RouterSploit — Exploitation Framework for Embedded Devices

Introduction

RouterSploit is an open-source exploitation framework written in Python, designed specifically for security testing of embedded devices. It follows a modular architecture similar to Metasploit but focuses on routers, access points, IP cameras, and other network-connected hardware.

What RouterSploit Does

• Provides exploit modules targeting known vulnerabilities in consumer and enterprise routers
• Runs credential-testing scanners to detect default or weak login passwords on network devices
• Generates payloads for reverse shells and bind shells on embedded Linux targets
• Includes generic exploit modules for common vulnerability classes like command injection and buffer overflows
• Supports a Metasploit-style interactive console for intuitive module selection and parameter configuration

Architecture Overview

RouterSploit is built as a Python package with a plugin-based module system. The core engine loads exploit, scanner, credential, and payload modules from a directory tree. Each module is a Python class inheriting from a base exploit class, exposing standardised run and check methods. The interactive console (rsf) wraps readline for tab completion and session management.

Self-Hosting & Configuration

• Install via pip: pip install routersploit or clone the GitHub repository
• Requires Python 3.6+ with dependencies like requests and paramiko
• No server component needed; runs entirely from the command line
• Module database updates ship with new releases or can be added manually
• Extend by dropping custom Python exploit modules into the modules directory

Key Features

• Purpose-built for embedded and IoT device security testing
• Modular design lets researchers add new exploits without modifying core code
• Credential scanner tests default passwords across dozens of device vendors
• Scanner modules detect remotely exploitable services on target networks
• Lightweight and portable, runs on any system with Python installed

Comparison with Similar Tools

• Metasploit — general-purpose exploitation framework; RouterSploit focuses on embedded targets
• Nmap — network scanner for discovery; RouterSploit goes further with active exploitation
• Shodan — passive search engine for internet-connected devices; RouterSploit performs active testing
• Medusa / Hydra — brute-force login tools; RouterSploit bundles credential testing with exploits

FAQ

Q: Is RouterSploit legal to use? A: It is designed for authorised security testing. Use it only on networks and devices you own or have explicit permission to test.

Q: Does it support custom exploits? A: Yes. Create a Python module following the base exploit class interface and place it in the modules directory.

Q: Which device vendors are covered? A: Modules exist for D-Link, Netgear, TP-Link, Cisco, Huawei, ZTE, and many others.

Q: How is it different from Metasploit? A: RouterSploit is Python-based, lightweight, and specifically targets embedded device firmware vulnerabilities rather than general-purpose OS exploits.
