Code execution via unchecked MODEL file length
Published Jun 25, 2024 · Updated Aug 26, 2025
Heap-based buffer overflow in Autodesk AutoCAD and AutoCAD-based products allows attackers to execute code through a crafted MODEL file. The atf_asm_interface.dll parser copies user-supplied MODEL data into a fixed-length heap buffer without first validating its length. A user must open the file or visit malicious content on Windows; successful exploitation executes code in the current process or crashes it.

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 <2022.1.5
- Affected versionversion=2023 <2023.1.6
- Affected versionversion=2024 <2024.1.5
- Affected versionversion=2025 <2025.1
