Samsung printers contain hardcoded backdoor account, US-CERT warns

Dupple (1016592) writes "Printers manufactured by Samsung have a backdoor administrator account hard coded in their firmware that could enable attackers to change their configuration, read their network information or stored credentials and access sensitive information passed to them by users.

The hardcoded account does not require authentication and can be accessed over the Simple Network Management Protocol (SNMP) interface of the affected printers, the U.S. Computer Emergency Readiness Team (US-CERT) said in a security advisory.

SNMP is an Internet protocol commonly used to monitor and read statistics from network-attached devices.

The SNMP account found in Samsung printers has full read and write permissions and remains accessible even if SNMP is disabled using the printer's management utility, US-CERT said."
