Vulnerable Cisco routers

A recent The Register article describes some security flaws in the Cisco RV320 WAN routers.

Recently I've been asked, by customers, about running devices in their network that are now end of life and no longer supported by the vendor. Although these RV320 routers are not obsolete and security patches are therefore available, this is the sort of vulnerability that could cause a major problem if security patches are not available. I would therefore recommend that only vendor supportable infrastructure is deployed in a network, even if the devices only appear to be basic devices, such as a switch.
