Cisco announced recently that it will not be releasing software updates for a vulnerability with its Universal Plug-and-Play (UPnP) service in Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers.
The vulnerability allows unauthenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition.
