Descriptions

A vulnerability in an API endpoint of Cisco Application Policy Infrastructure Controller (APIC) and Cisco Cloud Application Policy Infrastructure Controller (Cloud APIC) could allow an authenticated, remote attacker to elevate privileges to Administrator on an affected device. This vulnerability is due to an improper policy default setting. An attacker could exploit this vulnerability by using a non-privileged credential for Cisco ACI Multi-Site Orchestrator (MSO) to send a specific API request to a managed Cisco APIC or Cloud APIC device. A successful exploit could allow the attacker to obtain Administrator credentials on the affected device.

Una vulnerabilidad en un endpoint de la API de Cisco Application Policy Infrastructure Controller (APIC) y Cisco Cloud Application Policy Infrastructure Controller (Cloud APIC) podría permitir a un atacante remoto autenticado elevar los privilegios a Administrador en un dispositivo afectado. Esta vulnerabilidad es debido a una configuración inapropiada de la política predeterminada. Un atacante podría explotar esta vulnerabilidad al usar una credencial sin privilegios para Cisco ACI Multi-Site Orchestrator (MSO) para enviar una petición de API específica a un dispositivo manejado por Cisco APIC o Cloud APIC. Una explotación con éxito podría permitir al atacante obtener credenciales de Administrador en el dispositivo afectado.
