Descriptions

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. The vulnerability is due to insufficient validation of user-supplied input to the web-based management interface. An attacker could exploit this vulnerability by crafting a malicious configuration and saving it to the targeted system. An exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information when an administrator views the configuration. An attacker would need write permissions to exploit this vulnerability successfully.

Una vulnerabilidad en la interfaz de administración basada en web de Cisco Identity Services Engine (ISE), podría permitir a un atacante remoto autenticado llevar a cabo un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz basada en web. La vulnerabilidad es debido a una comprobación insuficiente de la entrada suministrada por el usuario en la interfaz de administración basada en web. Un atacante podría explotar esta vulnerabilidad al diseñar una configuración maliciosa y guardarla en el sistema de destino. Una explotación podría permitir al atacante ejecutar código script arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en el navegador cuando un administrador visualiza la configuración. Un atacante necesitaría permisos de escritura para explotar esta vulnerabilidad con éxito.
