"According to its self-reported version, the Cisco Prime Infrastructure application running on the remote host is
2.2(2.0.78) prior to 3.1(2.0.0) or 3.5(0.0) prior to 3.5(1). It is, therefore, affected by a privilege escalation
vulnerability in the Virtual Domain system due to improper validation of API requests. An authenticated, remote
attacker can exploit this by sending a crafted request to the server in order to change the virtual domain
configuration and possibly elevate privileges.");
