CVE-2024-7674
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 · uneditedA maliciously crafted DWFX file, when parsed in dwfcore.dll through Autodesk Navisworks, can force a Heap-based Buffer Overflow. A malicious actor can leverage this vulnerability to cause a crash or execute arbitrary code in the context of the current process.
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 confidenceA heap-based buffer overflow vulnerability exists in dwfcore.dll when Autodesk Navisworks parses specially crafted DWFX files. The vulnerability allows an attacker to overwrite heap memory by providing a malicious DWFX file, potentially achieving arbitrary code execution or causing a process crash.

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.
-
Check if Autodesk Navisworks is installedOpen Windows Control Panel > Programs and Features, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' in PowerShell to list installed programsAffected if Autodesk Navisworks appears in the installed programs list
-
Identify the installed Navisworks versionIn Programs and Features, locate the Autodesk Navisworks entry and note the version column, or right-click the Navisworks shortcut and select Properties > Details to view the product versionAffected if The version listed is 2025, 2025.1, or 2025.2
-
Verify dwfcore.dll is presentLocate the dwfcore.dll file in the Navisworks installation directory (typically C:\Program Files\Autodesk\Navisworks Manage 2025\ or similar path). Use File Explorer or PowerShell: Get-ChildItem -Path 'C:\Program Files\Autodesk' -Recurse -Filter 'dwfcore.dll'Affected if The file dwfcore.dll exists in the Navisworks installation folder, confirming the vulnerable component is present
-
Confirm DWFX file parsing capabilityLaunch Navisworks and attempt to open a .dwfx file, or check if the DWFX importer module is loaded. The vulnerability triggers when Navisworks parses specially crafted DWFX files.Affected if Navisworks can open or process DWFX files, meaning the parsing functionality that invokes the vulnerable dwfcore.dll code path is available
A user is affected if Navisworks version 2025, 2025.1, or 2025.2 is installed with dwfcore.dll present and DWFX file processing is enabled.
