Because parameters sent via this are not restricted by the modem, it accepts JavaScript running in the browser – which gives attackers a way in as long as they can reach the browser (although not in Firefox, apparently). If the connection is established, the spectrum analyzer can be reached indirectly from outside the local network and is, at least partly, vulnerable. According to Lyrebirds, this analyser has several problems starting with the basic problem that the WebSocket interface used to control the tool from a web browser is unsecured. Using HTTPS instead of an exposed WebSockets would have dodged that bullet by implementing Cross-Origin Resource Sharing (CORS) security. Specifically, the flaw is in a normally hidden software layer called the spectrum analyser (SA) used by Internet Service Providers (ISPs) to troubleshoot a subscriber’s connection quality.

Cable Haunt is a vulnerability that can be found in Broadcom based cable modems— hundreds of millions of which are in use today around the world. All other traffic flows normally in and out of my modem but my endpoints cannot reach the modem on its internal address space. If the first step is that the exploit executes in the browser of an endpoint on your LAN then wouldn’t a simple F/W rule: Deny Source: any/any, Destination any/LAN address of your cable modem simply prevent the compromised endpoint from sending the buffer overflow back to the cable modem? The Cable Haunt vulnerability is focused on the spectrum analyzer, a standard component of Broadcom silicon that protects modems from signal surges and other disturbances piped in by the coax.
