CVE-2024-5271
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 · uneditedFuji Electric Monitouch V-SFT is vulnerable to an out-of-bounds write because of a type confusion, which could result in arbitrary code execution.
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 confidenceFuji Electric Monitouch V-SFT contains a type confusion vulnerability that leads to an out-of-bounds write condition. This memory corruption can be exploited to achieve arbitrary code execution on the affected system.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 Monitouch V-SFT installation existsSearch for Monitouch V-SFT in installed programs (Windows: Check Add/Remove Programs, Program Files; Linux: Check /opt or application directories). Look for executable files named V-SFT, sft, or related HMI development/runtime files.Affected if Monitouch V-SFT software is present on the system
-
Determine installed version numberRight-click on the main V-SFT executable (commonly named V-SFT.exe or similar in the installation directory), select Properties, then view the Details tab for version information. Alternatively, check the version listed in Add/Remove Programs.Affected if Version is displayed as a number below 6.2.3.0
-
Compare version against vulnerability rangeTake the identified version number and compare it to the affected range: any version less than 6.2.3.0 is vulnerable. Note that version 6.2.3.0 itself and higher are not affected.Affected if Installed version is less than 6.2.3.0
-
Verify if HMI runtime is exposed on networkCheck if the V-SFT runtime service or HMI interface is listening on network ports. Use 'netstat -an' or similar tools to identify listening ports associated with the software. For HMI applications, common ports may be in use.Affected if HMI runtime/service is accessible over network and version is vulnerable
System is affected if Monitouch V-SFT is installed with any version lower than 6.2.3.0, particularly if the HMI runtime is network-accessible.

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 · scoped6.2.3.0
Apply vendor patch when available; if no patch exists, implement network segmentation to minimize exposure and monitor for indicators of compromise. Consider compensating controls such as restricting access to HMI interfaces.
6.2.3.0
- Contact Fuji Electric to obtain the Monitouch V-SFT version 6.2.3.0 or later from their official support channels
- Review all system backups before performing the upgrade
- Follow Fuji Electric's official upgrade procedure for Monitouch V-SFT software
- After upgrading, verify the version number matches 6.2.3.0 or later
- Test critical operations to ensure normal functionality post-upgrade
