CVE-2024-12671
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 through Autodesk Navisworks, may force an Out-of-Bounds Write vulnerability. A malicious actor may leverage this vulnerability to cause a crash, cause data corruption, 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 confidenceAn out-of-bounds write vulnerability exists in Autodesk Navisworks when parsing maliciously crafted DWFX files. The vulnerability allows a malicious actor to write data beyond allocated buffer boundaries during file parsing, potentially leading to memory corruption that can be leveraged for 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 Autodesk Navisworks is installedCheck for Navisworks installation via registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{ProductCode} or inspect common install paths such as C:\Program Files\Autodesk\Navisworks Manage 2025\ or C:\Program Files\Autodesk\Navisworks Simulate 2025\Affected if Navisworks is present on the system
-
Determine installed Navisworks versionRetrieve version information from the Navisworks executable (e.g., nvwfxfvw.dll or launcher application) via file properties, or query the registry value DisplayVersion under the Navisworks uninstall keyAffected if The installed version falls within the range >= 2025 and < 2025.4
-
Identify DWFX file parsing usageInspect recent file access or look for .dwfx file associations with Navisworks in the system registry under HKCR\.dwfx\OpenWithProgidsAffected if Navisworks is configured to open or parse DWFX files and the installed version is in the affected range
A user is affected if Autodesk Navisworks version 2025.0 through 2025.3.x is installed and a malicious DWFX file is opened in that software, triggering the out-of-bounds write during parsing.
