CVE-2020-14523Network attack vector

Code execution via project-file path traversal

Published Feb 11, 2022 · Updated Apr 16, 2025

Path traversal in Mitsubishi Electric FA products allows remote attackers to execute code through a crafted project or configuration file. When a product operates the crafted data, traversal paths can replace arbitrary executable or library files with attacker-chosen code. User interaction is required, and code execution follows when the affected software runs with administrator privileges.
