The 'cgi.rb' CGI is installed. Some versions is vulnerable to
remote denial of service.

By sending a specially crafted HTTP POST request, a malicious user can force
the remote host to consume a large amount of CPU ressources.

*** Warning : Nessus solely relied on the presence of this CGI, it did not
*** determine if you specific version is vulnerable to that problem

Solution : Verify that your version is at least 1.8.1 or later
