mysql注入kali

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 />";

$pass='';           //对应的密码
$dsn="$dbms:host=$host;dbname=$dbName";
 
try {
    // 连接到数据库
    $dbh = new PDO($dsn, $user, $pass);  
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);  
    $dbh->exec('set names utf8'); 
    echo "连接成功<br/>";
    // sql 语句
    $strsql="SELECT id,name,countrycode FROM `City` LIMIT 5";
    //你还可以进行一次搜索操作
    foreach ($dbh->query($strsql) as $row) {
        //print_r($row); //你可以用 echo($GLOBAL); 来看到这些值
        echo "id: {$row['id']}        ";
        echo "name: {$row['name']}        ";
        echo "countrycode: {$row['countrycode']}        ";
        echo "<br />";
    }
    $dbh = null;

    die ("Error!: " . $e->getMessage() . "<br/>");

浏览器直接访问：http://localhost/index.php

mysql 数据库中结果

到此，我的第一个 php 程序结束。。。。。

一个简单的 SQL 注入验证

输入要查询的 ID (数字)，点击 search 按钮，注意浏览器 url 变化，传递一个参数 search=1 。然后下面显示查询结果。

现在修改 URL 传递的参数。

修改后的 URL 为：http://localhost/index.php?search=1 or '1'='1'&submit=Search

再来一个复杂点的 SQL 注入验证:

URL：http://localhost/index.php?search=1 union select code,name,region from Country LIMIT 5;&submit=Search

一个读取文件的 SQL 注入

至此，一个简单的 SQL 注入验证完成。SQL 注入不止这些东西，以后慢慢学习研究。。。
