CVE-2021-27030

Code execution via unchecked ZIP entry paths

Published Apr 19, 2021 · Updated Aug 3, 2024

Directory traversal in Autodesk FBX Review 1.4.1.0 and 1.5.0 allows remote attackers to execute code through a malicious FBX file. The ZIP parser uses attacker-supplied entry filenames in file operations without first validating that their paths remain inside the intended directory. Exploitation requires the targeted user to visit malicious content or open the file, and resulting code runs with that user's privileges.
