FILE SYSTEM:  Writable (public download method)
The directory sites/default/files is not writable. You may need to set the correct directory at the file system settings page or change the current directory's permissions so that it is writable.


PUBLIC FILES DIRECTORY: Not fully protected
See https://www.drupal.org/SA-CORE-2013-003 for information about the recommended .htaccess file which should be added to the public:// directory to help protect against arbitrary code execution.
