There is definitely an attack vector there. Suppose an attacker can monitor the traffic, say on an unencrypted Wi-Fi hot spot. The attacker can see a DHCP request or INFORM, and race in a fake response with an URL of their own choosing. The mark's computer automatically connects there, and download some zero-day attack.
