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 Alpha5 Smart Loader Versions 3.7 and prior. The device does not perform a check on the length/size of a project file before copying the entire contents of the file to a heap-based buffer.

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

Heap-based buffer overflow vulnerability in Fuji Electric Alpha5 Smart Loader versions 3.7 and prior. The application fails to validate the size/length of a project file before copying its contents into a heap-based buffer, allowing an attacker to overflow the buffer and potentially achieve arbitrary code execution.

MitigationNetwork segment the affected system and restrict access to the loader software. Contact Fuji Electric for a patched version. If no patch available, implement input validation at network boundaries and monitor for anomalous file uploads.

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 Alpha5 Smart Loader is installed
    Check system for Alpha5 Smart Loader software installation - look for program files directory or application listing
    Affected if Alpha5 Smart Loader software exists on the system
  2. Determine installed version
    Locate the executable or check program version information for Alpha5 Smart Loader
    Affected if Version is 3.7 or any prior version (3.7, 3.6, etc.)
  3. Verify project file handling feature exists
    Confirm the loader can load or process project files - check for project file (.alp, .5al, or similar extensions) import or open functionality
    Affected if Project file loading capability is present in the installed version
  4. Check for suspicious project files
    Review any recent or unusually large project files in the application data directory or upload locations
    Affected if Project files exist that could trigger the overflow condition (unchecked size before heap copy)

System is affected if Alpha5 Smart Loader version 3.7 or prior is installed and the software processes project files without validating size/length beforehand.
