# 带精确匹配规则的 Web 缓存欺骗
面向 PortSwigger Web Security Academy 实验室的带精确匹配规则的 Web 缓存欺骗笔记，包括利用流程、载荷测试、Burp Suite 验证和修复背景。
### 利用精确匹配缓存规则实施 Web 缓存欺骗
#### 实验目标
* 更改用户电子邮件地址 **administrator**.
* 可用连接： **wiener:peter**.
* 提供了一个分隔符列表：Web 缓存欺骗实验分隔符列表。
#### 观察到的上下文
* 在 **我的账户**，有一个用于更改电子邮件的字段。
* 发送的请求如下：
```bash
email=test%40test.com&csrf=Bfo2p16Es7RG8W0XBZxAJSuyJKOHbK0a
```
#### 分隔符测试
* 通过测试该列表中的字符，网站特别接受：
* 该 **逗点** `;`
* 该 **问号** `?`
经典攻击在此实验中不起作用。
#### 发现隐藏资源
* 从 **目标 -> 站点地图**，使用 **发现内容**.
* 一个 **robots 文件.txt** 出现并且它是 \*\*已缓存\*\*。
#### 通过规范化实现缓存接收（精确路径 + 绕行）
目的：通过让其看起来像一个隐藏资源，强制缓存存储敏感响应。
使用的应用：
```bash
GET /my-account;/../robots.txt
# 编码版本
GET /my-account;%2f%2e%2e%2frobots.txt
```
#### 发送给受害者的利用载荷
{% code overflow="wrap" %}
```javascript
```
{% endcode %}
结果：
* 返回的页面对应于 **管理员账户**.
在答案中，我们获取 **CSRF 令牌** 来自电子邮件表单，例如：
```html
```
#### 计划的最终阶段
* 使用此令牌生成一个 **PoC CSRF** 以发送一个 **POST** 请求到 **我的账户** 电子邮件更改页面，从而更改 **administrator** 电子邮件。
```html
```

## 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/web-cache-deception/web-cache-deception-with-exact-match-rules.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.
