How to Install and Use GVM Vulnerability Scanner on Ubuntu 20.04

GVM also called "Greenbone Vulnerability Management" is an open-source vulnerability scanning and management software that provides a set of network vulnerability tests to find security loopholes in systems and applications. This is an all-in-one suite of tools used by many security experts and normal users around the world.

In this tutorial, we will show you how to install and configure GVM on Ubuntu 20.04 server.

Prerequisites

  • A server running Ubuntu 20.04.
  • A root password is configured the server.

Getting Started

Before starting, you will need to update your system packages to the latest version. You can update them using the following command:

apt-get update -y

Once your server is updated, you can proceed to the next step.

Install Required Dependencies

Before starting, you will need to install all required dependencies in your system. You can install them by running the following command:

apt-get install software-properties-common build-essential cmake pkg-config libglib2.0-dev libgpgme-dev libgnutls28-dev uuid-dev libssh-gcrypt-dev libldap2-dev doxygen graphviz libradcli-dev libhiredis-dev libpcap-dev bison libksba-dev libsnmp-dev gcc-mingw-w64 heimdal-dev libpopt-dev xmltoman redis-server xsltproc libical-dev gnutls-bin nmap rpm nsis curl wget fakeroot gnupg sshpass socat snmp smbclient libmicrohttpd-dev libxml2-dev python3-polib gettext rsync xml-twig-tools python3-paramiko python3-lxml python3-defusedxml python3-pip python3-psutil python3-impacket virtualenv vim git texlive-latex-extra texlive-fonts-recommended -y

Once all the dependencies are installed, add the Yarn repository to your system:

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list

Next, update the repository and install the Yarn package with the following command:

apt-get update -y
apt-get install yarn -y

Next, upgrade Yarn to the latest version using the following command:

yarn install
yarn upgrade

Once you are finished, you can proceed to the next step.

Install and Configure PostgreSQL

GVM uses the PostgreSQL as a database backend so you will need to install the PostgreSQL server to your system. You can install it with the following command:

apt-get install postgresql postgresql-contrib postgresql-server-dev-all -y

Once the installation has been finished, log in to PostgreSQL and create a user and database for GVM:

sudo -u postgres bash
export LC_ALL="C"
createuser -DRS gvm
createdb -O gvm gvmd

Next, connect to database then create a role and extensions with the following command:

psql gvmd
create role dba with superuser noinherit;
grant dba to gvm;
create extension "uuid-ossp";
create extension "pgcrypto";

Next, exit from the PostgreSQL with the following command:

exit
exit

Download GVM

First, create a separate directory and user for GVM with the following command:

mkdir /opt/gvm
adduser gvm --disabled-password --home /opt/gvm/ --no-create-home --gecos ''

Next, add a redis user to GVM and set proper permission with the following command:

usermod -aG redis gvm
chown gvm:gvm /opt/gvm/

Next, create a path variable for GVM with the following command:

echo 'export PATH="$PATH:/opt/gvm/bin:/opt/gvm/sbin:/opt/gvm/.local/bin"' | tee -a /etc/profile.d/gvm.sh
chmod 0755 /etc/profile.d/gvm.sh
source /etc/profile.d/gvm.sh

Next, define the GVM library path using the following command:

nano /etc/ld.so.conf.d/gvm.conf

Add the following line:

/opt/gvm/lib

Next, log in to GVM user and create a directory for all components:

su - gvm
mkdir src

Next, download all the required components inside src directory with the following command:

cd src
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH
git clone -b gvm-libs-20.08 --single-branch https://github.com/greenbone/gvm-libs.git
git clone -b openvas-20.08 --single-branch https://github.com/greenbone/openvas.git
git clone -b gvmd-20.08 --single-branch https://github.com/greenbone/gvmd.git
git clone -b master --single-branch https://github.com/greenbone/openvas-smb.git
git clone -b gsa-20.08 --single-branch https://github.com/greenbone/gsa.git
git clone -b ospd-openvas-20.08 --single-branch https://github.com/greenbone/ospd-openvas.git
git clone -b ospd-20.08 --single-branch https://github.com/greenbone/ospd.git

