"The version of the Zoom Client installed on the remote host is between 5.7.3 and 5.11.5. It is, therefore, affected by
a privilege escalation vulnerability in the auto-update process. A local low-privileged user could exploit this 
vulnerability to escalate their privileges to root.

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