Directory traversal vulnerability in MyBB (aka MyBulletinBoard) 1.4.10, and possibly earlier versions, when changing the user avatar from the gallery, allows remote authenticated users to determine the existence of files via directory traversal sequences in the avatar and possibly the gallery parameters, related to (1) admin/modules/user/users.php and (2) usercp.php.
