CVE-2021-32931
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 · uneditedAn uninitialized pointer in FATEK Automation FvDesigner, Versions 1.5.88 and prior may be exploited while the application is 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 · high confidenceAn uninitialized pointer vulnerability exists in FATEK Automation FvDesigner versions 1.5.88 and prior. When the application parses specially crafted project files, the uninitialized pointer can be exploited to achieve 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 FvDesigner installationSearch for FvDesigner executable or installation directory on the system. Common locations include C:\Program Files\FATEK\FvDesigner or C:\Program Files (x86)\FATEK\FvDesigner. Check Start Menu shortcuts and Add/Remove Programs list.Affected if FvDesigner application is found installed on the system
-
Locate version informationRight-click the FvDesigner executable, select Properties, and view the Details tab for Product Version. Alternatively, check the version displayed in the application About/Help menu when launched.Affected if Version cannot be determined or shows as 1.5.88 or lower
-
Compare version against affected rangeCompare the installed version number to the affected range of <= 1.5.88. If the exact version is unknown, check if the installation date is prior to when patches for 1.5.88 became available.Affected if Installed version is 1.5.88 or any version lower than 1.5.88
-
Identify project file handlingExamine recent project files (.fdp, .fcf, or FvDesigner project extensions) opened by the application. Check application logs or recent files list if available.Affected if Project files from untrusted or unknown sources have been opened with FvDesigner
The environment is affected if FvDesigner is installed and the installed version is 1.5.88 or any prior version.

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 dataOrganizations using FvDesigner should upgrade to a version beyond 1.5.88 when available, and avoid opening project files from untrusted sources as the primary attack vector.
