Proof of Concept

1.            Using the default username and password (admin/admin), it is
possible to obtain all credentials used for SMB file transfer. To obtain the
file access http://<printer url>/smb_serverList.csv.

2.            The UserName and UserPassword fields are unencrypted and
visible using any text editor.
