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
Cleartext Storage of Sensitive Information in Memory vulnerability in Mitsubishi Electric Corporation GX Works3 versions 1.015R and later, GX Works2 all versions and GX Developer versions 8.40S and later allows a remote unauthenticated attacker to disclose sensitive information. As a result, unauthenticated users could obtain information about the project file for MELSEC safety CPU modules or project file for MELSEC Q/FX/L series with security setting.

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

This vulnerability in Mitsubishi's engineering software (GX Works3, GX Works2, GX Developer) stores sensitive information such as project file passwords and security settings in cleartext in memory. An unauthenticated remote attacker can exploit this to read sensitive data from memory, potentially gaining access to MELSEC safety CPU modules and Q/FX/L series PLC project files with security settings enabled.

MitigationApply vendor patches when released. In the interim, restrict network access to engineering workstations, implement strict access controls, and monitor for unauthorized access attempts to mitigate exposure of cleartext sensitive data in memory.

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 Mitsubishi engineering software
    Check installed programs for GX Works3, GX Works2, or GX Developer on the engineering workstation
    Affected if Any of these three products are installed
  2. Determine GX Works3 version
    Open GX Works3, go to Help > Version Information, or check the program's file properties to find the exact version number
    Affected if Version is >= 1.015r and <= 1.086q, or >= 1.087r
  3. Check for GX Works2 or GX Developer installations
    Verify if GX Works2 or GX Developer is installed, as these versions are also affected regardless of specific version numbers
    Affected if Either GX Works2 or GX Developer is installed
  4. Identify if project files with security settings exist
    Locate any .gxw3, .gxw2, or .gpx project files on the workstation that were opened with security settings (passwords, security keys) enabled
    Affected if Project files with security settings have been opened in the affected software
  5. Assess network exposure of engineering workstation
    Review network access controls and firewall rules to determine if the workstation with the affected software is accessible from unauthorized network segments
    Affected if The workstation is accessible from network segments beyond the trusted engineering zone

The environment is affected if any version of GX Works3 within the specified ranges, or any version of GX Works2/GX Developer, has been used to handle project files with security settings, and the workstation is network-accessible to untrusted attackers.
