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 D300win prior to version 3.7.1.17 is vulnerable to a write-what-where condition, which could allow an attacker to overwrite program memory to manipulate the flow of information.

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 · high confidence

Fuji Electric D300win prior to version 3.7.1.17 contains a write-what-where vulnerability that allows an attacker to write arbitrary data to arbitrary memory locations, enabling manipulation of program memory and execution flow.

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. Identify if D300win is installed
    Locate the D300win software installation on the system using standard software inventory or program directory inspection
    Affected if D300win is found installed on the system
  2. Determine the installed version of D300win
    Access version information through the software itself, its executable properties, or installation metadata
    Affected if The exact installed version number cannot be determined or is below 3.7.1.17
  3. Compare version against the vulnerable range
    Review the installed version against the affected range of versions prior to 3.7.1.17
    Affected if The installed version is lower than 3.7.1.17 (e.g., 3.7.1.16, 3.6.x, or any prior version)
  4. Verify the vulnerability context
    Confirm the vulnerability is exploitable when the affected D300win software is running and processing project files or program data
    Affected if The software is actively used with project files that could trigger the memory write condition

A system is affected if Fuji Electric D300win is installed with any version prior to 3.7.1.17.

Interim mitigation

Upgrade D300win to version 3.7.1.17 or later to remediate this vulnerability.

Recommended fix High confidence

3.7.1.17 or later

  1. Identify the current version of D300win installed in the environment
  2. Obtain Fuji Electric D300win version 3.7.1.17 or later from the official vendor
  3. Follow vendor documentation for upgrading D300win to the new version
  4. Verify the upgrade was successful by confirming the installed version is 3.7.1.17 or later
  5. Test that the D300win application functions normally after the upgrade
Caveat Review vendor release notes for any functional changes between current and new version
