The specific pathname ../configuration.php should be base64 encoded for a valid attack. NOTE: the vendor disputes this issue because only files under the media-manager path can be downloaded and the documentation indicates that sensitive information does not belong there. Nonetheless 2.8.1 has additional blocking of .php downloads.
