3000 Series, CC-Link IE TSN Communication Unit, Motion Control Software, CC-Link IE TSN Communication Software for Windows, Analysis Support Software MELSOFT VIMA, Master/Local module Designated communication LSI DeviceKit, Remote Station Communication LSI with GbE-PHY, CC-Link IE TSN Master/Local module Designated communication LSI SDK, and Remote station software development kit allows an attacker with access to a CC-Link IE TSN network to tamper with communication data (control input/output values) 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.
