Project data disclosure and tampering via hard-coded key
Published Nov 24, 2022 · Updated Nov 7, 2025
Hard-coded keys in GX Works3 1.000A through 1.095Z and Motion Control Setting 1.000A through 1.065T let remote attackers read or alter project data. The project-file security mechanism uses a hard-coded, unchangeable cryptographic key to protect sensitive project information. Network access to project files or security keys is the gate; successful exploitation discloses or tampers with those files without authentication.

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.
