CVE-2026-16437 · Severity: info · Published 2026-10-15

Mitsubishi Electric's GENESIS industrial control software and related HMI products contain a weakness in their password recovery system that allows authenticated local administrators to unlock the system by tampering with protected management files. An attacker with admin privileges on the computer can reset the password recovery challenge-response mechanism, potentially gaining unauthorized access to critical industrial control data and functions, causing data exposure, tampering, or system outages.

## Technical details

The vulnerability allows authenticated local users with administrative privileges to bypass password recovery by tampering with a management file that stores the challenge-response mechanism (CWE-640). The file is protected by Windows permissions, but administrators can read and write it directly, enabling them to unlock the system without legitimate credentials. Successful exploitation could result in disclosure, tampering, destruction, or deletion of internal information, or denial-of-service.
