Synopsis

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

Description

The Microsoft .NET Core installation on the remote host is version 2.1.x < 2.1.18 or 3.1.x < 3.1.4. It is, therefore, affected by a denial of service vulnerability due to an unspecified flaw related to handling web requests. An unauthenticated, remote attacker could cause denial of service conditions by sending specially crafted web requests.
