🔍 How to Verify
Check if Vulnerable:
Check router web interface or CLI for version 4.4.1.r4308. Test with known exploit payloads in controlled environment only.Check Version:
Check router admin interface or use vendor-specific CLI commandsVerify Fix Applied:
Verify version has changed from 4.4.1.r4308. Test API endpoint with safe payloads to confirm command injection is blocked.📡 Detection & Monitoring
