These vulnerabilities are due to insufficient validation of user fields within incoming HTTP packets. An attacker could exploit these vulnerabilities by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device with root-level privileges or to cause the device to restart unexpectedly, resulting in a DoS condition. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device. Cisco has not released software updates that address these vulnerabilities."}, {"lang": "es", "value": "M\u00faltiples vulnerabilidades en la interfaz de administraci\u00f3n basada en la web de los routers Cisco Small Business versiones RV110W, RV130, RV130W y RV215W podr\u00edan permitir a un atacante autenticado y remoto ejecutar c\u00f3digo arbitrario en un dispositivo afectado o causar que el dispositivo sea reiniciado inesperadamente, resultando en una condici\u00f3n de denegaci\u00f3n de servicio (DoS).
