CVE-2026-16438 · Severity: info · Published 2026-10-15

Mitsubishi Electric's industrial automation software products (GENESIS64, ICONICS Suite, and others) assign excessive DCOM permissions to administrator accounts during installation. An attacker with administrator credentials can remotely launch and operate privileged DCOM objects that normally require User Account Control elevation, leading to data theft, system manipulation, or denial of service on affected industrial systems.

## Technical details

The affected products grant unnecessary default DCOM permissions to the product's administrator account during installation. An authenticated attacker with access to the administrator account can launch and operate DCOM objects locally or remotely without UAC elevation (CWE-266). This allows disclosure, tampering, destruction or deletion of system data, or denial of service conditions.
