"The version of Cisco Unity Connection installed on the remote device is version 12.5(1) prior to 12.5(1)SU6 or 14
prior to 14SU1. It is, therefore, affected by a timing attack due to insufficient protection of a system password.
An unauthenticated remote attacker can exploit this vulnerability to determine a sensitive system password.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
