CVE-2026-16436 · Severity: info · Published 2026-10-15

Mitsubishi Electric GENESIS and related industrial automation software use a fixed, common password recovery mechanism to unlock system access. An attacker who obtains the challenge response can unlock the system remotely, gaining the ability to steal, modify, or delete critical operational data, or disrupt the system entirely. This affects multiple versions of GENESIS, GENESIS64, ICONICS Suite, and other related products used in industrial environments.

## Technical details

The vulnerability exists in the password recovery mechanism across multiple Mitsubishi Electric industrial automation products; the challenge-response used to unlock the system is identical for all users and hardcoded. An attacker with network access and knowledge of the fixed challenge response can bypass authentication without credentials. The weakness allows unauthorized access to the affected HMI/SCADA software, leading to potential data disclosure, tampering, deletion, or denial of service.
