A vulnerability in the web-based management interface of Cisco Small Business RV160 and RV260 Series VPN Routers could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected device. This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary commands using root-level privileges on the affected device. To exploit this vulnerability, the attacker must have valid Administrator-level credentials on the affected device.
