CVE-2020-7081Network attack vector

Code execution via type-confused FBX file parsing

Published Apr 17, 2020 · Updated Aug 4, 2024

Type confusion in Autodesk FBX SDK 2019.5 and earlier allows attackers to execute code after a user opens a malicious FBX file. The FBX file-processing path treats crafted data as an incompatible type, causing reads and writes outside the intended memory bounds. Exploitation requires user interaction and runs code with the processing application's privileges; malformed input can instead interrupt the application.
