AuditJS

IMPORTANT NOTE: Welcome to AuditJS 4.0.0, lots has changed since 3.0.0, mainly around usage. Make sure to read the new docs.

If you have an issue migrating from AuditJS 3.x to AuditJS 4.x, please file a GitHub issue here.

Audits JavaScript projects using the OSS Index v3 REST API to identify known vulnerabilities and outdated package versions.

Supports any project with package managers that install npm dependencies into a node_modules folder including:

• npm
• Angular
• yarn
• bower

Requirements

For users wanting to use Nexus IQ Server as their data source for scanning:

1. Version 77 or above must be installed. This is when the Third-Party Scan REST API was incorporated into Nexus IQ Server.

2. The User performing the scan must have the permission "Can Evaluate Applications", this can be found in the Role Editor > User > Permissions > IQ

Installation

You can use auditjs a number of ways:

via npx (least permanent install)

npx auditjs@latest ossi

via global install (most permanent install)

npm install -g auditjs

We suggest you use it via npx, as global installs are generally frowned upon in the nodejs world.

Usage

auditjs supports node LTS versions of 8.x forward at the moment. Usage outside of these node versions will error.

Note that the OSS Index v3 API is rate limited. If you are seeing errors that indicate a problem (HTTP code 429) then you may need to make an account at OSS Index and supply the username and "token". See below for more details.

AuditJS usage with IQ Server, and what to expect

TL;DR

AuditJS should catch most if not the exact same amount of issues as the Sonatype Nexus IQ CLI Scanner. It however can't catch a few cases. If you want total visibility, please use the Sonatype Nexus IQ CLI Scanner. You can use both in tandem, too.

The full scoop

AuditJS functions by traversing your node_modules folder in your project, so it will pick up the dependencies that are physically installed. This will capture your declared as well as transititive dependencies. Once it has done this, it takes the list and converts it into something that we use to communicate with Sonatype Nexus IQ Server. The crux of this approach is that we do "coordinate" or "name based matching", which we've found to be reliable in the JavaScript ecosystem, but it will not catch corner cases such as if you've:

• Drug a vulnerable copy of jQuery into your project and left it in a folder (npm does not know about this)
• Copied and pasted code from a project into one of your files

The Nexus IQ CLI Scanner is equipped to locate and identify cases such as what I've just described. As such if you are using AuditJS, you would not be made aware of these cases, potentially until your code is audited by the IQ CLI Scanner later on.

It is our suggestion that when you are using this tooling to:

• Use AuditJS in your dev environments, etc... and use it to scan as early and as often as possible. This will alert you and other developers to using bad dependencies right off the bat.
• Use the Sonatype Nexus IQ CLI Scanner in CI/CD for a more thorough scan, and have development and your Application Security experts evaluate this scan for any "gotchas"

Usage Information

Execute from inside a node project (above the node_modules directory) to audit the dependencies. This will audit not only the direct dependencies of the project, but all transitive dependencies. To identify transitive dependencies they must all be installed for the project under audit.

If a vulnerability is found to be affecting an installed library the package header will be highlighted in red and information about the pertinent vulnerability will be printed to the screen.

By default we write all silly debug and error data to:

YOUR_HOME_DIR/.ossindex/.auditjs.combined.log

{ level: 'debug',
  message: 'Results audited',
  label: 'AuditJS',
  timestamp: '2019-12-22T20:09:33.447Z' }

Usage in CI

CircleCI

We've provided an example repo with a working CircleCI config on a "fake" but real project, you can see how it is all setup by clicking this link.

TravisCI

Proxy integration

The tool reads the http_proxy or https_proxy environment variables to perform network request through a Proxy.

Usage As A NPM Script

auditjs can be added as a devDependency to your project, and then an npm script can be added so you can leverage it in your npm scripts.

You would install auditjs like so:

$ npm i auditjs -D

An example snippet from a package.json:

  },
  "scripts": {
    "test": "mocha -r ts-node/register src/**/*.spec.ts",
    "build": "tsc -p tsconfig.json",
    "build-dev": "tsc -p tsconfig.development.json",
    "start": "node ./bin/index.js",
    "prepare": "npm run build",
    "prepublishOnly": "npm run test",
    "scan": "auditjs ossi"
  },
  "keywords": [

Now that we've added a scan script, you can run yarn run scan and your project will invoke auditjs and scan your dependencies. This can be handy for local work, or for if you want to run auditjs in CI/CD without installing it globally.

Note: these reference implementations are applicable to running an IQ scan as well. The caveat is that the config for the IQ url and auth needs to either be in the home directory of the user running the job, or stored as (preferably secret) environmental variables.

Config file

Config is now set via the command line, you can do so by running auditjs config. You will be prompted if you'd like to set Nexus IQ Server config or Sonatype OSS Index config. Reasonable defaults are provided for Sonatype Nexus IQ Server that will work for an out of the box install. It is STRONGLY suggested that you do not save your password in config (although it will work), but rather use a token from OSS Index or Nexus IQ Server.

Config passed in via the command line will be respected over filesystem based config so that you can override specific calls to either Sonatype OSS Index or Nexus IQ Server. Please see usage of either command to see how to set this command line config.

