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
  • 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.

    Read about it here
  • 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.
