"The remote web server is affected by a remote command execution
vulnerability." );
 script_set_attribute(attribute:"description", value:
"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." );
