Cisco Systems releases patches for small business RV Series routers and firewalls to address vulnerabilities that could allow attackers to execute arbitrary commands and overwrite files on the vulnerable devices. The affected products are Cisco RV120W Wireless-N VPN Firewall, Cisco RV180 VPN Router, and Cisco RV220W Wireless Network Security Firewall. The fixes for the first three models are expected later this month, but firmware updates have been released only for those three models. Users can limit the exposure of their devices to these flaws by not allowing remote access from the Internet to their administrative interfaces.”]
