"The version of Zoom Client for Meetings for Windows installed on the remote host is prior to 5.10.0.  It is,
therefore, affected by multiple vulnerabilities.

  - The Zoom Client for Meetings (for Android, iOS, Linux, MacOS, and Windows) before 
    version 5.10.0 failed to properly parse XML stanzas in XMPP messages. (CVE-2022-22784)
    
  - The Zoom Client for Meetings (for Android, iOS, Linux, MacOS, and Windows) before 
    version 5.10.0 failed to properly constrain client session cookies to Zoom domains.
    (CVE-2022-22785)
    
  - The Zoom Client for Meetings for Windows before version 5.10.0 and Zoom Rooms for 
    Conference Room for Windows before version 5.10.0, fails to properly check the 
    installation version during the update process. (CVE-2022-22786)
    
  - 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. (CVE-2022-22787)

Taken together, these vulnerabilities allow a unauthenticated, remote attacker can exploit this, via stringing these
vulnerabilities together with a MitM attack, to cause Remote Code Execution without any user interaction.

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