CVE-2025-9453
📋 TL;DR
This CVE describes an Out-of-Bounds Read vulnerability in Autodesk products when parsing malicious PRT files. Attackers can exploit this to crash applications, read sensitive memory data, or potentially execute arbitrary code. Users of affected Autodesk software are at risk.
💻 Affected Systems
- Autodesk Access
- Other Autodesk products that parse PRT files
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or ransomware deployment.
Likely Case
Application crashes causing denial of service and potential data corruption, with possible information disclosure from memory reads.
If Mitigated
Application crashes with limited impact if proper network segmentation and least privilege are enforced.
🎯 Exploit Status
Exploitation requires user interaction to open a malicious file, but crafting such files may be complex.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions.
Vendor Advisory: https://www.autodesk.com/trust/security-advisories/adsk-sa-2025-0024
Restart Required: Yes
Instructions:
1. Visit the vendor advisory URL for details.
2. Update affected Autodesk products to the latest patched version via official update channels.
3. Restart systems after applying updates.
🔧 Temporary Workarounds
Block PRT file extensions
allPrevent processing of PRT files at network or endpoint level to reduce attack surface.
User awareness training
allEducate users to avoid opening PRT files from untrusted sources.
🧯 If You Can't Patch
- Implement application whitelisting to restrict execution of vulnerable software.
- Use network segmentation to isolate systems running affected software from critical assets.
🔍 How to Verify
Check if Vulnerable:
Check installed Autodesk product versions against the vendor advisory; if unpatched and PRT file parsing is enabled, assume vulnerable.Check Version:
Check within the Autodesk product's 'About' or 'Help' menu, or use system-specific commands (e.g., on Windows: check installed programs in Control Panel).Verify Fix Applied:
Confirm Autodesk products are updated to versions listed in the vendor advisory as patched.📡 Detection & Monitoring
Log Indicators:
