Descriptions

A vulnerability in multiple Cisco Unified Communications and Contact Center Solutions products could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device. This vulnerability is due to the improper processing of user-provided data that is being read into memory. An attacker could exploit this vulnerability by sending a crafted message to a listening port of an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with the privileges of the web services user. With access to the underlying operating system, the attacker could also establish root access on the affected device.

Una vulnerabilidad en múltiples productos Cisco Unified Communications y Contact Center Solutions podría permitir que un atacante remoto no autenticado ejecute código arbitrario en un dispositivo afectado. Esta vulnerabilidad se debe al procesamiento inadecuado de los datos proporcionados por el usuario que se leen en la memoria. Un atacante podría aprovechar esta vulnerabilidad enviando un mensaje manipulado a un puerto de escucha de un dispositivo afectado. Una explotación exitosa podría permitir al atacante ejecutar comandos arbitrarios en el sistema operativo subyacente con los privilegios del usuario de servicios web. Con acceso al sistema operativo subyacente, el atacante también podría establecer acceso root en el dispositivo afectado.