Install gvm-libs

Next, change the directory to gvm-libs, export the config path and create a build directory with the following command:

cd gvm-libs
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH
mkdir build

Next, change the directory to build and compile the gvm-libs using the following command:

cd build
cmake -DCMAKE_INSTALL_PREFIX=/opt/gvm ..
make
make doc
make install

Install openvas-smb

Next, change the directory to openvas-smb, export the config path and create a build directory with the following command:

cd /opt/gvm/src
cd openvas-smb
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH
mkdir build

Next, change the directory to build and compile the openvas-smb with the following command:

cd build
cmake -DCMAKE_INSTALL_PREFIX=/opt/gvm ..
make
make install

Install OpenVAS Scanner

Next, change the directory to openvas, export the config path and create a build directory with the following command:

cd /opt/gvm/src
cd openvas
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH
mkdir build

Next, change the directory to build and install the OpenVAS scanner with the following command:

cd build
cmake -DCMAKE_INSTALL_PREFIX=/opt/gvm ..
make
make doc
make install

Next, exit from the gvm user with the following command:

exit

Next, create the cache to the installed shared libraries with the following command:

export LC_ALL="C"
ldconfig

Next, copy OpenVAS scanner Redis configuration file with the following command:

cp /etc/redis/redis.conf /etc/redis/redis.orig
cp /opt/gvm/src/openvas/config/redis-openvas.conf /etc/redis/

Next, set proper ownership with the following command:

chown redis:redis /etc/redis/redis-openvas.conf

Next, update the path to Redis unix socket with the following command:

echo "db_address = /run/redis-openvas/redis.sock" > /opt/gvm/etc/openvas/openvas.conf

Next, enable and start the Redis service with the following command:

systemctl enable [email protected]
systemctl start [email protected]

Next, you will need to tweak the sysctl.conf file. You can do it with the following command:

sysctl -w net.core.somaxconn=1024 
sysctl vm.overcommit_memory=1
echo "net.core.somaxconn=1024" >> /etc/sysctl.conf
echo "vm.overcommit_memory=1" >> /etc/sysctl.conf

Next, reload the sysctl with the following command:

sysctl -p

Create Systemd Service File

First, create a systemd service file for Transparent Huge Pages (THP) with the following command:

nano /etc/systemd/system/disable-thp.service

Add the following lines:

Description=Disable Transparent Huge Pages (THP)

[Service]
Type=simple
ExecStart=/bin/sh -c "echo 'never' > /sys/kernel/mm/transparent_hugepage/enabled && echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag"

[Install]
WantedBy=multi-user.target

Save and close the file then reload the systemd service with the following command:

systemctl daemon-reload

Next, start the disable-thp service and enable it to start at system reboot:

systemctl start disable-thp 
systemctl enable disable-thp

Next, restart the Redis service to apply the changes:

systemctl restart redis-server

Next, you will need to grant the gvm user to run all system command using sudo without providing a password. You can do it with the following command:

sed 's/Defaults\s.*secure_path=\"\/usr\/local\/sbin:\/usr\/local\/bin:\/usr\/sbin:\/usr\/bin:\/sbin:\/bin:\/snap\/bin\"/Defaults secure_path=\"\/usr\/local\/sbin:\/usr\/local\/bin:\/usr\/sbin:\/usr\/bin:\/sbin:\/bin:\/snap\/bin:\/opt\/gvm\/sbin\"/g' /etc/sudoers | EDITOR='tee' visudo
echo "gvm ALL = NOPASSWD: /opt/gvm/sbin/openvas" > /etc/sudoers.d/gvm
echo "gvm ALL = NOPASSWD: /opt/gvm/sbin/gsad" >> /etc/sudoers.d/gvm

Update NVTs

Next, you will need to update Network Vulnerability Tests feed from Greenbone Security Feed/Community Feed.

