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

The remote version of this software is vulnerable to remote
command execution due to a lack of web requests sanitization,
especially shell metacharacters.

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

A remote attacker may submit a specially crafted web request to 
execute arbitrary command on the server with root privileges.

Solution : Upgrade to Cherokee 0.2.7 or newer
Risk factor : High";
