Loading vulnerability…
A buffer overflow vulnerability exists in Broadcom-based cable modems used by multiple vendors, including Sagemcom, NETGEAR, Technicolor, and COMPAL. The vulnerability can be exploited remotely by an attacker who is able to execute JavaScript in a victim's browser, leading to arbitrary code execution at the kernel level on the modem. Affected firmware versions include Sagemcom F@st 3890 (prior to 50.10.21_T4 and 05.76.6.3f), Sagemcom F@st 3686 (3.428.0, 4.83.0), NETGEAR CG3700EMR (2.01.05, 2.01.03), NETGEAR C6250EMR (2.01.05, 2.01.03), Technicolor TC7230 STEB (01.25), COMPAL 7284E (5.510.5.11), and COMPAL 7486E (5.510.5.11).

This repository contains a single Metasploit auxiliary module (modules/auxiliary/dos/http/cable_haunt_websocket_dos.rb) that targets the 'Cablehaunt' vulnerability (CVE-2019-19494) in cable modem spectrum analyzer WebSocket interfaces. The module is designed to test for the presence of a buffer overflow vulnerability by sending a large, randomized payload via a WebSocket JSON-RPC request, specifically targeting the 'fStartHz' parameter. If the target is vulnerable, this causes a denial of service, rendering the modem unreachable. The module requires the target's IP address (default 192.168.100.1), port (default 8080), and valid credentials (default admin:password). The exploit is a proof-of-concept (POC) and does not provide remote code execution or persistent access, but rather demonstrates the vulnerability by crashing the device. The code is written in Ruby and leverages Metasploit's auxiliary and HTTP client modules, as well as the 'faye-websocket' gem for WebSocket communication.
