The remote Windows host is missing security update 5026372. It is, therefore, affected by multiple vulnerabilities

  • Windows Pragmatic General Multicast (PGM) Remote Code Execution Vulnerability (CVE-2023-24943)

  • Windows Lightweight Directory Access Protocol (LDAP) Remote Code Execution Vulnerability (CVE-2023-28283)

  • Windows Graphics Component Elevation of Privilege Vulnerability (CVE-2023-24899)

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