What they could let someone do.
What could happen
- 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.
Read about it here - Forged requests
Someone could get a signed in administrator to change something without knowing, such as adding a new admin or changing settings, just by visiting a page.
How: The software does not check that a change came from its own pages, so another site can quietly send one through the administrator's browser.
