# 带被阻止标签的 HTML 中反射型 XSS
带被阻止标签的 HTML 中反射型 XSS 笔记，适用于 PortSwigger Web Security Academy 实验室，包括利用流程、载荷测试、Burp Suite 验证和修复上下文。
### 在大多数标签和属性被阻止的情况下，将反射型 XSS 注入 HTML 上下文
这个实验室的搜索功能中存在反射型 XSS 漏洞，但应用防火墙（WAF）阻止了最常见的 XSS 向量。/ 要完成该实验室，你必须绕过 WAF 并触发 `print()` 函数。
* 尝试诸如以下的经典载荷： `
test
`, `test
* 我用 Burp Suite 拦截了页面，并通过 Intruder 发起了请求。
我复制了事件属性（事件处理程序）的类型，并在 PortSwigger 的速查表中测试了其中几个。
* J
```
```
* 我已经筛选/尝试了几个事件属性，并且我专注于 `onresize`.
```javascript
```
已测试并生效的载荷：
* 直接注入： `` — 通过缩放（鼠标滚轮）会出现 alert。
最终目标：调用 `print()` 而不是 `alert()`:
```javascript
```
发送给受害者的利用 URL：
```javascript
https://0a8500230379f8e980d8032300850075.web-security-academy.net/?search=
```
通过 iframe 投递并自动触发：
* 为了强制 `onresize` 事件在框架中加载，将框架的宽度从其 `onload` 属性：
{% code overflow="wrap" %}
```javascript
```
{% endcode %}
总结：通过注入一个被允许的事件属性（`onresize`）来绕过 WAF，并调用 `print()`，然后通过带有 `onload` 会改变尺寸以触发 `onresize`.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/zh/web/xss/reflected-xss-in-html-with-blocked-tags.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
