The Microsoft .NET Core installation on the remote host is version 2.1.x < 2.1.13, or 2.2.x < 2.2.7. It is, therefore, affected by a denial-of-service vulnerability when .Net Core improperly handles web requests. An unauthenticated, remote attacker could exploit this issue, to cause a denial of service attack against a .Net Core web application.
