Security Update for Microsoft .NET Core (October 2024)

high Nessus Plugin ID 208286

Synopsis

The remote Windows host is affected by a .NET Core vulnerability

Description

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the vendor advisory.

- .NET and Visual Studio Remote Code Execution Vulnerability (CVE-2024-38229)

- .NET and Visual Studio Denial of Service Vulnerability (CVE-2024-43483,CVE-2024-43484,CVE-2024-43485)

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

Solution

Update .NET Core, remove vulnerable packages and refer to vendor advisory.
