Descriptions

A vulnerability in an API endpoint of Cisco ACI Multi-Site Orchestrator (MSO) installed on the Application Services Engine could allow an unauthenticated, remote attacker to bypass authentication on an affected device. The vulnerability is due to improper token validation on a specific API endpoint. An attacker could exploit this vulnerability by sending a crafted request to the affected API. A successful exploit could allow the attacker to receive a token with administrator-level privileges that could be used to authenticate to the API on affected MSO and managed Cisco Application Policy Infrastructure Controller (APIC) devices.

Una vulnerabilidad en un endpoint de la API de Cisco ACI Multi-Site Orchestrator (MSO) instalado en Application Services Engine, podría permitir a un atacante remoto no autenticado omitir la autenticación en un dispositivo afectado. La vulnerabilidad es debido a una comprobación de token incorrecta en un endpoint de la API específico. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición diseñada a la API afectada. Una explotación con éxito podría permitir que el atacante reciba un token con privilegios de nivel de administrador que podría ser usado para autenticarse en la API en un MSO afectado y dispositivos Cisco Application Policy Infrastructure Controller (APIC) administrados
