Project disclosure via hard-coded cryptographic key
Published Nov 24, 2022 · Updated Nov 7, 2025
Hard-coded cryptographic keys in four Mitsubishi Electric FA engineering applications allow remote attackers to disclose project data. The applications rely on a hard-coded cryptographic key to protect project and controller access; the vendor has not disclosed its storage or use locus. No authentication is required; successful access exposes programs and project files and can permit unauthorized program execution on connected controllers.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
