CVE-2022-33884

Code execution via X_B parser over-read

Published Oct 3, 2022 · Updated Aug 3, 2024

Out-of-bounds read in Autodesk AutoCAD 2020 through 2023 allows remote attackers to execute code by supplying a crafted X_B file. The X_B parser reads past the end of an allocated buffer when it processes attacker-controlled file data. Exploitation requires the target to visit a malicious page or open the file, and code runs in the context of the current process.
