CVE-2025-8892
📋 TL;DR
This vulnerability allows attackers to execute arbitrary code by tricking users into opening malicious PRT files in affected Autodesk products. The memory corruption occurs during PRT file parsing, enabling code execution within the current process context. Users of vulnerable Autodesk software are at risk.
💻 Affected Systems
- Autodesk Access and other unspecified Autodesk products
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise through arbitrary code execution, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Local privilege escalation or malware installation on the affected workstation when a user opens a malicious PRT file.
If Mitigated
Limited impact with proper application sandboxing and user privilege restrictions, potentially only crashing the application.
🎯 Exploit Status
Exploitation requires user interaction to open malicious file; no public exploit code mentioned in references.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory ADSK-SA-2025-0019 for specific patched versions
Vendor Advisory: https://www.autodesk.com/trust/security-advisories/adsk-sa-2025-0019
Restart Required: Yes
Instructions:
1. Visit the Autodesk Trust Center security advisory page
2. Identify affected products and versions
3. Download and install the latest updates from Autodesk Account or Autodesk Desktop App
4. Restart the system after installation
🔧 Temporary Workarounds
Restrict PRT file handling
allConfigure system to open PRT files with non-vulnerable applications or block PRT file execution
Windows: Use Group Policy to modify file association policies
macOS/Linux: Modify default applications for .prt files
User awareness training
allEducate users to avoid opening PRT files from untrusted sources
🧯 If You Can't Patch
- Implement application whitelisting to prevent unauthorized executables
- Use endpoint detection and response (EDR) solutions to monitor for suspicious process behavior
🔍 How to Verify
Check if Vulnerable:
Check installed Autodesk product versions against the vendor advisory; review if PRT file parsing functionality is enabledCheck Version:
Windows: Check via Control Panel > Programs or Autodesk product About dialog; macOS/Linux: Check via application menu or package managerVerify Fix Applied:
Verify installed product version matches or exceeds patched version listed in vendor advisory📡 Detection & Monitoring
Log Indicators:
- Application crashes related to PRT file parsing
- Unusual process creation from Autodesk applications
- File access events for PRT files from untrusted locations
Network Indicators:
- Downloads of PRT files from external sources
- Unusual outbound connections following PRT file access
