"The version of Zoom Client for Meetings installed on the remote host is prior to 5.2.0. It is, therefore, affected by a
vulnerability as referenced in the ZSB-21005 advisory.

  - It was discovered that the installation packages of the Zoom Client for Meetings for macOS (Standard and
    for IT Admin) installation before version 5.2.0, Zoom Client Plugin for Sharing iPhone/iPad before version
    5.2.0, and Zoom Rooms for Conference before version 5.1.0, copy pre- and post- installation shell scripts
    to a user-writable directory. In the affected products listed below, a malicious actor with local access
    to a user's machine could use this flaw to potentially run arbitrary system commands in a higher
    privileged context during the installation process. Users can help keep themselves secure by applying
    current updates or downloading the latest Zoom software with all current security updates from
    https://zoom.us/download. *Changes - 2021-12-14 - Updated description, updated CVSS score, updated CVSS
    vector string, added Zoom Client Plugin for Sharing iPhone/iPad  and Zoom Rooms to the Affected Products
    section. (CVE-2021-34409)

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