Go for it!

     “Giulianisecurity.com, the website for the ex-mayor’s eponymous
     infosec consultancy firm, is powered by a roughly five-year-old
     build of Joomla! that is packed with vulnerabilities. Some of those
     bugs can be potentially exploited by miscreants using basic SQL
     injection techniques to compromise the server.
     This seemingly insecure system also has a surprising number of
     network ports open – from MySQL and anonymous LDAP to a very
     out-of-date OpenSSH 4.7 that was released in 2007.”
