CVE-2025-1432

7.8 HIGH

📋 TL;DR

A use-after-free vulnerability in Autodesk AutoCAD allows attackers to execute arbitrary code by tricking users into opening malicious 3DM files. This affects AutoCAD users who open untrusted 3D model files. Successful exploitation could lead to complete system compromise.

💻 Affected Systems

Products:
  • Autodesk AutoCAD
  • Autodesk AutoCAD LT
Versions: 2022 and earlier versions (specific versions not detailed in provided references)
Operating Systems: Windows, macOS
Default Config Vulnerable: ⚠️ Yes
Notes: All AutoCAD installations that process 3DM files are vulnerable by default. The vulnerability requires user interaction to open a malicious file.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution with full privileges of the AutoCAD process, potentially leading to complete system takeover, data theft, or ransomware deployment.

🟠

Likely Case

Application crash or limited data leakage from memory, with potential for code execution in targeted attacks.

🟢

If Mitigated

No impact if patches are applied or if users avoid opening untrusted 3DM files.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires user interaction (opening malicious file). No public exploit code is known at this time.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Latest AutoCAD updates as referenced in Autodesk advisory ADSK-SA-2025-0001

Vendor Advisory: https://www.autodesk.com/trust/security-advisories/adsk-sa-2025-0001

Restart Required: No

Instructions:

1. Open AutoCAD. 2. Navigate to Help > Check for Updates. 3. Install all available updates. 4. Alternatively, download the latest version from Autodesk's official update page.

🔧 Temporary Workarounds

Disable 3DM file association

windows

Prevent AutoCAD from automatically opening 3DM files by changing file associations

Windows: Control Panel > Default Programs > Associate a file type or protocol with a program > Change .3dm to open with Notepad or another safe application

Implement application whitelisting

all

Restrict execution of AutoCAD to trusted directories only

🧯 If You Can't Patch

  • Implement strict user training to never open 3DM files from untrusted sources
  • Deploy endpoint protection that can detect and block malicious 3DM files

🔍 How to Verify

Check if Vulnerable:

Check AutoCAD version against Autodesk's security advisory. If using AutoCAD 2022 or earlier without latest updates, assume vulnerable.

Check Version:

In AutoCAD: Type 'ABOUT' command or check Help > About AutoCAD

Verify Fix Applied:

Verify AutoCAD version is updated to latest release and check that security advisory ADSK-SA-2025-0001 is marked as resolved.

📡 Detection & Monitoring

Log Indicators:

  • AutoCAD crash logs with memory access violations
  • Unexpected AutoCAD process termination events
  • Security logs showing file access to 3DM files from untrusted locations

Network Indicators:

  • Downloads of 3DM files from external sources
  • Unusual outbound connections from AutoCAD process

SIEM Query:

EventID=1000 OR EventID=1001 AND ProcessName="acad.exe" AND ExceptionCode=0xC0000005
