This vulnerability is a stack-based buffer overflow in the Autodesk FBX SDK specifically in the BinaryReadSectionHeader function. When the SDK parses a specially crafted FBX file, it can overflow a stack buffer, potentially allowing an attacker to execute arbitrary code within the process using the SDK. The CVSS v3.1 score is 7.8, indicating high impact on confidentiality, integrity, and availability. The affected version explicitly identified is 2020.3.9. No known exploits in the wild have been reported, and no vendor-provided patch or remediation level is currently stated.

If exploited, this vulnerability allows an attacker to execute arbitrary code with the privileges of the process using the Autodesk FBX SDK 2020.3.9. This can lead to full compromise of the affected application and potentially the underlying system. The vulnerability impacts confidentiality, integrity, and availability of the affected system. Exploitation requires user interaction and local access.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid processing untrusted or malicious FBX files with the affected SDK version. Monitor Autodesk's security advisories for updates on patches or mitigations.
