Descriptions

A vulnerability in the video endpoint API (xAPI) of Cisco TelePresence Collaboration Endpoint (CE) Software, Cisco TelePresence Codec (TC) Software, and Cisco RoomOS Software could allow an authenticated, remote attacker to conduct directory traversal attacks on an affected device. The vulnerability is due to insufficient validation of user-supplied input to the xAPI of the affected software. An attacker could exploit this vulnerability by sending a crafted request to the xAPI. A successful exploit could allow the attacker to read and write arbitrary files in the system. To exploit this vulnerability, an attacker would need either an In-Room Control or administrator account.

Una vulnerabilidad en la API del endpoint de video (xAPI) de Cisco TelePresence Collaboration Endpoint (CE) Software, Cisco TelePresence Codec (TC) Software, y Cisco RoomOS Software, podría permitir a un atacante remoto autenticado conducir ataques de salto de directorio en un dispositivo afectado. La vulnerabilidad es debido a una comprobación insuficiente de la entrada suministrada por el usuario para la xAPI del software afectado. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición diseñada hacia la xAPI. Una explotación con éxito podría permitir al atacante leer y escribir archivos arbitrarios en el sistema. Para explotar esta vulnerabilidad, un atacante podría necesitar un In-Room Control o una cuenta de administrador
