Denial of service via malformed project file
Published Dec 17, 2021 · Updated Aug 3, 2024
Out-of-bounds reads in Mitsubishi Electric FA engineering software allow attackers to cause denial of service via a malicious project file. Project-file processing reads beyond an allocated buffer, but Mitsubishi Electric has not identified the parser, routine, or malformed field involved. Exploitation requires a user to open attacker-supplied project data, and the published impact is limited to denial of service.
