CVE-2022-29828Network attack vector

Information disclosure via hard-coded cryptographic key

Published Nov 24, 2022 · Updated Apr 25, 2025

Hard-coded cryptographic keys in Mitsubishi Electric GX Works3 1.000A and later allow remote attackers to disclose sensitive information. The software relies on a fixed cryptographic key to protect project and program data; Mitsubishi Electric has not disclosed the key's code location or recovery path. No authentication is required, and recovered information enables unauthorized viewing of project files and controller programs or execution of controller programs.
