🔍 How to Verify
Check if Vulnerable:
Check if running Motivian CMS v41.0.0 and test file upload functionality in Content/Gallery/Images componentCheck Version:
Check CMS admin panel or configuration files for version informationVerify Fix Applied:
Test file upload with malicious extensions and verify they are blocked or sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to Content/Gallery/Images
- Files with suspicious extensions (.php, .jsp, .asp) in upload directories
- Multiple failed upload attempts
Network Indicators:
- POST requests to upload endpoints with unusual file types
- Traffic patterns suggesting webshell communication
SIEM Query:
source="web_server" AND (uri="/Content/Gallery/Images" OR uri CONTAINS "upload") AND (file_extension="php" OR file_extension="jsp" OR file_extension="asp")
