Privilege escalation via replaceable installation files
Published May 19, 2022 · Updated Apr 16, 2025
Improper file access control in Mitsubishi Electric FA engineering software allows remote attackers to execute code with elevated privileges. Affected installations assign improper permissions to some product files, allowing crafted files to replace code later executed by the software. Exploitation requires an administrator to run a replaced file and can disclose, alter, or destroy information or interrupt service.
