CVE-2022-25796
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 Double Free vulnerability allows remote malicious actors to execute arbitrary code on DWF file in Autodesk Navisworks 2022 within affected installations. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
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 double-free vulnerability in Autodesk Navisworks 2022 when parsing malicious DWF files allows remote attackers to execute arbitrary code on affected systems. The vulnerability requires user interaction—specifically opening a crafted malicious DWF file—to trigger the double-free condition.

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 2022 is installedCheck for Navisworks 2022 in the Windows installed programs list (Control Panel > Programs and Features) or look for the application in the default install location typically at C:\Program Files\Autodesk\Navisworks Manage 2022\ or C:\Program Files (x86)\Autodesk\Navisworks Manage 2022\Affected if Autodesk Navisworks 2022 is present on the system
-
Determine the installed version numberOpen Navisworks and go to Help > About, or right-click the executable (NwView.exe, Nu舞.exe, or similar) in the install folder and view Properties > Details to find the File Version. Compare this version against the affected range (2022.0.0 through 2022.1.x)Affected if Installed version is 2022.0.0 through 2022.1.x (anything less than 2022.2)
-
Check for DWF file handling capabilityVerify the DWF importer module exists in the Navisworks installation folder - look for DWF-related DLLs such as DwfReader.dll or similar DWF parsing components in the bin folderAffected if DWF parsing modules are present and loaded by Navisworks
-
Review recent DWF file accessCheck Windows Event Viewer for recent DWF file opens, or search the user's recent documents and the Navisworks project history for DWF files opened from untrusted sourcesAffected if DWF files from untrusted sources have been opened recently using Navisworks 2022
System is affected if Autodesk Navisworks 2022 version 2022.0.0 through 2022.1.x is installed and the DWF file parsing feature is present and has been used to open files.
