Key facts

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 execute arbitrary code as the root user. 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-supplied input in the web-based management interface. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system as the root user.
