"The version of Dell EMC NetWorker installed on the remote Windows host is 19.2.1.x, 19.3.x, 19.4.x 19.5.x 19.6.x
prior to 19.6.1.2 or 19.7.0.0. It is, therefore, affected by a privilege escalation vulnerability. An authenticated,
non-administrative attacker can exploit this vulnerability to gain access to restricted resources.

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