Descriptions

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. The vulnerabilities are due to insufficient input validation by the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to an affected device. 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. To exploit these vulnerabilities, an attacker would need to have valid administrator credentials on the affected device.

Múltiples vulnerabilidades en la interfaz de administración basada en web de Enrutadores Cisco Small Business RV110W, RV130, RV130W, y RV215W, podrían permitir a un atacante autenticado remoto conducir ataques de tipo cross-site scripting (XSS) contra un usuario de la interfaz. Las vulnerabilidades son debido a una comprobación insuficiente de entrada por parte de la interfaz de administración basada en web. Un atacante podría explotar estas vulnerabilidades mediante el envío de peticiones HTTP diseñadas hacia un dispositivo afectado. Una explotación con éxito podría permitir al atacante ejecutar código script arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en el navegador. Para explotar estas vulnerabilidades, un atacante necesitaría tener credenciales de administrador válidas en el dispositivo afectado.
