Descriptions

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) Software could allow an authenticated, remote attacker with administrative credentials to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive, browser-based information. To exploit this vulnerability, an attacker would need valid administrative credentials.

Una vulnerabilidad en la interfaz de administración basada en la web del software Cisco Identity Services Engine (ISE), podría permitir a un atacante autenticado remoto con credenciales administrativas conducir un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz. Esta vulnerabilidad es debido a que la interfaz de administración basada en la web no comprueba apropiadamente las entradas proporcionadas por el usuario. Un atacante podría explotar esta vulnerabilidad inyectando código malicioso en páginas específicas de la interfaz. Una explotación con éxito podría permitir al atacante ejecutar código script arbitrario en el contexto de la interfaz o acceder a información confidencial basada en el navegador. Para explotar esta vulnerabilidad, un atacante necesitaría credenciales administrativas válidas
