This vulnerability lies in an exposed debugging interface that evaluates user-controlled OGNL expressions without proper sanitization or authentication. Exploiting it can lead to remote code execution under the context of the application server.

📝 Note: This vulnerability affects installations that expose /adminui/debug endpoint publicly or internally without proper access control.

🧪 Proof of Concept (PoC)

🔸 HTTP Payload Vector

Simple OGNL expressions demonstrate command execution via browser or curl.

📄 PoC Script

cve-2025-54253-poc.py

🧾 Sample Exploit Log

The script logs command execution output to exploit.log:

exploit.log

🛠️ Steps to Reproduce

1. Set up a vulnerable Adobe AEM instance (<= 6.5.23.0).

2. Start Flask server (if simulating locally):
   

3. Execute OGNL in browser:
   

4. Execute via curl:
   

5. Output from commands:
   
   
   

6. Flask logging view:
   

7. PoC script run:
   

8. Verbose log view:
   

🧰 Tools & Technologies Used

• Python (PoC scripting)
• Flask (simulated server)
• Kali Linux
• curl & browser
• GitHub (PoC publishing)

✅ Mitigation

• Restrict access to /adminui/debug
• Apply vendor patches as available
• Monitor for unauthorized OGNL expressions in access logs
• Use WAF or proxy filtering to block such patterns

⚠️ Disclaimer:
This PoC is for educational purposes only. Do not use it against systems you do not own or have explicit permission to test.
