CVE-2016-9304 Autodesk CVE debrief

CVE-2016-9304 was publicly disclosed on 2017-01-25. The supplied NVD record describes multiple buffer overflows in Autodesk FBX-SDK versions through 2017.0, with a potential outcome of arbitrary code execution when processing malformed DFX format files. NVD rates the issue CVSS 3.0 8.8 High with network attack characteristics, no privileges required, and user interaction required, indicating a serious risk in file-import or conversion workflows that handle untrusted content.

Who should care

Administrators, developers, and security teams using Autodesk FBX-SDK in applications or services that import, read, convert, or preview third-party 3D/content files should care most. This is especially important for environments that process untrusted files from customers, partners, or the public internet.

Technical summary

The NVD entry classifies the flaw as CWE-119 and lists Autodesk FBX-SDK versions through 2017.0 as vulnerable, with 2017.1 as the first fixed release. The attack surface is malformed file content processed by SDK-based readers or converters. The supplied CVSS vector is AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, which suggests that a remote attacker can trigger memory corruption through user-assisted file handling and potentially achieve full compromise of confidentiality, integrity, and availability.

Defensive priority

High priority for any system that ingests untrusted files via Autodesk FBX-SDK. Although the supplied enrichment does not mark this as KEV, the combination of code-execution potential, broad impact, and exposed file-processing workflows makes timely patching and exposure reduction important.

Recommended defensive actions

  • Upgrade Autodesk FBX-SDK to 2017.1 or later; the supplied NVD record lists versions through 2017.0 as vulnerable.
  • Inventory applications, plug-ins, and services that embed or depend on Autodesk FBX-SDK and confirm they are using a fixed build.
  • Treat third-party or user-supplied DFX/3D content as untrusted and quarantine suspicious files before import or conversion.
  • Run file-parsing and conversion workflows in a sandboxed or low-privilege process where practical.
  • Review the linked Autodesk vendor advisory and update internal patch, detection, and asset-tracking records accordingly.

Evidence notes

This debrief is grounded in the supplied official sources: the NVD record, the CVE record, and the referenced Autodesk vendor advisory link. The NVD metadata states vulnerable versions through 2017.0, CWE-119, and CVSS v3.0 AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. The user-provided description states that malformed DFX files can trigger buffer overflows and arbitrary code execution when read or converted.
