ShiftLeft C# Example

This repository contains an evolving set of vulnerable .NET applications and some examples for how one can analyze these applications in your CI system, such as:

For more information on how to secure C# applications with ShiftLeft CORE see the documentation at docs.shiftleft.io

Build

Each application has its own folder. You can build using either Visual Studio 2017 or from the command-line using the commands below. In order to build the .NET Framework applications (currently only one, netfwWebapi) you have to have installed Visual Studio 2017 or at least the Visual Studio Build Tools.

Get Source

$ git clone https://github.com/ShiftLeftSecurity/HelloShiftLeft-DotNet-Internal.git

Build All Applications (OUTDATED: will update it soon)

Note: Only the .NET Core applications are buildable and runnable on non-Windows machines.

In a Linux or OS X shell, or a Windows bash shell, you can build the .NET Core applications from a shell:

$ ./buildAll.sh

In a Windows command shell:

> buildAll.cmd

Build Application Individually

    $ cd <application folder>
    $ dotnet build

Run

You can either run an application from within Visual Studio 2017 or directly from the command-line as follows:

.NET Core Console app

   $ cd netcoreConsole/netcoreConsole
   $ dotnet run

The application just prints out a number right now. This may change as we add more functionality.

.NET Core Web API app

   $ cd netcoreWebapi
   $ dotnet run

You will see output to the shell, the last two lines of which are something like this:

Now listening on: http://localhost:8942
Application started. Press Ctrl+C to shut down.

.NET Framework Web API app

Install Internet Information Services (IIS) via Control Panel -> Windows Features if it isn't already installed.

In a browser you can see the app at http://localhost/netfwWebapi

Sensitive Data Leaks in netcoreWebapi

URL	Purpose
http://localhost:8942/api/customers/4343	Returns JSON representation of Customer resource based on Id (4343) specified in URL
http://localhost:8942/api/customers	Returns JSON representation of all available Customer resources
