CVE-2026-13584 Vulnerability Summary

CVE-2026-13584: 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.

Assessing the Risk of CVE-2026-13584

Access Complexity Graph

The exploitability of CVE-2026-13584 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-13584

No exploitability data is available for CVE-2026-13584.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
