"The remote host is running Cherokee - a fast and tiny web server.

The remote version of this software is vulnerable to directory
traversal flaw when appending a '../' sequence to the web request.

Additionally, this version fails to drop root privileges after it 
binds to listen port.

Remote attacker can then submit specially crafted web request to 
browse any file on the server with root privileges." );