First, log in to gvm user with the following command:

su - gvm

Next, update the feed with the following command:

greenbone-nvt-sync

Once the update is completed, update Redis server with the same VT info from VT files:

sudo openvas --update-vt-info

Install Greenbone Vulnerability Manager

First, change the directory to gvmd, export the config path and create a build directory with the following command:

cd /opt/gvm/src/gvmd 
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH
mkdir build

Next, change the directory to build and install the gvmd with the following command:

cd build/ 
cmake -DCMAKE_INSTALL_PREFIX=/opt/gvm ..
make
make doc
make install

Next, fix certificate with the following command:

gvm-manage-certs -a

Configure and Update Feeds (GVM)

First, create an admin user to access the GVM web interface:

gvmd --create-user=admin --password=admin

Next, find the UUID of an admin user with the following command:

gvmd --get-users --verbose

You should get the following output:

admin 1288cbcf-23a0-407f-8013-b7a57acc5795

Next, modify the gvmd settings with the user UUID:

gvmd --modify-setting 78eceaec-3385-11ea-b237-28d24461215b --value 1288cbcf-23a0-407f-8013-b7a57acc5795

Next, sync all greenbone feeds with the following command:

greenbone-feed-sync --type GVMD_DATA
greenbone-feed-sync --type SCAP
greenbone-feed-sync --type CERT

Install gsa

First, change the directory to gsa, export the config path and create a build directory with the following command:

cd /opt/gvm/src/gsa 
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH
mkdir build

Next, change the directory to build and install the gsa with the following command:

cd build/ 
cmake -DCMAKE_INSTALL_PREFIX=/opt/gvm ..
make
make doc
make install

Next, create a log file for gsa with the following command:

virtualenv --python python3.8 /opt/gvm/bin/ospd-scanner/

Next, activate the virtual environment with the following command:

source /opt/gvm/bin/ospd-scanner/bin/activate

Next, create a directory for ospd with the following command:

mkdir /opt/gvm/var/run/ospd/

Next, change the directory to ospd and install ospd with pip:

cd ospd 
pip3 install .

Next, change the directory to ospd-openvas and install the ospd-openvas using the pip command:

cd /opt/gvm/src/ospd-openvas
pip3 install .

Next, exit from the gvm user with the following command:

exit

Create a Systemd Service File for GVM, GSAD and OpenVAS

First, create a systemd service file for gvmd with the following command:

nano /etc/systemd/system/gvmd.service

Add the following lines:

[Unit]

Very nice guide. Thank you

By: ustoopia

Will this system also be able to scan other machines? Or is it just for scanning the localhost?

By: Tobe

Great tutorial, thanks for that.I wan't add / correct two points which not worked for me:1.  Installation process for yarn changed a bit. First I had to install npm and then install yarn with it:apt-get install npmnpm install -g yarnmkdir /opt/gvmcd /opt/gvm/usr/local/lib/node_modules/yarn/bin/yarn set version berry/usr/local/lib/node_modules/yarn/bin/yarn set version latest2. There's a wrong path to the ospd.sock in the last command in the how to (Now, modify the default scanner using the above UUID). It should be gvmd --modify-scanner=08b69003-5fc2-4037-a479-93b440211c73 --scanner-host=/opt/gvm/var/run/ospd.sock

By: cesare

Hi, thank you.

But I'm stuck on the yarn installation.

This line is not working for me:

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list

It says:

Warning: apt-key output should not be parsed (stdout is not a terminal) gpg: can't open 'echo': File o directory non esistente gpg: can't open 'deb https://dl.yarnpkg.com/debian/ stable main': File o directory non esistente

 

Could you tell me exacly write how to install it?I've read on Tobe comment I need to:- apt-get install npmnpm

I would appreciate to know exacly what to do (sorry but I'm not an exper Ubuntu user...)

Thanks,Cesare

By: Tobe

Sorry, my formatting got lost.

Apt-get install npm

npm install -g yarn

mkdir /opt/gvm

cd /opt/gvm

yarn set version berry

yarn set version latest

 

If you get an error about the node version do the following:

 

sudo npm cache clean -f

sudo npm install -g n

sudo n 14.2

yarn set version latest

 

An very important: Do not install PostgreSQL 12, but rather 11. It is a known issue, that GVM is very slow with PostgreSQL 12. That's the reason I'm reinstalling it at the moment.

By: Anold

Is there any way to scan other computers that is in a different network environment? Thank you!

By: ustoopia

Any chance you could remove 'use' from the title of this article as you don't show us how to us gvm. I have already installed GVM but haven't managed to get any results on a target with known vulnerabilitites.
