开始前的小准备

upload-labs靶场是PHP环境运行的,所以我准备了一个PHP脚本和一张图片 图片好准备,PHP脚本如果不想写的话可以用我的这个获取当前时间的PHP脚本

<?php

header("content-type:text/html;charset=utf-8");

date_default_timezone_set("PRC");//设置时区

echo "当前时间为：";

$today = date("Y-m-d D h:i:s A ");

echo $today;

?>

图片默认不清楚放大看!!!

Pass-10

代码:

$is_upload = false;
$msg = null;
if (isset($_POST['submit'])) {
    if (file_exists(UPLOAD_PATH)) {
        $deny_ext = array("php","php5","php4","php3","php2","html","htm","phtml","pht","jsp","jspa","jspx","jsw","jsv","jspf","jtml","asp","aspx","asa","asax","ascx","ashx","asmx","cer","swf","htaccess");

        $file_name = trim($_FILES['upload_file']['name']);
        $file_name = str_ireplace($deny_ext,"", $file_name);
        $temp_file = $_FILES['upload_file']['tmp_name'];
        $img_path = UPLOAD_PATH.'/'.$file_name;        
        if (move_uploaded_file($temp_file, $img_path)) {
            $is_upload = true;
        } else {
            $msg = '上传出错！';
        }
    } else {
        $msg = UPLOAD_PATH . '文件夹不存在,请手工创建！';
    }
}
