Descriptions

Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user. These vulnerabilities exist because the web-based management interface does not sufficiently validate user-supplied input. An attacker could exploit these vulnerabilities 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 affected interface or access sensitive, browser-based information. To exploit these vulnerabilities, the attacker would need valid administrative credentials.

Múltiples vulnerabilidades en la interfaz de administración basada en web de Cisco Identity Services Engine (ISE) podrían permitir a un atacante remoto autenticado llevar a cabo un ataque de tipo cross-site scripting (XSS) almacenado contra un usuario. Estas vulnerabilidades se presentan porque la interfaz de administración basada en web no comprueba suficientemente la entrada suministrada por el usuario. Un atacante podría explotar estas vulnerabilidades al inyectar 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 afectada o acceder a información confidencial basada en el navegador. Para explotar estas vulnerabilidades, el atacante necesitaría credenciales administrativas válidas
