🔍 How to Verify
Check if Vulnerable:
Check firmware version in admin panel Settings > About. If version is below 3.0, device is vulnerable.Check Version:
curl -s http://[airtame-ip]/api/v1/system/info | grep versionVerify Fix Applied:
Verify firmware version is 3.0 or higher in Settings > About. Test authentication bypass by attempting to set custom PHPSESSID cookie.📡 Detection & Monitoring
