high Nessus Plugin ID 180501

Language:

Synopsis

The remote Windows host is affected by a .NET Core SDK denial-of-service vulnerability.

Description

The version of Microsoft .NET Core SDK installed on the remote host is prior to 7.0.10. It is, therefore, affected by a denial-of-service (DoS) vulnerability. The vulnerability exists in .NET Kestrel where a malicious client can bypass QUIC stream limit in HTTP/3 in both ASP.NET and .NET runtimes resulting in denial of service.

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

Solution

Update .NET Core SDK, remove vulnerable packages and refer to KB5029688.
