CVE-2023-27910
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 user may be tricked into opening a malicious FBX file that may exploit a stack buffer overflow vulnerability in Autodesk® FBX® SDK 2020 or prior which may lead to code execution.
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 stack buffer overflow vulnerability exists in the FBX file parsing functionality of Autodesk FBX SDK versions 2020 and prior. When parsing a maliciously crafted FBX file, the SDK fails to properly validate input sizes before copying data into a fixed-size stack buffer, leading to overflow and potential code execution.

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.
-
Locate FBX SDK installationSearch for files named 'libfbxsdk.so' (Linux), 'fbxsdk.dll' (Windows), or check common installation directories such as /usr/local/fbx, C:\Program Files\Autodesk\FBX, or application-bundled locationsAffected if FBX SDK is present on the system
-
Identify FBX SDK versionRun 'strings' on the fbxsdk library or check file properties/VERSION_INFO resource for version strings in the format '2020.x.x'Affected if Version string is present and falls within range 2020.0 to 2020.3.3 inclusive
-
Verify application uses FBX parsingInspect application logs, dependencies, or runtime to confirm FBX file import/load functionality is in useAffected if Applications load or parse FBX files using the Autodesk FBX SDK
-
Check for vulnerable code pathsReview application code or dynamic library calls for fbx import functions (such as FbxImporter::Create, FbxIO::Open, or equivalent) that process untrusted FBX inputAffected if Application parses FBX files from potentially untrusted sources using affected SDK version
System is affected if Autodesk FBX SDK version 2020.0 through 2020.3.3 is installed and FBX file parsing functionality is used to process external FBX files.

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.
dbcve · scoped2020.3.4
Upgrade to FBX SDK version 2020.0.1 or later. Until patched, exercise caution when opening FBX files from untrusted sources.
FBX SDK 2020.3.4 or later
- Identify the current version of the FBX SDK used in your application (e.g., check the SDK header or library file version).
- Navigate to Autodesk's official FBX SDK download page (e.g., the Autodesk support or developer website).
- Download the fixed FBX SDK version 2020.3.4 or a later stable release.
- Replace the existing FBX SDK binaries (DLLs, LIBs, and header files) in your project with the newly downloaded ones.
- Rebuild your project to link against the updated SDK.
- Test your application to ensure that FBX file loading works correctly and the vulnerability is mitigated.
