Descriptions

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. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Una vulnerabilidad en la interfaz de administración basada en web de los enrutadores Cisco Small Business RV042 Dual WAN VPN y Cisco Small Business RV042G Dual Gigabit WAN VPN podría permitir que un atacante remoto no autenticado realice un ataque de cross-site scripting (XSS) contra un usuario de la interfaz de administración basada en web de un dispositivo afectado. La vulnerabilidad se debe a una validación insuficiente de la entrada proporcionada por el usuario por parte de la interfaz de administración basada en web del software afectado. Un atacante podría aprovechar esta vulnerabilidad persuadiendo a un usuario de la interfaz para que haga clic en un vínculo creado. Una explotación exitosa podría permitir al atacante ejecutar código de secuencia de comandos arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en el navegador. Cisco ha publicado actualizaciones de software que solucionan esta vulnerabilidad. No existen workarounds que solucionen esta vulnerabilidad.
