Descriptions

A vulnerability in the Embedded Service Router (ESR) of Cisco ISE could allow an authenticated, local attacker to read, write, or delete arbitrary files on the underlying operating system and escalate their privileges to root. To exploit this vulnerability, an attacker must have valid Administrator-level privileges on the affected device. This vulnerability is due to improper privilege management in the ESR console. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to elevate their privileges to root and read, write, or delete arbitrary files from the underlying operating system of the affected device. Note: The ESR is not enabled by default and must be licensed. To verify the status of the ESR in the Admin GUI, choose Administration > Settings > Protocols > IPSec.

Una vulnerabilidad en el router de servicio integrado (ESR) de Cisco ISE podría permitir a un atacante local autenticado leer, escribir o eliminar archivos arbitrarios en el sistema operativo subyacente y escalar sus privilegios a root. Para explotar esta vulnerabilidad, un atacante debe tener privilegios válidos a nivel de administrador en el dispositivo afectado. Esta vulnerabilidad se debe a una gestión inadecuada de privilegios en la consola ESR. Un atacante podría aprovechar esta vulnerabilidad enviando una solicitud manipulada a un dispositivo afectado. Un ataque exitoso podría permitir al atacante elevar sus privilegios a root y leer, escribir o borrar archivos arbitrarios del sistema operativo subyacente del dispositivo afectado. Nota: El ESR no está habilitado por defecto y debe tener licencia. Para comprobar el estado de la ESR en la GUI de administración, seleccione Administración > Configuración > Protocolos > IPSec.
