The version of Zoom Client for Meetings installed on the remote host is prior to 5.10.0. It is, therefore, affected by a vulnerability as referenced in the ZSB-22009 advisory.

  • The Zoom Client for Meetings (for Android, iOS, Linux, macOS, and Windows) before version 5.10.0 fails to properly validate the hostname during a server switch request. This issue could be used in a more sophisticated attack to trick an unsuspecting user’s client to connect to a malicious server when attempting to use Zoom services. 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.
    (CVE-2022-22787)

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