This may (or may not) be a vulnerability. If they allow you to shut down the port so that no one can connect unless authorized by the owner, then its probably not a vulnerability. But its still a poor choice for security engineering. Do you know if the port can be closed? _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
