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.

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.
