Descriptions

A vulnerability in the web management interface of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to perform an unauthorized system reset on an affected device. The vulnerability is due to improper authorization controls for a specific URL in the web management interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could have a twofold impact: the attacker could either change the administrator password, gaining privileged access, or reset the network configuration details, causing a denial of service (DoS) condition. In both scenarios, manual intervention is required to restore normal operations.

Una vulnerabilidad en la interfaz de administración web del Software Cisco AsyncOS para Cisco Web Security Appliance (WSA), podría permitir a un atacante remoto autenticado realizar un reinicio no autorizado del sistema en un dispositivo afectado. La vulnerabilidad es debido a controles de autorización inapropiados para una URL específica en la interfaz de administración web. Un atacante podría explotar esta vulnerabilidad al enviar una petición HTTP diseñada en un dispositivo afectado. Una explotación con éxito podría tener un doble impacto: el atacante podría cambiar la contraseña del administrador, conseguir acceso privilegiado o restablecer los detalles de configuración de red, causando una condición de denegación de servicio (DoS). En ambos escenarios, una intervención manual es requerida para restaurar las operaciones normales.
