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 checksWork through these to decide whether this CVE applies to you.
-
Verify if Fuji Electric Tellus Lite V-Simulator is installedCheck system for presence of Tellus Lite V-Simulator software. Look in standard program installation directories or use system inventory tools to list installed applications.Affected if The software is present on the system
-
Determine the installed version of Tellus Lite V-SimulatorOpen the application and navigate to Help > About, or check the installed programs list in Control Panel/System Settings for the version number.Affected if The displayed version is lower than 4.0.20.0
-
Confirm the Simulator component is availableLaunch the Tellus Lite V application and verify the V-Simulator module or feature is accessible within the interface.Affected if The Simulator component can be opened or accessed
-
Check if the application runs with elevated privilegesReview the process properties or service configuration to determine if the simulator runs with administrative or system-level privileges.Affected if The application runs with elevated privileges (increases exploit severity)
You are affected if Fuji Electric Tellus Lite V-Simulator is installed and the version is below 4.0.20.0.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped4.0.20.0
Apply vendor-supplied patches when available; if no patch exists, consider compensating controls such as network segmentation and restricting access to the simulator.
Tellus Lite V Simulator 4.0.20.0 or later
- 1. Identify the current version of Tellus Lite V Simulator installed in your environment
- 2. If the installed version is below 4.0.20.0, download Tellus Lite V Simulator version 4.0.20.0 or later from the official Fuji Electric vendor site
- 3. Before upgrading, back up any existing project files and configurations
- 4. Install the updated version following standard vendor installation procedures
- 5. Verify the installation completed successfully and confirm the running version is 4.0.20.0 or higher
- 6. Test that the application functions normally with your existing use cases
