CVE-2023-25001

Code execution via unchecked SKP object use

Published Jun 27, 2023 · Updated Dec 5, 2024

A use-after-free in the SKP file parser in Autodesk Navisworks 2023 and 2022 allows remote attackers to execute code via a crafted file. The parser performs operations on an SKP object without first validating that the object still exists, leaving freed memory accessible. Exploitation requires the target to open the malicious file, and successful code runs in the context of the current Navisworks process.
