Description

A vulnerability in the web-based management interface of Cisco Small Business RV042 Dual WAN VPN Routers and Cisco Small Business RV042G Dual Gigabit WAN VPN Routers could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected software.
