Descriptions

A vulnerability in the web framework code of Cisco IOS and Cisco IOS XE Software could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web interface of the affected software using the banner parameter. The vulnerability is due to insufficient input validation of the banner parameters that are passed to the web server of the affected software. An attacker could exploit this vulnerability by crafting a banner parameter and saving it. The attacker could then convince a user of the web interface to access a malicious link or could intercept a user request for the affected web interface and inject malicious code into the request. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected web interface or allow the attacker to access sensitive browser-based information.

Una vulnerabilidad en el código del framework web de los Software Cisco IOS y Cisco IOS XE, podría permitir a un atacante remoto autenticado realizar un ataque de tipo cross-site scripting (XSS) almacenado contra un usuario de la interfaz web del software afectado usando el parámetro banner. La vulnerabilidad es debido a una comprobación de entrada insuficiente de los parámetros banner que son pasados hacia el servidor web del software afectado. Un atacante podría explotar esta vulnerabilidad mediante el diseño de un parámetro de banner y guardarlo. El atacante podría convencer a un usuario de la interfaz web para acceder a un enlace malicioso o podría interceptar una petición del usuario para la interfaz web afectada e inyectar código malicioso en la petición. Una explotación con éxito podría permitir al atacante ejecutar código script arbitrario en el contexto de la interfaz web afectada o permitir al atacante acceder a información confidencial basada en navegador.
