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.
Read about it here - Running code
Someone could run their own code on the server and take the site over: add malware, send spam, steal data, or use it to attack others.
How: Part of the software treats something it was sent as instructions to follow, or keeps an uploaded file somewhere it can be run.
Read about it here - 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.
