"The Microsoft Exchange Server installed on the remote host is missing security updates. It is, therefore, affected by 
multiple vulnerabilities including the following:

  - A remote code execution vulnerability exists in Exchange. An authenticated, remote attacker can exploit this to 
    bypass authentication and execute arbitrary commands (CVE-2022-23277).

  - An information disclosure vulnerability exists in Exchange. An authenticated, remote attacker can exploit this 
    to disclose the contents of files on the exchange server (CVE-2022-24463).

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