CVE-2020-7081
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 type confusion vulnerability in the Autodesk FBX-SDK versions 2019.0 and earlier may lead to arbitary code read/write on the system running it.
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 type confusion vulnerability exists in Autodesk FBX-SDK versions 2019.0 and earlier. Type confusion vulnerabilities occur when the software fails to verify the type of an object before using it, potentially allowing an attacker to manipulate memory and achieve arbitrary code execution with read/write capabilities on the affected 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.
-
Identify if Autodesk FBX-SDK is installedSearch for FBX-SDK libraries and headers on the system. Common locations include: /usr/local/fbx, /opt/fbx, or within application directories. On Windows, check Program Files folders. Look for files named libfbxsdk, fbxsdk.dll, or FBX SDK headers.Affected if FBX-SDK libraries or development headers are present on the system
-
Determine the installed FBX-SDK versionCheck the version string in the FBX-SDK library file metadata, header files (often contains version in filename or internal version define), or documentation/README files that shipped with the SDK. Compare the version number to the 2019.0 release.Affected if The identified version is 2019.0 or earlier, or the version cannot be determined and FBX-SDK is present
-
Identify applications or processes using FBX-SDKSearch for applications that import or link against fbxsdk libraries. Review application dependencies or search for FBX file processing code in custom applications.Affected if Any application or service on the system links to or uses the FBX-SDK library
-
Determine if the system processes untrusted FBX filesReview logs, file access patterns, or application configurations to identify if FBX files from external or untrusted sources are processed. Check if there are any services or applications configured to import or convert FBX files.Affected if The system has functionality to load, parse, or convert FBX files, especially from external or untrusted sources
The environment is affected if Autodesk FBX-SDK version 2019.0 or earlier is installed AND the system has the capability to process FBX files using that SDK.

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 dataUpdate to a version of Autodesk FBX-SDK newer than 2019.0 once available from Autodesk. As a defensive measure, avoid processing untrusted or unknown FBX files until the update is applied.
