An Access Control vulnerability exists in ATutor 2.2.4 in password_reminder.php when the g, id, h, form_password_hidden, and form_change HTTP POST parameters are set.
AChecker 1.5 allows remote attackers to read the contents of arbitrary files via the download.php path parameter by using Unauthenticated Path Traversal. This occurs through readfile in PHP. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
