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.

An attacker could exploit this vulnerability by sending a malicious HTTP request to the target device. Successful exploitation allows the attacker to execute arbitrary code as a high-privileged user on the underlying operating system of the affected device.

A vulnerable web-based management interface is accessible via a local area network (LAN) or the remote management function. Note that the remote management function is disabled on affected devices by default.
