"value": "Una vulnerabilidad en Cisco Webex Network Recording Player y Cisco Webex Player para Microsoft Windows, podría permitir a un atacante causar un bloqueo del proceso resultando en una condición de Denegación de servicio (DoS) para la aplicación del reproductor sobre un sistema afectado. La vulnerabilidad se presenta debido a una comprobación insuficiente de determinados elementos con una grabación de Webex almacenada en Advanced Recording Format (ARF) o en Webex Recording Format (WRF). Un atacante podría explotar esta vulnerabilidad al enviar a un usuario un archivo ARF o WRF malicioso por medio de un enlace o archivo adjunto de correo electrónico y persuadiendo a un usuario de abrir el archivo con el software afectado en el sistema local. Una explotación con éxito podría permitir a un atacante causar que la aplicación del reproductor Webex se bloquee cuando tratan de visualizar el archivo malicioso."
