Check if Vulnerable:
Test the meetings settings interface by attempting to inject basic XSS payloads like <script>alert('test')</script>Check Version:
Check O2OA version in administration panel or via 'java -jar o2server.jar version' commandVerify Fix Applied:
After patching, test the same XSS payloads to ensure they are properly sanitized and do not execute📡 Detection & Monitoring
