apache + httpclient4 + jsoup 进行模拟浏览器url访问

Hi,各位好,好久不玩博客了,最近在新公司无聊的时候,在查看一个其他网站的注册源代码时

发现了一处bug

首先前台页面是这样的结构(不显示相关网站的敏感信息)


这是一个很普通的注册页面,ok,我们看看相关js源代码,找到免费获取验证码的功能


这段代码就是普通的校验手机号,然后发送给短信接口api,60秒的校验重复发送,不知道大家发现问题了吗?

我可以根据url恶意仿造这接口需要的参数进行发送手机号码爆破,【(⊙ˍ⊙)# 我都经历了什么。。呃。。】

目标服务器是http请求,那么我们先伪造一个试试【如果js被混淆可以使用Firefox查看post的数据请求及响应(。・_・)/~~~】


下图是直接在浏览器地址栏来进行http访问的


返回的是json数据   中文是Unicode码【Unicode码可以在网站上转换】,该Unicode码是“成功”的意思,同时手机上接收到了短信。

嗯,短信发送过来了,我们是不是该干点什么py交易了呢【(๑•ᴗ•๑),罪恶】

我们可以使用ajax 跨域来访问也可以使用java  apache httpclient来进行模拟浏览器访问


一言不合贴maven【apache httpclient(这里使用的是4.5+版本)和 jsoup(解析html很好用)】

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.2</version>
</dependency>
		
<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.9.1</version>
</dependency>

上代码:http方式模拟访问url

			.split(",");

	}

	public static void post(String url, String number,String ip_proxy) {

		// 创建httppost
		HttpPost httppost = new HttpPost(url);
		httppost.setHeader("Connection","keep-alive");
		httppost.setHeader("Referer","从哪个网站连入过来的");
		httppost.setHeader("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0");
		httppost.setHeader("x-forwarded-for",ip_proxy);//伪造的ip地址
		// 创建参数队列

		} finally {
			// 关闭连接,释放资源
			try {

	}

}

执行获得结果:

--------------------------------------
Response content: {"code":"2000","message":"\u6210\u529f"}
--------------------------------------

循环略..

例子为单线程死循环,如过想搞坏对方的话可以使用多线程,在此不列举多线程的相关知识了,您可以查找相关资料来了解。

PS:不过希望各位观众老爷知道这样做是不对的,以前有过短信接口了解,根据花钱的多少来决定每条短信多少钱,最便宜应该是比分还少的单位,别祸害了网站尴尬

我们从这个例子上发现问题,一个短信接口要做足权限及验证码的验证的【要不钱都被坏人盗刷了_(:зゝ∠)_】

发现了对方的问题,尽量通知到对方的网站管理员或者客服反馈bug。


下面我们在看一个例子:【…(⊙_⊙;)…嘎。还要看吗?】

事件前提:我一个朋友,在一家互联网公司做程序员,辛苦了一年【4个人完成了整个项目,项目卖了2000w+】,到了过年的前几天,无原因突然被辞退,

辛苦了一年,到头来什么也没得到,诶,有这样的领导真是人生寂寞如雪啊。。扯远了,反正就是被强制辞退打包回家活都不用交接直接算账走人。

然后看了看他们的网站注册。。。【咦?为什么还要看网站注册。。= ̄ω ̄=】


注册页面如图:


ok,在看下源代码:


咦,感觉好高端,加上了token。。。

然后在仔细查看这个token的赋值


服务端直接写入js变量里了。。。。


怎么办?感觉好难处理。别急,有jsoup!

jsoup的相关介绍和资料就不在这里写了,请大家自己动手去了解下,我的大概理解就是解析html document对象的,让你方便的获取你想要的信息等(不支持动态的js执行)

我们只要先链接一下该页面并获取到token并把该值传递到发送短信接口的参数里即可实现爆破。

	}
	
}


返回结果:略。

恭喜你,你现在就可以做一个网站爬取的功能了偷笑

从这个问题我们也可以看出,光用token(此例子token纯属摆设)也是不行的,得有一套自己的加密规则和授权才可以


ok,那么看看现在的一些网站的注册页面里的短信发送接口吧。

我们来看一个网站,这个网站的所属公司是上市公司且在美国纳斯达克敲钟的。具体就不多说了

还是看页面


F12大法好



因为url被我除去了,他其实是https的访问

https相关的知识也请各位自行搜索

httpclient如何用https来访问呢?

执行返回结果:略。


其实他有个参数是验证码的参数,只是没有强制带入

同时也看了看各大网站的注册发送短信接口的发送参数,

淘宝的注册可是带都是特定加密信息规则的【(¬_¬)。。你还想干嘛?】

去哪网是带验证码【如果想破解可以了解下ocr图像文字识别技术,安利个开源的一个ocr接口 https://github.com/AvensLab/OcrKing 】


ok,先说这么多吧,再说多就会被请去喝茶聊天了。_(:зゝ∠)_

希望各位也不要乱搞啊。发现bug要发给网站维护人员啊!!!!

还有就是伪造ip那个只是一部分YY而已。他们也是有各种手段来获取到你的真实ip的。

把自己的接口写的茁壮才是正经事诶诶诶!


谢谢各位观众老爷,下次写博客就不知道是什么时候了。o(≧口≦)o

55555~~~图片截图得不行,毕竟csdn没网易邮箱那么智能~截个图就能显示不用存网络了。又重新弄了一次图片下载本地上传。

PS:本想看看csdn短信接口来着,不过他的短信接口已经500了_(:зゝ∠)_
