Cisco Unified Contact Center Express Remote Code Execution Vulnerability

A vulnerability in the Java Remote Method Invocation (RMI) process of Cisco Unified CCX could allow an unauthenticated, remote attacker to upload arbitrary files and execute arbitrary commands with root permissions on an affected system. This vulnerability is due to improper authentication mechanisms that are associated to specific Cisco Unified CCX features. An attacker could exploit this vulnerability by uploading a crafted file to an affected system through the Java RMI process. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root.
