Using Nikto to scan a website for vulnerabilities

Apr 09, 2016 in laravel, security, nikto, speak-like-a-brazilian | blog

Nikto is a web server scanner, written in Perl and licensed under GNU GPL. The source code is available at GitHub.

We released a new version of Speak Like A Brazilian last week, upgrading from Laravel 4.x to 5.x. Once we had a release candidate (RC) tag ready we deployed it and ran Nikto to check for issues in the server.

The default settings are enough for an initial test, but you can take a look at nikto —help for other interesting parameters.

nikto -host https://speaklikeabrazilian.com

Here are the results of the scanning.

- Nikto v2.1.4

---------------------------------------------------------------------------
+ 1 host(s) tested

There list had a few false positives, but two outstanding issues could be easily fixed. First the .htaccess file.

# File: speaklikeabrazilian.vhost.conf
# From: https://www.nginx.com/resources/wiki/start/topics/recipes/dokuwiki/
# Block access to .htaccess files
location ~ /\.ht {
    deny  all;
}

And the second one is to hide the PHP server signature.

# File: php.ini
# From: http://www.techbrown.com/hide-server-signature-of-nginx-php-version-on-linux.shtml
expose_php = Off

It is not polite to run Nikto (or most other scanners to be honest) on web sites that you do not maintain. Some sites are behind firewalls and IDS (Intrustion Detection System) systems that may block Nikto. When that happens, you can liaise with your Ops team and schedule an internal run on an application you develop or maintain.

Nikto may help you finding flaws in your server and deployment. The next step now for Speak Like A Brazilian now is running the new code through OWASP’s ZAP Proxy, which can analyse the HTTP requests for possible bugs.

Happy hacking!
