CVE-2025-8894
📋 TL;DR
A heap-based buffer overflow vulnerability in Autodesk products allows malicious PDF files to cause crashes, leak sensitive data, or execute arbitrary code. This affects users of specific Autodesk software versions that parse PDF files. Attackers can exploit this by tricking users into opening specially crafted PDF documents.
💻 Affected Systems
- Autodesk Access
- Other Autodesk products with PDF parsing functionality

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the current user, potentially leading to full system compromise, data theft, or ransomware deployment.
Likely Case
Application crashes and potential information disclosure through memory leaks when users open malicious PDF files.
If Mitigated
Limited impact with proper security controls like application sandboxing, least privilege, and network segmentation preventing lateral movement.
🎯 Exploit Status
Exploitation requires user interaction to open a malicious PDF file. The vulnerability is in the parsing logic, making reliable exploitation non-trivial but feasible for skilled attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions specified in Autodesk advisory ADSK-SA-2025-0018
Vendor Advisory: https://www.autodesk.com/trust/security-advisories/adsk-sa-2025-0018
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 application and system as required
🔧 Temporary Workarounds
Disable PDF file opening in Autodesk products
allConfigure Autodesk products to not automatically open or parse PDF files, reducing attack surface.
Check product-specific settings for file association controls
Use application control policies
allImplement application whitelisting to prevent execution of unauthorized code even if exploitation occurs.
Configure Windows AppLocker or equivalent macOS/Linux controls
🧯 If You Can't Patch
- Implement network segmentation to isolate Autodesk systems from critical assets
- Deploy endpoint detection and response (EDR) to monitor for exploitation attempts and memory corruption patterns
🔍 How to Verify
Check if Vulnerable:
Check installed Autodesk product versions against the affected versions listed in Autodesk advisory ADSK-SA-2025-0018Check Version:
Check via Autodesk product 'About' dialog or system information tools specific to each productVerify Fix Applied:
Verify that Autodesk products have been updated to patched versions specified in the advisory and test PDF file processing functionality📡 Detection & Monitoring
Log Indicators:
- Application crashes in Autodesk products when processing PDF files
- Unusual memory access patterns or heap corruption errors in system/application logs
Network Indicators:
- Unusual outbound connections from Autodesk processes post-PDF opening
- PDF file downloads followed by process anomalies
SIEM Query:
Example: (process_name:"autodesk*.exe" AND event_type:"crash") OR (file_extension:".pdf" AND process_name:"autodesk*")
