Vulnerable to external requests creating UDP amplification

[Phenomite]

Requests from external internet sources can trigger large amplification factors using simple payloads such as ":" or "tds:GetServices/", causing almost 100x in amplification.

Please address this in future, some recommendations.

• Add a rate limit
• Limit "Fault" messages to a smaller size
• Disable external internet access by default and when this is intended as an internal network discovery protocol
• Switch to TCP

Thanks.

Hi Phenomite,

This project was just an experimentation, I did not work on it since years.
Feel free to submit improvement using pull request.

Best Regards,
