"The version of Zoom Client for Meetings installed on the remote host is prior to 5.7.3. It is, therefore, affected by a
vulnerability as referenced in the ZSB-21021 advisory.

  - The Zoom Client for Meetings before version 5.7.3 (for Android, iOS, Linux, macOS, and Windows) contain a
    server side request forgery vulnerability in the chat's link preview functionality. In versions prior to
    5.7.3, if a user were to enable the chat's link preview feature, a malicious actor could trick the user
    into potentially sending arbitrary HTTP GET requests to URLs that the actor cannot reach directly. 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-2021-34425)

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