# 通过版本控制历史进行信息泄露

通过版本控制历史进行信息泄露，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。

### 版本控制历史中的信息泄露

**实验描述**

本实验通过版本控制仓库的历史暴露敏感信息。/ 目标是获取用户的密码 **administrator**，然后使用该账户登录以删除用户 **carlos**.

**初始分析**

通过浏览应用程序，我们看到存在一个目录 **`.git`** 可直接从 Web 服务器访问。

这表明完整的 Git 仓库是公开可见的，可能可以获取源代码和变更历史。

**利用**

**Git 仓库提取**/ 使用 git-dumper 工具下载以下内容的 `.git` 目录：

```bash
git-dumper https://0a7800030384626580b39ee5001e00b1.web-security-academy.net/.git .git
```

**提交历史分析**/ 一旦仓库在本地重建完成，就会查看提交历史：

```bash
git log
```

分析显示某次提交包含删除管理员密码的内容。

**差异检查**/ 查看该提交的具体内容以确定被删除的信息：

```bash
git log -p ab875bcd9cf3ea84ad6af9471521aea4c3a1852d
```

显示的差异使得可以找到用户的密码 **administrator**.

# 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/information-disclosure/information-disclosure-via-version-control-history.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.
