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].

The Rambus SafeZone Basic Crypto Module before 10.4.0, as used in certain Fujifilm (formerly Fuji Xerox) devices before 2022-03-01, Canon imagePROGRAF and imageRUNNER devices through 2022-03-14, and potentially many other devices, generates RSA keys that can be broken with Fermat's factorization method. This allows efficient calculation of private RSA keys from the public key of a TLS certificate.
