Description
A vulnerability in the web-based management interface of Cisco RV110W Wireless-N VPN Firewall and Cisco RV215W Wireless-N VPN Router could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device. The vulnerability is due to improper validation of user-supplied input data by the web-based management interface. An attacker could exploit this vulnerability by sending crafted requests to a targeted device. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the root user.
