Descriptions

A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) could allow an authenticated, remote attacker to read arbitrary files on the underlying operating system of an affected device. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to access sensitive files on the operating system.

Una vulnerabilidad en la interfaz de administración basada en web de Cisco Unified Communications Manager (Unified CM) y Cisco Unified Communications Manager Session Management Edition (Unified CM SME) podría permitir a un atacante remoto autenticado leer archivos arbitrarios en el sistema operativo subyacente de un dispositivo afectado. Esta vulnerabilidad es debido a que no es comprobada correctamente la entrada proporcionada por el usuario. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición HTTP diseñada que contenga secuencias de caracteres para saltar directorios a un sistema afectado. Una explotación con éxito podría permitir al atacante acceder a archivos confidenciales en el sistema operativo
