## 🔑 Hint & Write Up

* Try reading [Dojo-101](https://github.com/Aif4thah/Dojo-101), this project contains all you need to hack this app.

* [Become a sponsor](https://github.com/sponsors/Aif4thah) and get access to the **full methodology** and **complete write-up**.

## ⬇️ Download

```PowerShell
git clone https://github.com/Aif4thah/VulnerableLightApp.git
cd .\VulnerableLightApp\
```

## 🔧🔥 Build and Run

You can use **Dotnet** or **Docker**

### Dotnet

Check `.csproj` file to get the current dotnet version and install [.NET SDK](https://dotnet.microsoft.com/en-us/download)

```PowerShell
dotnet run [--url=<url>]
```

### Docker

```bash
docker build -t vulnerablelightapp .
docker run -p 3000:3000 vulnerablelightapp 
```

### first request

Default : `127.0.0.1:3000`

```sh
curl -k https://127.0.0.1:3000
```

## 🛠️ Debug

### Dotnet install on Linux

Ubuntu / Debian exemple

```bash
wget https://packages.microsoft.com/config/debian/12/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
dpkg -i packages-microsoft-prod.deb
apt update && apt install -y dotnet-sdk-8.0 dotnet-runtime-8.0
```

### Dotnet Framework

Verify you use the intended .NET Framework

```cmd
where dotnet
dotnet --version
dotnet --list-sdks
```

### Certificates

To trust the certificate on windows / mac

```PowerShell
dotnet dev-certs https --trust
```

To generate your cert from Linux :

```sh
#!/bin/bash
openssl req -x509 -newkey rsa:4096 -keyout /app/key.pem -out /app/cert.pem -days 365 -nodes -subj "/CN=localhost"
openssl pkcs12 -export -out /app/cert.pfx -inkey /app/key.pem -in /app/cert.pem -passout pass:mypassword
export ASPNETCORE_Kestrel__Certificates__Default__Path=/app/cert.pfx
export ASPNETCORE_Kestrel__Certificates__Default__Password=mypassword
```

### Dependancies

dependancies have to be dowloaded from [standard sources](https://go.microsoft.com/fwlink/?linkid=848054)

```sh
dotnet nuget add source "https://api.nuget.org/v3/index.json" --name "Microsoft"
```
