Multiple MFPs (multifunction printers) provided by FUJIFILM Business Innovation Corp. and Xerox Corporation provide a facility to export the contents of their Address Book with encrypted form, but the encryption strength is insufficient. With the knowledge of the encryption process and the encryption key, the information such as the server credentials may be obtained from the exported Address Book data. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

A risky-algorithm issue was discovered on Fujifilm DocuCentre-VI C4471 1.8 devices. An attacker that obtained access to the administrative web interface of a printer (e.g., by using the default credentials) can download the address book file, which contains the list of users (domain users, FTP users, etc.) stored on the printer, together with their encrypted passwords. The passwords are protected by a weak cipher, such as ROT13, which requires minimal effort to instantly retrieve the original password, giving the attacker a list of valid domain or FTP usernames and passwords.
