CVE-2024-7670
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 w3dtk.dll through Autodesk Navisworks, can force an Out-of-Bounds Read. A malicious actor can leverage this vulnerability to cause a crash, read sensitive data, 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 · high confidenceA maliciously crafted DWFX file parsed through w3dtk.dll in Autodesk Navisworks triggers an out-of-bounds read vulnerability, allowing an attacker to cause denial of service, read sensitive memory contents, or potentially achieve arbitrary code execution in the context of the current process.

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 Navisworks installationCheck for Navisworks installation by searching for 'Autodesk Navisworks' in installed programs or looking for Navisworks executable (navisworks.exe) in typical installation paths such as C:\Program Files\Autodesk\Navisworks Manage 2025\ or C:\Program Files\Autodesk\Navisworks Simulate 2025\Affected if Navisworks 2025 series is installed on the system
-
Identify installed Navisworks versionOpen Navisworks and go to Help > About Navisworks, or right-click the navisworks.exe file, select Properties, and check the File Version field. Alternatively, check the Windows Registry under HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\Navisworks for the InstallVersion valueAffected if Version displayed is 2025, 2025.1, or 2025.2 (exactly matching these versions)
-
Confirm vulnerable component existsLocate the file w3dtk.dll in the Navisworks installation directory, typically found in C:\Program Files\Autodesk\Navisworks Manage 2025\ or C:\Program Files\Autodesk\Navisworks Simulate 2025\Affected if w3dtk.dll exists in the Navisworks 2025 installation folder
-
Check DWFX file handling capabilityVerify that Navisworks can open DWFX files by checking file associations (look for .dwfx extension handler) or attempt to open a DWFX file through Navisworks. Also check for presence of dwfx reader modules in the installation directoryAffected if DWFX file support is available or .dwfx files can be opened in Navisworks
You are affected if Navisworks version 2025, 2025.1, or 2025.2 is installed with w3dtk.dll present and DWFX file handling capability exists, as opening a malicious DWFX file could trigger the out-of-bounds read in the parsing library.

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 dataAvoid opening untrusted or unverified DWFX files in Navisworks; apply vendor-supplied security patches promptly once available.
