In this blog, we are going to discuss vulnerable versions of .Net Core. Microsoft releases the information about security breaches in ASP.Net Core. It informs developers which version they need to update to remove this vulnerability. Microsoft is aware of DOS Attack in the OData library. If you are using OData library in your application in the sense attacker can exploit.

We have two types of dependencies in .net core,

  • Direct dependencies
  • transitive dependencies

Direct dependencies are dependencies where you specifically add a package to your project, transitive dependencies occur when you add a package to your project that in turn relies on another package.

Mitigation policy
Open your application through visual studio and go to package manager console and run the below command.
command :-  dotnet --info 

By running the above command you will come to know which package we need to update as per Microsoft security guidelines.
Direct dependencies
By editing your Cs.proj file we can fix the issue or we can update Nuget Package manager.
Transitive dependencies
Transitive dependencies occur when any vulnerable package is referring or relies on another package. By examining the project.asset.json file you can fix the issue.

In this blog, we have discussed vulnerable versions of .Net Core. As per Microsoft security advice it is better to update packages which are in your application.
