Cambium ePMP SNMP Enumeration

Created

Description

Cambium devices (ePMP, PMP, Force, & others) can be administered using SNMP. The device configuration contains IP addresses, keys, and passwords, amongst other information. This module uses SNMP to extract Cambium ePMP device configuration. On certain software versions, specific device configuration values can be accessed using SNMP RO string, even though only SNMP RW string should be able to access them, according to MIB documentation. The module also triggers full configuration backup, and retrieves the backup url. The configuration file can then be downloaded without authentication. The module has been tested primarily on Cambium ePMP current version (3.2.x, as of today), PMP, and Force units.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/scanner/snmp/cambium_snmp_loot
msf auxiliary(cambium_snmp_loot) > show actions
    ...actions...
msf auxiliary(cambium_snmp_loot) > set ACTION < action-name >
msf auxiliary(cambium_snmp_loot) > show options
    ...show and set options...
msf auxiliary(cambium_snmp_loot) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
