Plugin commentThis plugin is not as accurate as like the Nessus plugin because we do not exploit the potential flaw here. It is strange because the SecurityFocus BID could not be found but this one is saved in the Nessus plugin too.

Bug descriptionThe Serv-U FTP server is a well-known ftp server for Windows operating systems. It is possible to crash the server by sending more than 5'000 zeros to the target. This vulnerability allows an attacker to prevent you from sharing data through FTP and may even crash this host.
Bug solutionIf the ftp server is not used it should be de-installed or de-activated. Install the newest patch or bugfix to solve the problem or upgrade to the latest software version which is not vulnerable anymore. Additionally limit unwanted connections and communications with firewalling.
