Abstract

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.

Vuls-Motivation

  • 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).

What Vuls Doesn't Do

  • Vuls doesn't update the vulnerable packages.

Setup Vuls

There are 3 ways to setup Vuls.


Tutorial: Hello Vuls

This tutorial will let you scan the vulnerabilities on the localhost with Vuls.
This can be done in the following steps.

  1. Launch Amazon Linux
  2. Enable to ssh from localhost
  3. Install requirements
  4. Deploy go-cve-dictionary
  5. Deploy Vuls
  6. Configuration
  7. Prepare
  8. Scan
  9. TUI(Terminal-Based User Interface)
  10. Web UI (VulsRepo)

Step1. Launch Amazon Linux

Step2. SSH setting

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_keys

Vuls 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.

Step3. Install requirements

Vuls requires the following packages.

$ ssh ec2-user@52.100.100.100  -i ~/.ssh/private.pem
$ sudo yum -y install sqlite git gcc
$ wget https://storage.googleapis.com/golang/go1.6.linux-amd64.tar.gz
$ sudo tar -C /usr/local -xzf go1.6.linux-amd64.tar.gz
$ mkdir $HOME/go

Add these lines into /etc/profile.d/goenv.sh

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

Set the OS environment variable to current shell

$ source /etc/profile.d/goenv.sh

Step4. Deploy go-cve-dictionary

go get

$ sudo mkdir /var/log/vuls
$ sudo chown ec2-user /var/log/vuls
$ sudo chmod 700 /var/log/vuls
$ go get github.com/kotakanbe/go-cve-dictionary

If an error occurred while go get, check the following points.

Fetch vulnerability data from NVD.
It takes about 10 minutes (on AWS).

$ for i in {2002..2016}; do go-cve-dictionary fetchnvd -years $i; done
... snip ...
$ ls -alh cve.sqlite3
-rw-r--r-- 1 ec2-user ec2-user 7.0M Mar 24 13:20 cve.sqlite3

Step5. Deploy Vuls

Launch a new terminal and SSH to the ec2 instance.

go get

$ go get github.com/future-architect/vuls

If an error occurred while go get, check the following points.

Step6. Config

Create a config file(TOML format).
Then check the config.

$ cat config.toml
[servers]

[servers.172-31-4-82]
host         = "172.31.4.82"
port        = "22"
user        = "ec2-user"
keyPath     = "/home/ec2-user/.ssh/id_rsa"

$ vuls configtest

Step7. Setting up target servers for Vuls

$ vuls prepare

see Usage: Prepare

Step8. Start Scanning

$ vuls scan -cve-dictionary-dbpath=$PWD/cve.sqlite3
INFO[0000] Start scanning (config: /home/ec2-user/config.toml)
INFO[0000] Start scanning
INFO[0000] config: /home/ec2-user/config.toml
INFO[0000] cve-dictionary: /home/ec2-user/cve.sqlite3

Architecture

Vuls-Architecture

go-cve-dictinary

  • Fetch vulnerability information from NVD and JVN(Japanese), then insert into SQLite3.

Vuls

  • 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 exec to the containers. So, no need to run sshd daemon on the containers.
  • Fetch more detailed information of the detected CVE from go-cve-dictionary
  • Insert scan result into SQLite3
  • Send a report by Slack and Email
  • Show the latest report on your terminal

Vuls-Scan-Flow


Performance Considerations

  • On Ubuntu and Debian
    Vuls issues apt-get changelog for each upgradable packages and parse the changelog.
    apt-get changelog is 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 issues yum update --changelog to 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).

Distribution Scan Speed
Ubuntu First time: Slow / From the second time: Fast
Debian First time: Slow / From the second time: Fast
CentOS Fast
Amazon Fast
RHEL Fast
FreeBSD Fast

    #channel      = "${servername}"
    iconEmoji    = ":ghost:"
    authUser     = "username"
    notifyUsers  = ["@username"]
    
    • hookURL : Incomming webhook's URL

    • channel : channel name.
      If you set ${servername} to channel, the report will be sent to each channel.
      In the following example, the report will be sent to the #server1 and #server2.
      Be sure to create these channels before scanning.

      [slack]
      channel      = "${servername}"

    You can overwrite the default value specified in default section.

    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.

Usage: Configtest

Configtest subcommand check if vuls is able to connect via ssh to servers/containers defined in the config.toml.

$ vuls configtest --help
configtest:
        configtest
                        [-config=/path/to/config.toml]
                        [-ask-key-password]
                        [-ssh-external]

Vuls supports different types of SSH.

By Defaut, using a native Go implementation from crypto/ssh.
This is useful in situations where you may not have access to traditional UNIX tools.

