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 from the underlying operating system. This vulnerability exists because the web-based management interface does not properly validate 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 underlying 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 del sistema operativo subyacente. Esta vulnerabilidad es debido a que la interfaz de administración basada en web no comprueba apropiadamente las entradas proporcionadas por el usuario. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición HTTP diseñada que contenga secuencias de caracteres de salto de ruta a un sistema afectado. Una explotación con éxito podría permitir al atacante acceder a archivos confidenciales en el sistema operativo subyacente
