Descriptions
A vulnerability in the REST API of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to perform a command injection attack and elevate privileges to root. This vulnerability is due to insufficient input validation for specific API endpoints. An attacker in a man-in-the-middle position could exploit this vulnerability by intercepting and modifying specific internode communications from one ISE persona to another ISE persona. A successful exploit could allow the attacker to run arbitrary commands with root privileges on the underlying operating system. To exploit this vulnerability, the attacker would need to decrypt HTTPS traffic between two ISE personas that are located on separate nodes.
Una vulnerabilidad en la API REST de Cisco Identity Services Engine (ISE) podría permitir a un atacante remoto no autenticado llevar a cabo un ataque de inyección de comandos y elevar los privilegios a root. Esta vulnerabilidad es debido a una insuficiente comprobación de entradas para determinados endpoints de la API. Un atacante en una posición de tipo "man-in-the-middle" podría explotar esta vulnerabilidad al interceptar y modificar comunicaciones específicas de un personaje de ISE a otro personaje de ISE. Una explotación con éxito podría permitir al atacante ejecutar comandos arbitrarios con privilegios de root en el sistema operativo subyacente. Para explotar esta vulnerabilidad, el atacante tendría que descifrar el tráfico HTTPS entre dos personas ISE que se encuentran en nodos separados
