CVE-2025-1429
📋 TL;DR
A heap-based buffer overflow vulnerability in Autodesk AutoCAD allows attackers to craft malicious MODEL files that can crash the application, leak sensitive data, or execute arbitrary code when opened. This affects AutoCAD users who open untrusted MODEL files. The vulnerability requires user interaction to open a malicious file.
💻 Affected Systems
- Autodesk AutoCAD
- Autodesk AutoCAD LT

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the AutoCAD process, potentially leading to full system compromise if AutoCAD runs with elevated privileges.
Likely Case
Application crash or denial of service, with potential for data leakage from memory.
If Mitigated
Limited impact if proper file handling controls and least privilege principles are implemented.
🎯 Exploit Status
Exploitation requires user interaction to open a malicious file. Heap manipulation adds complexity but reliable exploitation is possible.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Latest AutoCAD 2022 updates (specific version in vendor advisory)
Vendor Advisory: https://www.autodesk.com/trust/security-advisories/adsk-sa-2025-0001
Restart Required: No
Instructions:
1. Open AutoCAD. 2. Go to Help > Check for Updates. 3. Install all available updates. 4. Alternatively, download updates from Autodesk's official support site.
🔧 Temporary Workarounds
Restrict MODEL file handling
allConfigure AutoCAD to not automatically open MODEL files or restrict file associations
Implement application whitelisting
windowsUse AppLocker or similar to restrict execution of AutoCAD to trusted locations only
🧯 If You Can't Patch
- Implement strict file handling policies: Only open MODEL files from trusted sources
- Run AutoCAD with least privilege: Ensure it doesn't run with administrative rights
🔍 How to Verify
Check if Vulnerable:
Check AutoCAD version against affected versions listed in Autodesk advisory ADSK-SA-2025-0001Check Version:
In AutoCAD: Type ABOUT in command line or check Help > About AutoCADVerify Fix Applied:
Verify AutoCAD version is updated to latest release and no longer listed as vulnerable in advisory📡 Detection & Monitoring
