Descriptions

A vulnerability in the packet processing functionality of Cisco TelePresence Collaboration Endpoint (CE) Software and Cisco RoomOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted H.323 traffic to an affected device. A successful exploit could allow the attacker to cause the affected device to either reboot normally or reboot into maintenance mode, which could result in a DoS condition on the device.

Una vulnerabilidad en la funcionalidad de procesamiento de paquetes del software Cisco TelePresence Collaboration Endpoint (CE) y del software Cisco RoomOS podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad es debido a una comprobación de entrada insuficiente. Un atacante podría aprovechar esta vulnerabilidad mediante el envío de tráfico H.323 diseñado a un dispositivo afectado. Una explotación con éxito podría permitir al atacante causar que el dispositivo afectado sea reiniciado normalmente o sea reiniciado en modo de mantenimiento, lo que podría resultar en una condición de DoS en el dispositivo
