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.
