"The Windows Remote Desktop client for Windows installed on the remote host is missing security updates. It is, therefore,
affected by multiple vulnerabilities:

  - An information disclosure vulnerability. An attacker can
  exploit this to disclose potentially sensitive
  information. (CVE-2022-22015, CVE-2022-26940)

  - A remote code execution vulnerability. An attacker can
  exploit this to bypass authentication and execute
  unauthorized arbitrary commands. (CVE-2022-22017)

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