CVE-2021-40159: Autodesk Inventor JT File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
First published: Tue Jan 25 2022(Updated: )
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Autodesk Inventor. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of JT files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
