The remote Windows host is missing security update 5029304. It is, therefore, affected by multiple vulnerabilities

  • Microsoft Message Queuing Remote Code Execution Vulnerability (CVE-2023-35385, CVE-2023-36910, CVE-2023-36911)

  • Microsoft WDAC OLE DB provider for SQL Server Remote Code Execution Vulnerability (CVE-2023-36882)

  • Windows Bluetooth A2DP driver Elevation of Privilege Vulnerability (CVE-2023-35387)

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