CVE-2017-7918 describes an improper access control vulnerability in Cambium Networks ePMP devices. After a legitimate user has performed an SNMP configuration export, an attacker can remotely trigger device configuration backups via specific MIBs. The process lacks proper access control, potentially exposing sensitive configuration data and allowing unauthorized configuration changes.

This repository contains a single Metasploit auxiliary scanner module: 'epmp1000_snmp_loot.rb'. The module targets Cambium ePMP 1000 and related devices via SNMP. It exploits vulnerabilities (CVE-2017-7918, CVE-2017-7922) that allow sensitive configuration data to be extracted using SNMP, even with only the read-only community string. The module collects a wide range of information, including SNMP community strings, RADIUS server secrets, WiFi SSIDs and keys, PPPoE credentials, and more. Additionally, it can trigger a configuration backup on the device and retrieve the backup URL, allowing unauthenticated download of the full configuration file. The module is written in Ruby and is designed to be run within the Metasploit Framework. The attack vector is network-based, requiring SNMP access to the target device. The main entry point is the 'run_host' function, which performs all enumeration and backup actions. The module is operational and provides real-world exploitation capabilities for vulnerable Cambium devices.
