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
  • 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.
