## Laravel Tricks
|
|
|
|
### Debugging mode
|
|
|
|
If Laravel is in **debugging mode** you will be able to access the **code** and **sensitive data**.\
|
|
For example `http://127.0.0.1:8000/profiles`:
|
|
|
|
.png>)
|
|
|
|
This is usually needed for exploiting other Laravel RCE CVEs.
|
|
|
|
### .env
|
|
|
|
Laravel saves the APP it uses to encrypt the cookies and other credentials inside a file called `.env` that can be accessed using some path traversal under: `/../.env`
|
|
|
|
Laravel will also show this information inside the debug page (that appears when Laravel finds an error and it's activated).
|
|
|
|
Using the secret APP\_KEY of Laravel you can decrypt and re-encrypt cookies:
|
|
|
|
### Decrypt 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

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

|
|
#string = dumps(string)
|
|

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

### Laravel Deserialization RCE
|
|
|
|
Vulnerable versions: 5.5.40 and 5.6.x through 5.6.29 ([https://www.cvedetails.com/cve/CVE-2018-15133/](https://www.cvedetails.com/cve/CVE-2018-15133/))
|
|
|
|
Here you can find information about the deserialization vulnerability here: [https://labs.withsecure.com/archive/laravel-cookie-forgery-decryption-and-rce/](https://labs.withsecure.com/archive/laravel-cookie-forgery-decryption-and-rce/)
|
|
|
|
You can test and exploit it using [https://github.com/kozmic/laravel-poc-CVE-2018-15133](https://github.com/kozmic/laravel-poc-CVE-2018-15133)\
|
|
Or you can also exploit it with metasploit: `use unix/http/laravel_token_unserialize_exec`
|
|
|
|
### CVE-2021-3129
|
|
|
|
Another deserialization: [https://github.com/ambionics/laravel-exploits](https://github.com/ambionics/laravel-exploits)
