Samsung / Dell Printer SNMP Backdoor

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote printer has a backdoor administrator account.

Description :

The remote host appears to be a Samsung printer, or a Dell printer
manufactured by Samsung. It has a hard-coded SNMP read-write
community string that allows access even when SNMP has been disabled
in the printer management utility. A remote, unauthenticated attacker
could exploit this to take control of the printer.

Solution :

Either :

- Limit access to the affected SNMP service using a secure
firewall / router.

- Disable SNMPv1/v2 on the printer and instead use the
secure SNMPv3 mode.

- Apply an optional firmware update. Contact the device's
vendor for more information.
