My modem and router are on separate internal address ranges, they’re not combined into a single device – The rule works as expected. A security vulnerability named “Cable Haunt,” in Broadcom’s cable modem, exposed around 200 million home broadband gateways in Europe, to remote hijacking attacks. All other traffic flows normally in and out of my modem but my endpoints cannot reach the modem on its internal address space. So any potentially comprised endpoint on my LAN’s subnet can’t reach the internal address range of my modem, so should no longer be able to deliver the buffer overflow used in the attack (that’s the question). 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? Some might have quietly done so already but expect others to take longer. Skip to main content.
