  users

  - No CVE: A path traversal vulnerability where a low privileged user may download arbitrary files
  or elevate his privileges

  Crafting a download request and adding a path traversal vector to it, an authenticated user, can
  use this function to download files that are outside the normal scope of the download feature
  (including sensitive files).

  In addition, the function can be called from a low privileged user, a user that is logged on to
  the User Portal. A combinations of these two vulnerabilities can be used to compromise the
  integrity of the server, by allowing a user to elevate his privileges.");
