Samsung / Dell Printer SNMP Backdoor

Critical Nessus Plugin ID 63136


The remote printer has a backdoor administrator account.


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 can
exploit this to take control of the printer.


To secure the printer, do one or more of the following :

- 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.
