Descriptions

A vulnerability in the web-based management interface of Cisco AsyncOS software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to access sensitive information on an affected device. The vulnerability is due to insufficient validation of requests that are sent to the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request to the interface of an affected device. A successful exploit could allow the attacker to obtain the IP addresses that are configured on the internal interfaces of the affected device. There is a workaround that addresses this vulnerability.

Una vulnerabilidad en la interfaz de administración basada en web en el software de Cisco AsyncOS para Cisco Email Security Appliance (ESA), podría permitir a un atacante remoto no autenticado acceder a información confidencial en un dispositivo afectado. La vulnerabilidad es debido a una comprobación insuficiente de peticiones que son enviadas a la interfaz de administración basada en web. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición diseñada a la interfaz de un dispositivo afectado. Una explotación con éxito podría permitir al atacante obtener las direcciones IP que están configuradas en las interfaces internas del dispositivo afectado. Existe una solución alternativa que soluciona esta vulnerabilidad
