Samsung / Dell Printer SNMP Backdoor

critical Nessus Network Monitor Plugin ID 6639
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote host 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 hardcoded 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

Apply an optional firmware update. Contact the device's vendor for more information. In addition one can, disable SNMPv1/v2 on the printer and instead use the secure SNMPv3 mode
