Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Use of Hard-coded Cryptographic Key vulnerability in Mitsubishi Electric GX Works3 versions from 1.000A and later allows a remote unauthenticated attacker to disclose sensitive information. As a result, unauthenticated attackers may view programs and project file or execute programs illegally.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Hard-coded cryptographic key vulnerability in Mitsubishi Electric GX Works3 allows remote unauthenticated attackers to decrypt sensitive project data, view programs and project files, and potentially execute programs illegally. The key is embedded in the software itself, enabling attackers to bypass authentication and access plaintext sensitive information.

MitigationApply vendor patches when available, rotate any exposed credentials, review project files for unauthorized access, and restrict network exposure of affected systems.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed GX Works3 version
    Open GX Works3 and navigate to the About or Version information section in the software menu, or check the program's properties in Windows Task Manager or Add/Remove Programs
    Affected if The displayed version falls within >= 1.000a to <= 1.011m, >= 1.015r to <= 1.086q, or >= 1.087r (versions 1.012-1.014 are NOT affected)
  2. Verify affected version range
    Compare your installed version number against the affected ranges: 1.000a through 1.011m, 1.015r through 1.086q, and 1.087r and higher
    Affected if Your version matches any of the affected ranges listed above
  3. Locate project files
    Search for .gxw or other project file extensions associated with GX Works3 on the system, typically found in user project directories or default installation paths
    Affected if Unencrypted project files exist on the system containing sensitive automation logic or credentials
  4. Check network exposure
    Review firewall rules and network configuration to determine if the GX Works3 software or associated ports/services are accessible from untrusted networks
    Affected if The system running GX Works3 or its project files is directly exposed to the internet or untrusted LAN segments

You are affected if GX Works3 is installed with a version matching the affected ranges AND sensitive project files exist on the system or are accessible over the network.
