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].
Null pointer dereference vulnerability exists in multiple vendors MFPs and printers which implement Debut web server 1.2 or 1.3. Processing a specially crafted request may lead an affected product to a denial-of-service (DoS) condition. As for the affected products/models/versions, see the detailed information provided by each vendor.
Driver Distributor v2.2.3.1 and earlier contains a vulnerability where passwords are stored in a recoverable format. If an attacker obtains a configuration file of Driver Distributor, the encrypted administrator's credentials may be decrypted.
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.
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.
