## Description

A vulnerability in the web-based management interface of Cisco Small Business RV042, RV042G, RV320, and RV325 Routers could allow an authenticated, Administrator-level, remote attacker to cause an unexpected reload of an affected device, resulting in a denial of service (DoS) condition. To exploit this vulnerability, an attacker would need to have valid Administrator credentials on the affected device.   This vulnerability is due to improper validation of user input that is in incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface of the affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a DoS condition.
