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. Check Jungo WinDriver version
    Locate the WinDriver driver file (typically windrvr.sys or similar driver files in the Windows system32/drivers folder or Jungo installation directory) and check its file version property, or use 'driverquery /v' to list driver details.
    Affected if The installed WinDriver version is below 12.6.0 or the version cannot be determined (indicating an older vulnerable release).
  2. Identify installed Mitsubishi products
    Check installed programs list (via Programs and Features or registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall) for any of these: CPU Module Logging Configuration Tool, CW Configurator, Data Transfer, Data Transfer Classic, Ezsocket, FR Configurator SW3, or FR Configurator2.
    Affected if Any of the listed Mitsubishi products are installed, as they bundle the vulnerable Jungo WinDriver component in all versions.
  3. Check for Jungo WinDriver service
    Open Services console (services.msc) and look for a service named 'Windriver' or 'Jungo WinDriver', or run 'sc query windrvr' from command prompt to query the service status and version info.
    Affected if The Windriver service exists and its associated driver file version is below 12.6.0.

You are affected if Jungo WinDriver version is below 12.6.0, or if any of the listed Mitsubishi products (which bundle WinDriver) are installed on the system.

Interim mitigation

Upgrade Jungo WinDriver to version 12.6.0 or later to remediate the vulnerability.

Recommended fix High confidence

WinDriver 12.6.0 or later

  1. 1. Identify the currently installed Jungo WinDriver version by checking the product documentation or using the vendor's version check utility
  2. 2. Navigate to the official Jungo WinDriver download page or contact Jungo/your product vendor to obtain version 12.6.0 or later
  3. 3. Review the vendor's upgrade documentation and release notes for any special installation requirements
