Security Update for Microsoft ASP.NET Core (DoS) (May 2019)

high Nessus Plugin ID 125164


The Microsoft ASP.NET Core installations on the remote host contain vulnerable packages.


The Microsoft ASP.NET Core installation on the remote host is version 2.1.x < 2.1.11, 2.2.x < 2.2.5. It is, therefore, affected by a denial of service (DoS) vulnerability when ASP.NET Core improperly handles web requests. An unauthenticated, remote attacker could exploit this issue, via sending a specially crafted requests to the .NET Core application, to cause the application to stop responding.


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