## Laravel Tricks
|
|
|
|
### Modo de Depuração
|
|
|
|
Se o Laravel estiver em **modo de depuração**, você poderá acessar o **código** e **dados sensíveis**.\
|
|
Por exemplo `http://127.0.0.1:8000/profiles`:
|
|
|
|
.png>)
|
|
|
|
Isso geralmente é necessário para explorar outras vulnerabilidades de RCE do Laravel.
|
|
|
|
### .env
|
|
|
|
O Laravel salva o APP que ele usa para criptografar os cookies e outras credenciais dentro de um arquivo chamado `.env` que pode ser acessado usando alguma travessia de caminho em: `/../.env`
|
|
|
|
O Laravel também mostrará essas informações na página de depuração (que aparece quando o Laravel encontra um erro e está ativado).
|
|
|
|
Usando a chave secreta APP\_KEY do Laravel, você pode descriptografar e recriptografar cookies:
|
|
|
|
### Descriptografar Cookie
|
|
```python
|
|
import os
|
|
import json
|
|
import hashlib
|
|
import sys
|
|
import hmac
|
|
import base64
|
|
import string
|
|
import requests
|
|
from Crypto.Cipher import AES
|
|
from phpserialize import loads, dumps
|
|
