Descriptions

A Java deserialization vulnerability in Cisco Unity Express (CUE) could allow an unauthenticated, remote attacker to execute arbitrary shell commands with the privileges of the root user. The vulnerability is due to insecure deserialization of user-supplied content by the affected software. An attacker could exploit this vulnerability by sending a malicious serialized Java object to the listening Java Remote Method Invocation (RMI) service. A successful exploit could allow the attacker to execute arbitrary commands on the device with root privileges.

Una vulnerabilidad de deserialización Java en Cisco Unity Express (CUE) podría permitir que un atacante remoto no autenticado ejecute comandos shell arbitrarios con los privilegios del usuario root. La vulnerabilidad se debe a la deserialización no segura por parte del software afectado de contenidos proporcionados por el usuario. Un atacante podría explotar esta vulnerabilidad enviando un objeto Java serializado malicioso al servicio RMI (Remote Method Invocation) Java en escucha. Su explotación con éxito podría permitir que el atacante ejecute comandos arbitrarios en el dispositivo con privilegios root.
