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
Fuji Electric Monitouch V-SFT-6 is vulnerable to an out-of-bounds write while processing a specially crafted project file, which may allow an attacker to execute arbitrary code.

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 · moderate confidence

Fuji Electric Monitouch V-SFT-6 contains an out-of-bounds write vulnerability in its project file parsing logic. When processing a specially crafted malicious project file, the software writes data beyond allocated buffer boundaries, leading to memory corruption that can be leveraged for arbitrary code execution.

MitigationUsers should avoid opening untrusted or unverified project files until an official vendor patch is available. Organizations should also implement file import validation policies and consider network segmentation for HMI engineering workstations.

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. Verify Monitouch V-SFT-6 installation
    Check if Fuji Electric Monitouch V-SFT-6 is installed on the system. Look in Windows Add/Remove Programs, or check typical installation directories such as C:\Program Files\Fuji Electric\ or C:\Program Files (x86)\Fuji Electric\ for a folder named V-SFT-6 or similar.
    Affected if If the software is not installed, the system is not affected by this CVE.
  2. Determine installed V-SFT-6 version
    Locate the V-SFT-6 executable (commonly named V-SFT-6.exe or similar), right-click it, select Properties, and record the File Version information. Alternatively, launch the application and navigate to Help > About to view the version.
    Affected if The system is potentially affected if the installed version matches the vulnerable version range specified in the vendor advisory.
  3. Identify project file parsing usage
    Check the application for recently opened project files. Look within the software for a recent projects list, or check the user documents folder for .vsf or other Monitouch project file extensions. Windows Event Viewer may also show Application events related to V-SFT-6 file operations.
    Affected if The vulnerability is triggered only when the software parses a specially crafted project file; merely having the software installed does not automatically expose the system.
  4. Check for crash or exploitation indicators
    Review the V-SFT-6 application data directory (typically under %APPDATA%\Fuji Electric\ or %LOCALAPPDATA%\Fuji Electric\) for crash logs, error reports, or memory dump files. Also check Windows Security event logs for unexpected process behavior or code injection related to V-SFT-6.exe.
    Affected if If unexpected crashes, error logs, or suspicious activity coincide with recent project file operations, the vulnerability may have been exploited.

A system is affected if Fuji Electric Monitouch V-SFT-6 is installed with a version within the vulnerable range AND a user has opened or could open a malicious project file with the software.
