🔍 How to Verify
Check if Vulnerable:
Attempt to upload a PHP file via /admin/index.php interface. If successful without validation, system is vulnerable.Check Version:
Check CMS version in admin panel or read version file if available.Verify Fix Applied:
Test file upload with malicious extensions - should be rejected. Verify uploaded files cannot be executed.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to /admin/index.php
- PHP file uploads with suspicious names
- Multiple failed upload attempts
Network Indicators:
- POST requests to /admin/index.php with file upload content
- Unusual outbound connections from web server after upload
SIEM Query:
source="web_logs" AND (uri="/admin/index.php" AND method="POST" AND (file_extension="php" OR file_extension="phtml"))
