The remote Windows host is missing security update 5028166. It is, therefore, affected by multiple vulnerabilities

  • Windows Routing and Remote Access Service (RRAS) Remote Code Execution Vulnerability (CVE-2023-35365, CVE-2023-35366, CVE-2023-35367)

  • Windows Netlogon Information Disclosure Vulnerability (CVE-2023-21526)

  • Windows Win32k Elevation of Privilege Vulnerability (CVE-2023-21756)

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