Descriptions

A vulnerability in the SOAP API endpoint of Cisco Unified Communications Manager, Cisco Unified Communications Manager Session Management Edition, Cisco Unified Communications Manager IM & Presence Service, Cisco Unity Connection, and Cisco Prime License Manager could allow an authenticated, remote attacker to execute arbitrary code on an affected device. This vulnerability is due to improper sanitization of user-supplied input. An attacker could exploit this vulnerability by sending a SOAP API request with crafted parameters to an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges on the underlying Linux operating system of the affected device.

Una vulnerabilidad en el endpoint de la API SOAP de Cisco Unified Communications Manager, Cisco Unified Communications Manager Session Management Edition, Cisco Unified Communications Manager IM & amp; Presence Service, Cisco Unity Connection y Cisco Prime License Manager, podrían permitir a un atacante remoto autenticado ejecutar código arbitrario en un dispositivo afectado. Esta vulnerabilidad es debido a un saneamiento inapropiado de la entrada suministrada por el usuario. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición de API SOAP con parámetros diseñados hacia un dispositivo afectado. Una explotación con éxito podría permitir al atacante ejecutar código arbitrario con privilegios root en el sistema operativo Linux subyacente del dispositivo afectado
