Descriptions

A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to bypass authorization, enabling them to access sensitive information, modify the system configuration, or impact the availability of the affected system. The vulnerability is due to insufficient authorization checking on the affected system. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based management interface of an affected system. A successful exploit could allow the attacker to gain privileges beyond what would normally be authorized for their configured user authorization level. The attacker may be able to access sensitive information, modify the system configuration, or impact the availability of the affected system.

Una vulnerabilidad en la interfaz de administración basada en web del Cisco SD-WAN vManage Software podría permitir a un atacante remoto autenticado omitir la autorización, permitiéndole acceder a información confidencial, modificar la configuración de sistema o afectar la disponibilidad del sistema afectado. La vulnerabilidad es debido a una comprobación de autorización insuficiente en el sistema afectado. Un atacante podría explotar esta vulnerabilidad mediante el envío de peticiones HTTP diseñadas hacia la interfaz de administración basada en web de un sistema afectado. Una explotación con éxito podría permitir al atacante conseguir privilegios más allá de lo que normalmente se autorizaría para su nivel de autorización de usuario configurado. El atacante puede acceder a información confidencial, modificar la configuración de sistema o afectar la disponibilidad del sistema afectado
