What they could let someone do.

What could happen

  • 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.

  • Information leak

    It could give away information that should stay private, such as user details, file locations or settings, which makes other attacks easier.

    How: The software shows, sends or logs more than it should.

  • 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.
