"The version of Zoom Client for Meetings installed on the remote Windows host is prior to 4.6.19253.0401. It is,
therefore, affected by the following vulnerabilities:

  - A malicious party can use UNC links to leak a user's hashed password.

  - Users can access chat in a webinar when chat is disabled.

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