Module Overview

Name: Cambium cnPilot r200/r201 SNMP Enumeration
Module: auxiliary/scanner/snmp/cnpilot_r_snmp_loot
Source code: modules/auxiliary/scanner/snmp/cnpilot_r_snmp_loot.rb
Disclosure date: -
Last modification time: 2020-06-11 13:09:25 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): 161
List of CVEs: CVE-2017-5262

Cambium cnPilot r200/r201 devices can be administered using SNMP. The device configuration contains IP addresses, keys, passwords, & lots of juicy information. This module exploits an access control flaw, which allows remotely extracting sensitive information such as account passwords, WiFI PSK, & SIP credentials via SNMP Read-Only (RO) community string.

Module Ranking and Traits

Module Ranking:

normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage

This module is a scanner module, and is capable of testing against multiple hosts.

msf > use auxiliary/scanner/snmp/cnpilot_r_snmp_loot
msf auxiliary(cnpilot_r_snmp_loot) > show options
    ... show and set options ...
msf auxiliary(cnpilot_r_snmp_loot) > set RHOSTS ip-range
msf auxiliary(cnpilot_r_snmp_loot) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(cnpilot_r_snmp_loot) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(cnpilot_r_snmp_loot) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(cnpilot_r_snmp_loot) > set RHOSTS file:/tmp/ip_list.txt

Required Options

RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
