Memory corruption via malformed STP parser input
Published Feb 22, 2024 · Updated Aug 28, 2025
Memory corruption in Autodesk AutoCAD-family Windows applications allows remote attackers to execute code through a malicious STP file. The ASMIMPORT229A.dll, ASMKERN228A.dll, ASMkern229A.dll, and ASMDATAX228A.dll parsers perform a write access violation while processing untrusted STP data. Exploitation requires a user to open or import the file, and this flaw reaches code execution only when chained with other vulnerabilities; otherwise it corrupts process memory.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=2021 <2021.1.4
- Affected versionversion=2022 <2022.1.4
- Affected versionversion=2023 <2023.1.5
