What they could let someone do.
What could happen
- Reading files
Someone could read files on the server they should never see, such as the settings file holding the database password, or delete files the site needs.
How: The software takes a file name from a request and does not check that it stays inside its own folder.
Read about it here - 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 - 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.
