  - CVE-2017-16798: The is_file_acceptable function in modules/FileManager/action.upload.php only
  blocks file extensions that begin or end with a 'php' substring, which allows remote attackers to
  bypass intended access restrictions or trigger XSS via other extensions, as demonstrated by .phtml,
  .pht, .html, or .svg.

  - CVE-2017-16799: In modules/New/action.addcategory.php, stored XSS is possible via the m1_name
  parameter to admin/moduleinterface.php during addition of a category, a related issue to
  CVE-2010-3882.");
