For a system administrator, having to perform security vulnerability analysis and software update on a daily basis can be a burden. To avoid downtime in production environment, it is common for system administrator to choose not to use the automatic update option provided by package manager and to perform update manually. This leads to the following problems.
- System administrator will have to constantly watch out for any new vulnerabilities in NVD(National Vulnerability Database) or similar databases.
- It might be impossible for the system administrator to monitor all the software if there are a large number of software installed in server.
- It is expensive to perform analysis to determine the servers affected by new vulnerabilities. The possibility of overlooking a server or two during analysis is there.
Vuls is a tool created to solve the problems listed above. It has the following characteristics.
- Informs users of the vulnerabilities that are related to the system.
- Informs users of the servers that are affected.
- Vulnerability detection is done automatically to prevent any oversight.
- Report is generated on regular basis using CRON or other methods. to manage vulnerability.
- Scan for any vulnerabilities in Linux/FreeBSD Server
- Supports Ubuntu, Debian, CentOS, Amazon Linux, RHEL, FreeBSD
- Cloud, on-premise, Docker
- Scan middleware that are not included in OS package management
- Scan middleware, programming language libraries and framework for vulnerability
- Support software registered in CPE
- Agentless architecture
- User is required to only setup one machine that is connected to other target servers via SSH
- Auto generation of configuration file template
- Auto detection of servers set using CIDR, generate configuration file template
- Email and Slack notification is possible (supports Japanese language)
- Scan result is viewable on accessory software, TUI Viewer terminal or Web UI (VulsRepo).
- Vuls doesn't update the vulnerable packages.
There are 3 ways to setup Vuls.
-
Docker container
Dockernized-Vuls with vulsrepo UI in it.
You can run install and run Vuls on your machine with only a few commands.
see https://github.com/future-architect/vuls/tree/master/setup/docker -
Manually
Hello Vuls Tutorial shows how to setup vuls manually.
This tutorial will let you scan the vulnerabilities on the localhost with Vuls.
This can be done in the following steps.
- Launch Amazon Linux
- Enable to ssh from localhost
- Install requirements
- Deploy go-cve-dictionary
- Deploy Vuls
- Configuration
- Prepare
- Scan
- TUI(Terminal-Based User Interface)
- Web UI (VulsRepo)
-
We are using the old AMI (amzn-ami-hvm-2015.09.1.x86_64-gp2 - ami-383c1956) for this example
-
Add the following to the cloud-init, to avoid auto-update at the first launch.
#cloud-config repo_upgrade: none
This is required to ssh to itself.
Create a keypair then append public key to authorized_keys
$ ssh-keygen -t rsa
$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
$ chmod 600 ~/.ssh/authorized_keysVuls doesn't support SSH password authentication. So you have to use SSH key-based authentication.
And also, SUDO with password is not supported for security reasons. So you have to define NOPASSWORD in /etc/sudoers on target servers.
Vuls requires the following packages.
- SQLite3
- git v2
- gcc
- go v1.6
$ ssh ec2-user@52.100.100.100 -i ~/.ssh/private.pem
$ sudo yum -y install sqlite git gcc

Vuls has Terminal-Based User Interface to display the scan result.
$ vuls tui
VulsRepo is a awesome Web UI for Vuls.
Check it out the Online Demo.
see https://github.com/future-architect/vuls/tree/master/setup/docker
- Fetch vulnerability information from NVD and JVN(Japanese), then insert into SQLite3.
- Scan vulnerabilities on the servers via SSH and create a list of the CVE ID
- To scan Docker containers, Vuls connect via ssh to the Docker host and then
docker execto the containers. So, no need to run sshd daemon on the containers.
- To scan Docker containers, Vuls connect via ssh to the Docker host and then
- Fetch more detailed information of the detected CVE from go-cve-dictionary
- Send a report by Slack and Email
- Write scan results to JSON file to show the latest report on your terminal
-
On Ubuntu and Debian
Vuls issuesapt-get changelogfor each upgradable packages and parse the changelog.
apt-get changelogis slow and resource usage is heavy when there are many updatable packages on target server.
Vuls stores these changelogs to KVS(boltdb).
From the second time on, the scan speed is fast by using the local cache. -
On CentOS
Vuls issuesyum update --changelogto get changelogs of upgradable packages at once and parse the changelog.
Scan speed is fast and resource usage is light. -
On Amazon, RHEL and FreeBSD
High speed scan and resource usage is light because Vuls can get CVE IDs by using package manager(no need to parse a changelog).

Vuls supports two types of SSH. One is native go implementation. The other is external SSH command. For details, see -ssh-external option
Multiple SSH authentication methods are supported.
- SSH agent
- SSH public key authentication (with password and empty password) Password authentication is not supported.
Configtest subcommand check if vuls is able to connect via ssh to servers/containers defined in the config.toml.

Configuration
To detect the vulnerbility of Ruby on Rails v4.2.1, cpeNames needs to be set in the servers section.[servers] [servers.172-31-4-82] host = "172.31.4.82" user = "ec2-user" keyPath = "/home/username/.ssh/id_rsa" cpeNames = [ "cpe:/a:rubyonrails:ruby_on_rails:4.2.1", ]
It is common that keep Docker containers runnning without SSHd daemon.
see Docker Blog:Why you don't need to run SSHd in your Docker containers
Vuls scans Docker containers via docker exec instead of SSH.
For more details, see Architecture section
-
To scan all of running containers
"${running}"needs to be set in the containers item.[servers] [servers.172-31-4-82] host = "172.31.4.82" user = "ec2-user" keyPath = "/home/username/.ssh/id_rsa" containers = ["${running}"] -
To scan specific containers
The container ID or container name needs to be set in the containers item.
In the following example, onlycontainer_name_aand4aa37a8b63b9will be scanned.
Be sure to check these containers are running state before scanning.
If specified containers are not running, Vuls gives up scanning with printing error message.[servers] [servers.172-31-4-82] host = "172.31.4.82" user = "ec2-user" keyPath = "/home/username/.ssh/id_rsa" containers = ["container_name_a", "4aa37a8b63b9"] -
