Unpatched Calix flaw lets hackers bypass NAT to expose internal devices
An unpatched vulnerability in Calix GS7 XGS residential routers permits remote, unauthenticated attackers to create port-forwarding rules that expose internal network devices to the internet. The flaw affects routers deployed by multiple U.S. broadband providers and requires no authentication to exploit.
Why it matters: Residential customers and ISPs using Calix GS7 XGS routers face immediate risk of internal device exposure through NAT bypass; practitioners should verify whether this hardware is in use and check with their broadband provider for patch timelines or mitigations.
