Autodesk FBX SDK is vulnerable to a stack-based buffer overflow that could allow an attacker to gain control over the affected system through a malicious file.

The vulnerability exists in the fbxsdk::FbxIO::BinaryReadSectionHeader function, where insufficient bounds checking leads to a stack-based buffer overflow (CWE-121). An attacker requires user interaction, such as convincing a user to open a crafted FBX file, to trigger the flaw.

A successful exploit could allow for arbitrary code execution, leading to full system compromise or data exfiltration. While the CVSS score of 7.8 notes the requirement for user interaction, the potential for total system impact makes this a critical risk for design and engineering workflows.

Immediate Action: Update to Autodesk FBX SDK version 2020.3.10 or later as advised by the vendor.

Proactive Monitoring: Implement endpoint protection to scan incoming FBX files for malicious content and monitor for abnormal application behavior when processing 3D data.

Compensating Controls: Restrict the opening of FBX files from untrusted or external sources to mitigate the risk of triggering the overflow.

Public Exploit Available: Unknown

Users and developers utilizing the Autodesk FBX SDK must ensure they update to the remediated version immediately. Avoid processing FBX files from untrusted sources until the update has been fully deployed across all workstations and servers.