To use external ssh command, specify this option.
This is useful If you want to use ProxyCommand or chiper algorithm of SSH that is not supported by native go implementation.
Don't forget to add below line to /etc/sudoers on the target servers. (username: vuls)

Defaults:vuls !requiretty

-ask-key-password option

SSH key password -ask-key-password
empty password -
with password required or use ssh-agent

-report-json , -report-text option

At the end of the scan, scan results will be available in the $PWD/result/current/ directory.
all.(json|txt) includes the scan results of all servres and servername.(json|txt) includes the scan result of the server.

Example: Scan all servers defined in config file

$ vuls scan \
      --report-slack \ 
      --report-mail \
      --cvss-over=7 \
      -ask-key-password \
      -cve-dictionary-dbpath=$PWD/cve.sqlite3

With this sample command, it will ..

  • Ask SSH key passsword before scanning
  • Scan all servers defined in config file
  • Send scan results to slack and email
  • Only Report CVEs that CVSS score is over 7
  • Print scan result to terminal

Example: Scan specific servers

$ vuls scan \
      -cve-dictionary-dbpath=$PWD/cve.sqlite3 \ 
      server1 server2

With this sample command, it will ..

  • Use SSH Key-Based authentication with empty password (without -ask-key-password option)
  • Scan only 2 servers (server1, server2)
  • Print scan result to terminal

Example: Put results in S3 bucket

To put results in S3 bucket, configure following settings in AWS before scanning.

$ vuls scan \
      -cve-dictionary-dbpath=$PWD/cve.sqlite3 \ 
      -report-s3 \
      -aws-region=ap-northeast-1 \
      -aws-s3-bucket=vuls \
      -aws-profile=default 

With this sample command, it will ..

  • Use SSH Key-Based authentication with empty password (without -ask-key-password option)
  • Scan all servers defined in config file
  • Put scan result(JSON) in S3 bucket. The bucket name is "vuls" in ap-northeast-1 and profile is "default"

Example: Put results in Azure Blob storage

To put results in Azure Blob Storage, configure following settings in Azure before scanning.

  • Create a container
$ vuls scan \
      -cve-dictionary-dbpath=$PWD/cve.sqlite3 \ 
      -report-azure-blob \
      -azure-container=vuls \
      -azure-account=test \
      -azure-key=access-key-string 

With this sample command, it will ..

  • Use SSH Key-Based authentication with empty password (without -ask-key-password option)
  • Scan all servers defined in config file
  • Put scan result(JSON) in Azure Blob Storage. The container name is "vuls", storage account is "test" and accesskey is "access-key-string"

account and access key can be defined in environment variables.

$ export AZURE_STORAGE_ACCOUNT=test
$ export AZURE_STORAGE_ACCESS_KEY=access-key-string
$ vuls scan \
      -cve-dictionary-dbpath=$PWD/cve.sqlite3 \ 
      -report-azure-blob \
      -azure-container=vuls

Example: Add optional key-value pairs to JSON

Optional key-value can be outputted to JSON.
The key-value in the default section will be overwritten by servers section's key-value.
For instance, you can use this field for Azure ResourceGroup name, Azure VM Name and so on.

Usage: Scan vulnerability of non-OS package

It is possible to detect vulnerabilities in non-OS packages, such as something you compiled by yourself, language libraries and frameworks, that have been registered in the CPE.

  • How to search CPE name by software name

  • 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",
    ]
    

Usage: Scan Docker containers

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, only container_name_a and 4aa37a8b63b9 will 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"]
    

Usage: TUI

Display the latest scan results

$ vuls tui -h
tui:
	tui [-results-dir=/path/to/results]

  -results-dir string
        /path/to/results (default "$PWD/results")
  -debug-sql
    	debug SQL

Key binding is bellow.

Usage: go-cve-dictionary on different server

Run go-cve-dictionary as server mode before scanning on 192.168.10.1

$ go-cve-dictionary server -bind=192.168.10.1 -port=1323

Run Vuls with -cve-dictionary-url option.

$ vuls scan -cve-dictionary-url=http://192.168.0.1:1323

Usage: Update NVD Data

$ go-cve-dictionary fetchnvd -h
fetchnvd:
        fetchnvd
                [-last2y]
                [-dbpath=/path/to/cve.sqlite3]
                [-debug]
                [-debug-sql]

  -dbpath string
        /path/to/sqlite3 (default "$PWD/cve.sqlite3")
  -debug
        debug mode
  -debug-sql
        SQL debug mode
  -last2y
        Refresh NVD data in the last two years.
  • Fetch data of the entire period
$ go-cve-dictionary fetchnvd -entire
  • Fetch data in the last 2 years
$ go-cve-dictionary fetchnvd -last2y
