CVE-2021-40157

Code execution via unvalidated DAE pointer dereference

Published Sep 15, 2021 · Updated Aug 4, 2024

Untrusted pointer dereference in Autodesk FBX Review 1.5.0 and earlier allows attackers to execute code via a malicious DAE file. The DAE parser dereferences a user-supplied value as a pointer without validating it first, allowing attacker-controlled data to redirect execution in the current process. Exploitation requires the target to visit a malicious page or open the file, and resulting code runs with the process user's privileges.
