Is it possible to extract the root password from the file system?

[Dan Dubovik]

Can you SSH as the hammerhead user?

When you FTP as the hammerhead user, can you move the script.php file to the
htdocs directory?  It has 777 permissions, so should be able to open it /
drop a file there.

If you can get a PHP file uploaded and able to execute properly, perhaps a
PHP based shell could help?
