On multiple products of SEIKO EPSON and FUJIFILM Corporation, the initial administrator password is easy to guess from the information available via SNMP. If the administrator password is not changed from the initial one, a remote attacker with SNMP access can log in to the product with the administrator privilege.
The product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker.
