PHP、MySQL 注入

Welcome to the NetSPI SQL Injection Wiki：https://sqlwiki.netspi.com/

因为需要了解下 SQL 注入，就使用 PHP 自己写了一个只有一个网页的网站测试下，现在记录下过程。。。

直接使用的 KALI系统 (KALI官网：Kali Linux | Penetration Testing and Ethical Hacking Linux Distribution)。KALI 是一个渗透测试的神器。集成了好多黑客工具，当然也就集成了许多开发所需的环境。

这里只涉及 MySQL 和 apache

启动 MySQL :

root@kali:~# systemctl start mysql      //启动 mysql 服务
root@kali:~# systemctl status mysql     //查看 mysql 状态

SQL 建表脚本(添加一些测试数据)：

启动 apache

root@kali:~# systemctl start apache2
root@kali:~# systemctl status apache2

apache 的默认主页是 /var/www/html/index.html。直接访问 http://localhost/index.html

修改 index.html 为 index.php

index.php 内容如下：（数据库连接部分参考：https://www.runoob.com/php/php-pdo.html）

<?php 
ini_set("display_errors", "On");
error_reporting(E_ALL | E_STRICT);print('Hello '); // 输出 "Hello " 并且没有换行符
echo "World\n";  // 输出 "World" 并且换行
echo "<br />";
echo "<hr />";
