Navi Pro - The Tenable.io Swiss Army Knife

A command-line tool which leverages the Tenable.io API to reduce the time it takes to get information that is common in Cyber Exposure or Vulnerability Management.

*** This is not Supported by Tenable ***

Important Notes

Navi Pro will download the entire data-set(90 days) locally after API keys are entered and the update command is used! To download Vuln and Asset data you have to be an Administrator in Tenable.io.

All Vulns and All Assets are downloaded into a SQLLITE database named navi.db in the current directory.

Most of the API calls nessessary to make navi work require access to your all of the available data. Tenable.io has a 5000 record limit so Navi Pro utilizes the Export API.

The data will not be updated until you run the update command. Keep this in mind when adding elements to Tenable.io like Tags.

navi update

Alternatively you can select which export you want to update:

navi update -assets

navi update -vulns

Furthermore, you can limit how much data is downloaded by using the --days command

navi update -assets --days 2

You can even specify your export id.

navi update -vulns --exid 123456-987654-asdfgh-jklopi-ididis

My container keeps getting "Killed"

To speed up downloads navi uses threading. It pulls 500 asset chunks on 10 threads and since the vulnerabilities per asset fluctuate this can spike the memory above 2G. If this happens increase your memeory to 4G.

Directions for Windows

What is the biggest Tenable.io instance Navi has been tested on?

Navi 5.1.4 was recently tested on a container with 100,000 assets and 13 million vulnerabilties.
It took 30 mins for t.io to prepare the download and 30 mins to download and parse the data into navi.db. On another internet connection the entire process too 2.5 hours.

Download and Configure navi in a Docker Container

docker pull silentninja/navi:latest

docker run -it -p 8000:8000 silentninja/navi:latest /bin/bash 

navi keys

navi update

Detach from Container

CTR+Q+P - CTR+Q+P

Attach to Contianer

docker attach <container id>

<press enter>

Configure For Reporting

Navi has a few reporting capabilities where a CSV is the output. To extract this data from the container you will need to launch the container with port 8000 exposed and use the 'http' command to extract the reports.

docker run -it -p 8000:8000 silentninja/navi:latest /bin/bash

Extract Data

To extract data from the container you need to run an http server. Use the below built in command.

navi http

• Navigate to the website: http://0.0.0.0:8000
• Simply download the item you want by clicking on it.

Download and Configure Navi using Python3 Setup file

Prepare your Machine

• Install Python3
• Install Setuptools
• Install Git

Clone the Repo

Create a new Directory

mkdir tenable

Change into your new directory

cd tenable

Clone the repo

git clone https://github.com/packetchaos/Navi.git

Usage

Before you begin you need the Keys! The program will continue to error out without valid API keys

navi keys

Add assets manually or via a CSV file - 'add'

To add an asset you need an IP address; Everything else is optional. If you are going to use a CSV file you need to structure it in this order: IP, Mac, Hostname, FQDN. This is the order the information is parsed so getting it incorrect will cause errors.

• --ip TEXT IP address(s) of new asset
• --mac TEXT Mac Address of new asset
• --netbios TEXT NetBios of new asset
• --fqdn TEXT FQDN of new asset
• --hostname TEXT Hostname of new asset
• --list - TEXT Import all assets in the CSV file

• --output TEXT Create a Tag based on the text in the output. Requires --plugin

Examples

navi tag --c "My Category" --v "My Value" --d "My description" --plugin 93561
navi tag --c "Application Vulns" --v "Java vulns" --name java
navi tag --c "Agent Group" --v "Linux Agents" --group "Linux"

Note on Tagging assets

If you created a new Tag you will need to run an update on the assets to download the new Tag relationships. This is especially important if you want to export using your newly created tag.

navi update -assets

Create Access Groups by Tags or Agent Groups - 'agroup'

• --name TEXT Create an Access group with the following Name
• -tag Create a Access Group by a Tag
• --c TEXT Category name to use
• --v TEXT Tag Value to use; requires --c and Category Name
• --group TEXT Create a Tag based on a Agent Group

Examples

navi agroup --name "My New Group" -tag --c "OS" --v "Linux"

navi agroup --name "My Other Group" --group "Linux

Bulk Adjust ACRs based on a Tag - 'lumin'

• --acr --> The new ACR value (1-10)
• --c --> The Tag Category to use
• --v --> The Tag value to use
• --note --> Justification for ACR change

Note - ACR Exceptions?

Tag your assets with "NO:UPDATE" if you don't want to be affected by bulk ACR changes
Category = NO
Value = UPDATE

Examples

navi lumin --acr 10 --c "Applications" --v "Core Business" --note "Main application"

Export Asset, Agent, Consec, or Webapp Data - 'export'

• -consec --> Export Container Security summary info into a CSV.
• -licensed --> Export a List of all Licensed Assets into a CSV.
• -lumin --> Export all Asset data including ACR and AES into a CSV. This will take some time
• --network --> Export all Assets of a given network
• -bytag Export all assets by tag; Include ACR and AES into a CSV
• --c TEXT Export bytag with the following Category name
• --v TEXT Export bytag with the Tag Value; requires --c and Category Name
• --ec TEXT Exclude tag from export with Tag Category; requires --ev
• --ev TEXT Exclude tag from export with Tag Value; requires --ec

Examples

navi export -assets

navi export -agents -assets -webapp -consec -licensed

navi export --network 00000000-0000-0000-0000-000000000000

Export into a CSV, but include the ACR and AES of each asset. This takes a bit of time.

navi export -lumin

Export into a CSV via a Tag

navi export -bytag --c "OS" --v "Linux"

Export into a CSV via a Tag; but exclude a specific Tag.

navi export -bytag --c "OS" --v "Linux" --ec "OS" --ev "AWS"

Create 100s of Webapp Scans from a CSV File

To Receive a file for Navi Pro to use you must push the file to the container. Netcat is installed on the container to do this, or you can use the 'listen' command to accomplish this.

navi spider <your_csv_file.csv>

• Choose your Scan type : Webapp Overview or Webapp Scan
• Choose your scanner: A list will be displayed
• Scans will be created but not started.
• An output of the Webapp URL and Scan ID will be displayed on completion

Getting Data into the Container

From the container - Prepare your container to receive a file

navi listen

or

nc -l -p 8000 > yourfilename.csv

From the computer with the file - Send the file

nc containerhostIP 8000 < yourfilename.csv
