Samsung and Dell printers Firmware Backdoor Unauthorized Access Vulnerability
The Samsung printer firmware before 20121031
Samsung (as well as some Dell printers manufactured by Samsung) issued a security advisory and an optional firmware update for all current Samsung networked laser printers and multifunction devices to enhance Simple Network Management Protocol (SNMP) security.
Samsung and Dell printers are prone to an unauthorized-access vulnerability because they contain a backdoor administrator account.
The issue affects devices only when SNMP is enabled.
Attackers can exploit this issue to gain unauthorized access to the affected device. This may aid in further attacks.
