These address book entries are used for scanning to SMB, FTP, or IPX shares. In addition, passwords for password protected fax entries will be revealed.

However, this is a limited security measure for if there are users that have access to that portion of the web interface but shouldn't have access to the usernames and passwords stored in the device, this will not protect against such. Also, if the system manager ID and password is compromised it will make accessible the user names and password pairs stored on the device.

Also, machines running the Fiery software have the same exploit as the Fiery software works in conjunction with the Remote UI software. As the Remote UI software is the same across many machines, it is likely that the problem exists in all devices running Remote UI.
