This plug-in detects attempts to exploit a security issue affecting D-Link DSL-2740R devices, which permit remote, unauthenticated attackers to change the DNS settings from the WAN side. Exploitation is trivial, as it requires just to invoke a server-side page with the IP addresses of the primary and secondary DNS servers.
