A vulnerability has been found in Mitsubishi Electric MELSEC MX Controller, Master, local module, CC-Link IE TSN interface board, Motion module, Motion Control Board, Block-type remote module, 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, Inverter FR-A800, F800, E800 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, Industrial Computer MELIPC series, GOT3000 Series, CC-Link IE TSN Communication Unit, Motion Control Software, CC-Link IE TSN Communication Software for Windows, Analysis Support Software MELSOFT VIMA, Designated communication LSI DeviceKit, Designated communication LSI, Remote Station Communication LSI with GbE-PHY, CC-Link IE TSN Master, local module Designated communication LSI SDK and Remote station software development kit and classified as critical. Affected by this vulnerability is an unknown code block. The manipulation with an unknown input leads to a message integrity vulnerability. The CWE definition for the vulnerability is CWE-924. The product establishes a communication channel with an endpoint and receives a message from that endpoint, but it does not sufficiently ensure that the message was not modified during transmission. As an impact it is known to affect integrity, and availability. The summary by CVE is:

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, 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 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, Industrial Computer MELIPC series, 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, Master/Local module Designated communication LSI, 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.

It is possible to read the advisory at mitsubishielectric.com. This vulnerability is known as CVE-2026-13584 since 06/29/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 07/30/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
