CVE-2022-27868

Code execution via unchecked CATPart object use

Published Jun 21, 2022 · Updated Aug 3, 2024

Use-after-free in Autodesk AutoCAD 2023 CATPart parsing allows remote attackers to execute code via content opened by the target. The CATPart parser performs operations on an object without first validating that the object still exists, leaving a freed object reachable. Exploitation requires the target to visit a malicious page or open a malicious file and runs code in the context of the current process.
