CVE-2025-10089

Local code execution via installer DLL hijacking

Published Nov 18, 2025 · Updated Nov 18, 2025

DLL hijacking in all versions of four Mitsubishi Electric MILCO.S application installers allows local users to execute attacker-supplied code. During installation, the installer searches an uncontrolled path and loads an attacker-supplied DLL instead of the intended library. Exploitation requires user interaction to run a tampered package; installed applications are unaffected, and vendor-direct downloads do not introduce the malicious DLL.
