CVE-2025-54496
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 · uneditedA maliciously crafted project file may cause a heap-based buffer overflow in Fuji Electric Monitouch V-SFT-6, which may allow the 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 confidenceA heap-based buffer overflow vulnerability exists in Fuji Electric Monitouch V-SFT-6 when parsing maliciously crafted project files. The overflow occurs during file processing, allowing an attacker to corrupt heap memory and potentially execute arbitrary code with the privileges of the application.

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.
-
Identify installed Monitouch V-SFT-6 versionOpen Monitouch V-SFT-6 and navigate to Help > About, or check the program version in Windows Add/Remove Programs or the program installation directoryAffected if The installed version is 6.2.7.0 through 6.2.8.x (any version >= 6.2.7.0 and < 6.2.9.0)
-
Confirm project file parsing functionalityVerify the software can open or import project files (.sf6 or vendor project format) - this is the default operation mode of the HMI development softwareAffected if The software is used to create, edit, or open project files, which triggers the vulnerable parsing code path
-
Audit recent project file activityReview recently opened project files in the software or check the project file history to identify files that were parsedAffected if Any project files have been opened in the affected software version, especially files from external or untrusted sources
The environment is affected if Monitouch V-SFT-6 version 6.2.7.0 or higher but below 6.2.9.0 is installed and the software is used to process project files.

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 · scoped6.2.9.0
Apply vendor patches when available; until then, avoid opening untrusted project files and restrict network access to affected systems. Consider isolating HMI systems on separate network segments.
Monitouch V SFT version 6.2.9.0 or later
- Download the fixed version of Monitouch V SFT (version 6.2.9.0 or later) from the official Fuji Electric support site at felib.fujielectric.co.jp
- Verify the downloaded installer file integrity using checksums if provided by the vendor
- Close any running instances of the Monitouch V SFT software
- Run the installer and follow the vendor's standard upgrade procedure
- After upgrading, verify the new version by checking the software's About or version information
- Since the vulnerability is triggered by malicious project files, exercise caution when opening project files from untrusted sources even after patching
