CVE-2021-22683
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 · uneditedFatek FvDesigner Version 1.5.76 and prior is vulnerable to an out-of-bounds write while processing project files, allowing an attacker to craft a special project file that may permit 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 confidenceFatek FvDesigner contains an out-of-bounds write vulnerability in its project file parsing logic. An attacker can exploit this by crafting a malicious project file that triggers the vulnerability during file processing, potentially achieving arbitrary code execution on the targeted system.

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 Fatek FvDesigner installationCheck for Fatek FvDesigner in the system program files or by searching for 'FvDesigner' in the installed programs list (Windows: Control Panel > Programs and Features, or run 'Get-ItemProperty' in PowerShell for registry keys under HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall)Affected if Fatek FvDesigner is present on the system
-
Determine installed versionRight-click the FvDesigner executable, select Properties, then the Details tab to view the File Version; alternatively, check the version displayed in the application's About or Help menuAffected if The version number is 1.5.76 or lower
-
Identify project file handlingLocate any .fdp, .fcf, or other Fatek project files on the system, or check recent file access via the application's recent files listAffected if The application is used to open or process project files (this is the vulnerable function)
-
Confirm affected version rangeCompare your installed version against the affected range: version 1.5.76 and belowAffected if The installed version is 1.5.76 or any earlier version number
A user is affected if Fatek FvDesigner is installed and the installed version is 1.5.76 or lower, with the vulnerability triggered when opening a malicious project file.

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.
From vendor dataUpdate Fatek FvDesigner to a version beyond 1.5.76 when available; until then, avoid opening project files from untrusted sources and consider network segmentation to limit exposure.
