## Laravel Tricks
|
|
|
|
### Modo de depuración
|
|
|
|
Si Laravel está en **modo de depuración**, podrás acceder al **código** y a **datos sensibles**.\
|
|
Por ejemplo `http://127.0.0.1:8000/profiles`:
|
|
|
|
.png>)
|
|
|
|
Esto suele ser necesario para explotar otras CVEs de RCE de Laravel.
|
|
|
|
### .env
|
|
|
|
Laravel guarda la APP que utiliza para encriptar las cookies y otras credenciales dentro de un archivo llamado `.env` que se puede acceder utilizando alguna travesía de ruta bajo: `/../.env`
|
|
|
|
Laravel también mostrará esta información dentro de la página de depuración (que aparece cuando Laravel encuentra un error y está activado).
|
|
|
|
Usando la APP\_KEY secreta de Laravel, puedes desencriptar y re-encriptar cookies:
|
|
|
|
### Desencriptar 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
|
|
iv = os.urandom(16)
|
|
#string = dumps(string)
|
|
padding = 16 - len(string) % 16
|
|
string += bytes(chr(padding) * padding, 'utf-8')
|
|

### Laravel Deserialización RCE
|
|
|
|
Versiones vulnerables: 5.5.40 y 5.6.x hasta 5.6.29 ([https://www.cvedetails.com/cve/CVE-2018-15133/](https://www.cvedetails.com/cve/CVE-2018-15133/))
|
|
|
|
Aquí puedes encontrar información sobre la vulnerabilidad de deserialización aquí: [https://labs.withsecure.com/archive/laravel-cookie-forgery-decryption-and-rce/](https://labs.withsecure.com/archive/laravel-cookie-forgery-decryption-and-rce/)
|
|
|
|
Puedes probar y explotarlo usando [https://github.com/kozmic/laravel-poc-CVE-2018-15133](https://github.com/kozmic/laravel-poc-CVE-2018-15133)\
|
|
O también puedes explotarlo con metasploit: `use unix/http/laravel_token_unserialize_exec`
|
|
|
|
### CVE-2021-3129
|
|
|
|
Otra deserialización: [https://github.com/ambionics/laravel-exploits](https://github.com/ambionics/laravel-exploits)
