Overview
On February 27 (local time), Cisco officially released a security advisory to announce a critical security vulnerability (CVE-2019-1663) in Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router, and Cisco RV215W Wireless-N VPN Router. This vulnerability exists in the web-based management interface of the preceding products, which fails to properly validate user-supplied data.
