What they could let someone do.

What could happen

  • Database injection

    Someone could read or change what is in the site's database: customer details, orders, password records, or a new administrator account.

    How: The software builds its questions to the database out of what visitors type, so carefully written input changes the question itself.

  • Cross-site scripting

    Someone could make your pages run their own script in visitors' browsers, to steal logins, show a fake payment form or send people to a scam site.

    How: The software puts text it was sent back onto a page without making it safe first, so a script hidden in a link, form or comment runs as if it were part of your site.

  • Missing checks

    Someone could do things only an administrator should: change settings, see private data, or give themselves more rights.

    How: Part of the software forgets to check who is asking before it does what was asked.
