The webserver is configured to redirect all HTTP request traffic to HTTPS. And there seems to be different application running on 80 and 443. 

443 is not vulnerable but there are lot of vulnerability exists on 80. 
When I am trying to browse <http://example.com> through browser it redirects me to <https://example.com>. 

Now when I use nikto to scan the site at port 80 it list a lot of vulnerable links. Please suggest.
