Some basics that are self-evident:

  • Infected/harmful file can be uploaded for other users to download
  • A bug in the web-site's code allowing code execution, thus allowing execution of the uploaded file on the web-server itself
  • DoS (ofcourse, but that's also possible without uploads)

But what else?
