The remote Windows host is missing security update 5031354. It is, therefore, affected by multiple vulnerabilities

  - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation     can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

  - Microsoft QUIC Denial of Service Vulnerability (CVE-2023-36435, CVE-2023-38171)   
  - Microsoft WDAC OLE DB provider for SQL Server Remote Code Execution Vulnerability (CVE-2023-36577)

  - Windows IIS Server Elevation of Privilege Vulnerability (CVE-2023-36434)

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

The version of Microsoft .NET Core SDK installed on the remote host is 6.0.x prior to 6.0.123, 6.0.x prior to 6.0.318, 6.0.x prior to 6.0.414, 7.0.x prior to 7.0.112 or 7.0.x prior to 7.0.309 or 7.0.x prior to 7.0.402.
It is, therefore, affected by multiple vulnerabilities, as follows:

  - A vulnerability exists in the ASP.NET Core Kestrel web server where a malicious client may flood the   server with specially crafted HTTP/2 requests, causing denial of service. (CVE-2023-44487)   
  - A null pointer vulnerability exists in MsQuic.dll which may lead to Denial of Service. This issue only   affects Windows systems. (CVE-2023-38171)

  - A memory leak vulnerability exists in MsQuic.dll which may lead to Denial of Service. This issue only   affects Windows systems. (CVE-2023-36435)

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

The version of Microsoft .NET 7 Core installed on the remote host is prior to 7.0.12. It is, therefore, affected by multiple vulnerabilities as referenced in the 2023_Oct_10 advisory.

The Microsoft Visual Studio Products are missing security   updates. It is, therefore, affected by multiple denial of   service vulnerabilities:
    - A denial of service (DoS) vulnerability. An attacker can       exploit this issue to cause the affected component to       deny system or application services. (CVE-2023-38171)

    - The HTTP/2 protocol allows a denial of service (server       resource consumption) because request cancellation can       reset many streams quickly (CVE-2023-44487)
