    Metadata details:
    filename: multi_ncc_ping_exec.rb
    path of file: ./repos/metasploit-framework/modules/exploits/linux/http
    
    the code of the file until where you have to start completion: ##

  def check
    begin
      res = send_request_cgi({
        'method' => 'GET',
        'uri'    => normalize_uri(target_uri.path)
      })

      # unknown if other devices also using mini_httpd
      if res && [500].include?(res.code) && res.headers['Server'] && res.headers['Server'] =~ /mini_httpd/
        return Exploit::CheckCode::Detected
      end
