Senserva AI Opinion for CVE-2017-6334
This flaw lets an authenticated user hit dnslookup.cgi on NETGEAR DGN2200 routers running firmware through 10.0.0.50 and run arbitrary OS commands, meaning full device takeover from the web interface. These are consumer and small-office gateways often left on default credentials, which turns the authentication requirement into a low bar. CISA confirmed active exploitation in March 2022 and EPSS puts exploit probability at 72 percent, so exposed units are being targeted.
Do this: Identify any DGN2200 devices on your network, upgrade past firmware 10.0.0.50 or retire the hardware, and remove remote management access immediately.
