Code execution via unchecked MODEL file length
Published Mar 13, 2025 · Updated Feb 26, 2026
Heap-based buffer overflow in Autodesk AutoCAD 2022 through 2025 allows remote attackers to execute code via a crafted MODEL file. The MODEL parser copies user-supplied data into a fixed-length heap buffer without first validating its length. Exploitation requires a user to open the file or visit a malicious page and runs code in the current process; parsing can also crash the process or expose sensitive data.

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=2022 <2022.1.6
- Affected versionversion=2023 <2023.1.7
- Affected versionversion=2024 <2024.1.7
- Affected versionversion=2025 <2025.1.2
