CVE-2022-42947
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 X_B file when parsed through Autodesk Maya 2023 and 2022 can be used to write beyond the allocated buffer. This vulnerability can lead to arbitrary 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 buffer overflow vulnerability exists in Autodesk Maya 2022 and 2023 when parsing maliciously crafted X_B files. The vulnerability occurs during file parsing where a write operation exceeds the allocated buffer boundary, potentially allowing an attacker to achieve arbitrary 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.
-
Identify Maya installation and versionOn Windows, check the version in Help > About Maya or via the installer. On Linux/Mac, run 'maya -version' in the terminal. Also check the installation directory for Maya version folders.Affected if Maya version is 2023 (any update) as listed in affected versions
-
Locate Maya installation directoriesCommon paths: Windows: C:\Program Files\Autodesk\Maya2023\ or C:\Program Files\Autodesk\Maya2023\bin\ ; Linux: /usr/autodesk/maya2023/ ; Mac: /Applications/Autodesk/Maya2023/Affected if Maya 2023 is installed in any standard location
-
Verify X_B file format support existsX_B is an older DirectX model format. Check if Maya has import capabilities for this format by looking for FBX, DXF, or X_B related plugins in the plug-in manager (Window > Settings/Preferences > Plug-in Manager).Affected if X_B import functionality is available or any X_B-related plugins are loaded in Maya
-
Check for recently opened X_B filesReview Maya recent files list (File > Recent Files), system temp directories, or file access logs for any .x_b files that may have been opened.Affected if Any X_B files have been opened or imported into Maya 2023
You are affected if Maya 2023 is installed and X_B files can be imported or have been opened, as the buffer overflow occurs during X_B file parsing.

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 X_B files in Maya until vendor patches are applied. Monitor Autodesk security advisories for official patches.