OSS Index Credentials

The OSS Index API is rate limited to prevent abuse. Guests (non-authorized users) are restricted to 16 requests of 120 packages each, which replenish at a rate of one request per minute. This means if you have 600 dependencies, then 5 requests will be used. No problem! If you have many projects which are run close to each other you could run into the limit.

You can either wait for the cool-down period to expire, or make a free account at OSS Index. By going to the "settings" page for your account, you will see your "token". Using your username (email address) and this security token you would have access to 64 requests, which is likely plenty for most use cases.

Audit.js caches results, which means if you run against multiple projects which have a common set of dependencies (and they almost certainly will) then you will not use up requests getting the same results more than once.

You can specify your credentials on either the command line or the configuration file. It is almost certainly better to put the credentials in a configuration file as described above, as using them on the command line is less secure.

Whitelisting

Whitelisting of vulnerabilities can be done! To accomplish this thus far we have implemented the ability to have a file named auditjs.json checked in to your repo ideally, so that it would be at the root where you run auditjs. Alternatively you can run auditjs with a whitelist file at a different location, with an example such as:

$ auditjs ossi --whitelist /Users/cooldeveloperperson/code/sonatype-nexus-community/auditjs/auditjs.json

The file should look like:

{
  "ignore": [{ "id": "78a61524-80c5-4371-b6d1-6b32af349043", "reason": "Insert reason here" }]
}

The only field that actually matters is id and that is the ID you receive from OSS Index for a vulnerability. You can add fields such as reason so that you later can understand why you whitelisted a vulnerability.

Any id that is whitelisted will be squelched from the results, and not cause a failure.

Alternative output formats

auditjs can output directly as json or as xml specifically formatted for JUnit test cases.

JSON:

auditjs ossi --json > file.json

XML:

auditjs ossi --xml > file.xml

We chose to allow output directly to the stdout, so that the user can decide what they want to do with it. If you'd like it to be written to a file by auditjs itself, pop in to this issue and let us know your thoughts!

Limitations

As this program depends on the OSS Index database, network access is required. Connection problems with OSS Index will result in an exception.

How to Fix Vulnerabilities

Or, "Patient: Hey Doc, it hurts when I do this. Doctor: Then don't do that."

So you've found a vulnerability. Now what? The best case is to upgrade the vulnerable component to a newer/non-vulnerable version. However, it is likely the vulnerable component is not a direct dependency, but instead is a transitive dependency (a dependency of a dependency, of a dependency, wash-rinse-repeat). In such a case, the first step is to figure out which direct dependency (and sub-dependencies) depend on the vulnerable component. The npm ls <vulnerable dependency> command will print a dependency tree that can lead you through this dependency forest.

If your project uses yarn, the yarn why <vulnerable dependency> command can provide a similar trail of breadcrumbs.

As an example, suppose we've learned that component hosted-git-info, version 2.8.8 is vulnerable (CVE-2021-23362). Use the command below to find which components depend on this vulnerable component.

  $ npm ls hosted-git-info
  [email protected] /Users/bhamail/sonatype/community/auditjs/auditjs
  └─┬ [email protected]
    └─┬ [email protected]
      └─┬ [email protected]
        └── [email protected]

Now we know the [email protected] component has a transitive dependency on the vulnerable component [email protected]. The best solution would be to upgrade read-installed to a newer version that uses a non-vulnerable version of hosted-git-info. As of this writing, however, no such version of read-installed exists. The next step is to file an issue with the read-installed project for them to update the vulnerable sub-dependencies. Be sure to read and follow any vulnerability reporting instructions published by the project: Look for a SECURITY.md file, or other instructions on how to report vulnerabilities. Some projects may prefer you not report the vulnerability publicly. Here's our bug report for this case: bug #53

To fix this particular vulnerability in our project, we need some way to force the transitive dependency to a newer version. This would be relatively easy if we were using yarn (see yarn's selective dependency resolutions). Since we are not using yarn, we will use npm-force-resolutions. See the excellent npm-force-resolutions docs for details on how this works.

After updating our package.json file as described by npm-force-resolutions,

...
  "resolutions": {
    "hosted-git-info": "^3.0.8"
  },
  "scripts": {
    "preinstall": "npx npm-force-resolutions",
...

we run npm install, and verify our transitive dependency is updated to a new version.

$ rm -rf node_modules && npm install
$ npm ls hosted-git-info
[email protected] /Users/bhamail/sonatype/community/auditjs/auditjs
└─┬ [email protected]
  └─┬ [email protected]
    └─┬ [email protected]
      └── [email protected]  invalid

npm ERR! invalid: [email protected] /Users/bhamail/sonatype/community/auditjs/auditjs/node_modules/normalize-package-data/node_modules/hosted-git-info

After updating the transitive dependency, we need to make sure the tests still pass:

npm run test
...
29 passing (84ms) 

Victory! Commit the changes, and we're done.

You could also upgrade a higher level transitive dependency: read-package-json , like so:

  "resolutions": {
    "read-package-json": "^3.0.1"
  },
