Security readout for executives and security teams
Plain-English summary
This flaw affects Mitsubishi Electric engineering software used around automation projects. A built-in cryptographic key can let a remote unauthenticated attacker read or change sensitive project information. The business concern is loss or manipulation of industrial project files, not direct service outage from the CVSS data provided.
Executive priority
Treat this as urgent for industrial engineering environments using the affected Mitsubishi software. It can compromise sensitive automation project data without authentication, but available sources do not show confirmed active exploitation.
Technical view
CVE-2022-29830 is CWE-321 in GX Works3 1.000A through 1.095Z and Motion Control Setting 1.000A through 1.065T. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N, indicating remote unauthenticated confidentiality and integrity impact without availability impact.
Likely exposure
Exposure is likely limited to organizations that use the named Mitsubishi Electric GX Works3 software versions or its related Motion Control Setting software. The bundle does not identify affected operating systems, deployment patterns, or internet exposure conditions.
Exploitation context
The source bundle does not cite active exploitation, and KEV is false. Risk remains high because exploitation is described as remote, unauthenticated, low-complexity, and capable of disclosing or tampering with sensitive project files.
Researcher notes
Do not expand scope beyond the two named products and version ranges. The provided evidence supports hard-coded cryptographic key risk, remote unauthenticated access, and confidentiality/integrity impact, but not weaponized exploitation or specific fixed versions.
Mitigation direction
- Inventory GX Works3 and Motion Control Setting versions in engineering environments.
- Consult Mitsubishi Electric advisory 2022-015 for vendor-approved remediation instructions.
- Prioritize remediation where project files are sensitive or shared over reachable networks.
- Restrict access to affected engineering systems until vendor guidance is applied.
Validation and detection
- Confirm whether GX Works3 is version 1.000A through 1.095Z.
- Confirm whether Motion Control Setting is version 1.000A through 1.065T.
- Review exposure paths for remote access to affected engineering workstations or project files.
- Verify remediation status against Mitsubishi, JVN, and CISA advisory details.

Use of Hard-coded Cryptographic Key
Use of Hard-coded Cryptographic Key represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
