# 带编码尖括号的属性中反射型 XSS
带编码尖括号的属性中反射型 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 cont
### 带有 HTML 编码尖括号的属性型反射 XSS
此实验室包含一个反射在博客搜索功能中的 XSS 漏洞：用户提供的内容被注入到一个 `值` 一个……的属性 ``，而且 `<` 和 `>` 尖括号在 HTML 中被编码为（`<`, `>`）。目标是注入一个会触发……的新属性 `alert()`.
#### 观察
* 输入的文本会出现在 `值` 输入框的属性中。
* 尝试插入 `">test` 会因对尖括号进行编码而被中和，因此你无法以这种方式打开一个新标签。
```
">test
```
不过，由于该值被引号包围，因此可以闭合该 `值` 值，并向同一个 `` 元素中添加一个新属性，只需注入一个包含结束引号的序列。
```javascript
hola" test="hello
```
1. 闭合 `值` 使用注入的双引号闭合该值。
2. 添加一个新的事件属性（例如 `onmouseover`）其中包含对 `alert()`.
```javascript
test" onmouseover="alert(0)
```
* 有效载荷会闭合该 `值` 属性并添加 `onmouseover="alert(0)"` 到该 `` 元素中。

## 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/xss-reflected-in-an-attribute-with-encoded-angle-brackets.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.
