Descriptions

Cisco Webex Business Suite before 39.1.0 contains a vulnerability that could allow an unauthenticated, remote attacker to affect the integrity of the application. The vulnerability is due to improper validation of host header values. An attacker with a privileged network position, either a man-in-the-middle or by intercepting wireless network traffic, could exploit this vulnerability to manipulate header values sent by a client to the affected application. The attacker could cause the application to use input from the header to redirect a user from the Cisco Webex Meetings Online site to an arbitrary site of the attacker's choosing.

Cisco Webex Business Suite versiones anteriores a 39.1.0, contiene una vulnerabilidad que podría permitir a un atacante no autenticado remoto afectar la integridad de la aplicación. La vulnerabilidad es debido a una comprobación inapropiada de los valores del encabezado del host. Un atacante con una posición de red privilegiada, ya sea de tipo man-in-the-middle o mediante la intercepción del tráfico de la red inalámbrica, podría explotar esta vulnerabilidad para manipular los valores de encabezado enviados por un cliente a la aplicación afectada. El atacante podría causar que la aplicación utilice la entrada del encabezado para redireccionar a un usuario desde el sitio de Cisco Webex Meetings Online hacia un sitio arbitrario de la elección del atacante.

*Credits: Cisco would like to thank Prasenjit Kanti Paul for reporting this vulnerability.
