Installation

gvm

The Greenbone Vulnerability Manager is a modular security auditing tool, used for testing remote systems for vulnerabilities that should be fixed.

This package installs all the required packages. It provides scripts to setup, start and stop the GVM services.

The tool was previously named OpenVAS.

Installed size: 48 KB

How to install: sudo apt install gvm

  Test completeness and readiness of GVM-22.4.0
Step 1: Checking OpenVAS (Scanner)... 
        OK: OpenVAS Scanner is present in version 22.4.0.
        OK: Notus Scanner is present in version 22.4.1.
        OK: Server CA Certificate is present as /var/lib/gvm/CA/servercert.pem.
Checking permissions of /var/lib/openvas/gnupg/*
        OK: _gvm owns all files in /var/lib/openvas/gnupg
        OK: redis-server is present.
        OK: scanner (db_address setting) is configured properly using the redis-server socket: /var/run/redis-openvas/redis-server.sock
        ERROR: redis-server is not running or not listening on socket: /var/run/redis-openvas/redis-server.sock
        FIX: You should start the redis-server with 'systemctl start redis-server@openvas.service' or configure it to listen on socket: /var/run/redis-openvas/redis-server.sock

 ERROR: Your GVM-22.4.0 installation is not yet complete!

Please follow the instructions marked with FIX above and run this

OpenVAS Usage Examples

Before trying to do anything with OpenVAS, you must first run the setup script, appropriately named openvas-setup. At the end of the (very long) setup process, the automatically created password will be displayed to you. Save the password somewhere safe.

After the setup completes, you will find two listening TCP ports

9390 and 9392

Port 9392 is likely the one of most interest to you as it is the web interface for OpenVAS. You can open the web interface using your browser of choice.

# ss -lnt4
State      Recv-Q Send-Q Local Address:Port               Peer Address:Port
LISTEN     0      128     127.0.0.1:9390                        *:*
LISTEN     0      128     127.0.0.1:9392                        *:*

# firefox https://127.0.0.1:9392

Despite reminding people to save the default password generated during setup, it still sometimes gets misplaced. Fortunately, the “openvasmd” utility can be used to create and remove users as well as reset their passwords.

root@kali:~# openvasmd --create-user=dookie
User created with password 'yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyy'.
root@kali:~# openvasmd --get-users
admin
dookie
root@kali:~# openvasmd --user=dookie --new-password=s3cr3t
root@kali:~# openvasmd --user=admin --new-password=sup3rs3cr3t

OpenVAS signatures can be updated with the “openvas-feed-update” utility.
