      "value": "A vulnerability in the web-based management interface of Cisco Vision Dynamic Signage Director could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface on an affected device. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface. 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 interface or access sensitive, browser-based information."

      "value": "Una vulnerabilidad en la interfaz de administración basada en web de Cisco Vision Dynamic Signage Director podría permitir a un atacante remoto no autenticado realizar un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz en un dispositivo afectado. Esta vulnerabilidad es debido a que la interfaz de administración basada en web no comprueba suficientemente las entradas proporcionadas por el usuario. Un atacante podría explotar esta vulnerabilidad al convencer a un usuario de la interfaz para que haga clic en un enlace diseñado. Una explotación con éxito podría permitir al atacante ejecutar código de script arbitrario en el contexto de la interfaz o acceder a información confidencial basada en el navegador"
