Jake

CircleCI Python Version Support PyPI Version GitHub license GitHub issues GitHub forks GitHub stars


jake is a tool to check for your Python environments and applications that can:

  • produce CycloneDX software bill-of-materials
  • report on known vulnerabilities

jake is powered by Sonatype OSS Index and can also be used with Sonatype's Nexus IQ Server.

Installation

Install from pypi.org as you would any other Python module:

pip install jake

or

poetry add jake

Other Python package managers are available.

Usage

Getting Started

jake can guide you...

> jake --help
usage: jake [-h] [-v] [-w] [-X]  ...

Put your Python dependencies in a chokehold

optional arguments:
  -h, --help       show this help message and exit
  -v, --version    show which version of jake you are running
  -w, --warn-only  prevents exit with non-zero code when issues have been
                   detected
  -X               enable debug output

Jake sub-commands:
  
    iq             perform a scan backed by Nexus Lifecycle
    ddt            perform a scan backed by OSS Index
    sbom           generate a CycloneDX software-bill-of-materials (no
                   vulnerabilities)

jake will exit with code 0 under normal operation and 1 if vulnerabilities are found (OssIndex) or Policy Violations are detected (Nexus IQ), unless you pass the -w flag in which case jake will always exit with code 0....

Generating an SBOM

jake can take data from various inputs (or just look at your current Python environment) and produce a CycloneDX for you.

> jake sbom --help

usage: jake sbom [-h] [-i FILE_PATH] [-t TYPE] [-o PATH/TO/FILE]
                   [--output-format {json,xml}]
                   [--schema-version {1.0,1.1,1.2,1.3}]

optional arguments:
  -h, --help            show this help message and exit
  -i FILE_PATH, --input FILE_PATH
                        Where to get input data from. If a path to a file is
                        not specified directly here,then we will attempt to
                        read data from STDIN. If there is no data on STDIN, we
                        will then fall back to looking for standard files in
                        the current directory that relate to the type of input
                        indicated by the -t flag.
  -t TYPE, --type TYPE, -it TYPE, --input-type TYPE
                        how jake should find the packages from which to
                        generate your SBOM.ENV = Read from the current Python
                        Environment; CONDA = Read output from `conda list
                        --explicit`; CONDA_JSON = Read output from `conda list
                        --json`; PIP = read from a requirements.txt; PIPENV =
                        read from Pipfile.lock; POETRY = read from a
                        poetry.lock. (Default = ENV)
  -o PATH/TO/FILE, --output-file PATH/TO/FILE
                        Specify a file to output the SBOM to
  --output-format {json,xml}
                        SBOM output format (default = xml)
  --schema-version {1.0,1.1,1.2,1.3}
                        CycloneDX schema version to use (default = 1.3)

Check out these examples using STDIN:

conda list --explicit --md5 | jake sbom -t CONDA
conda list --json | jake sbom -t CONDA_JSON
cat /path/to/Pipfile.lock | python -m jake.app sbom -t PIPENV

Check out these examples specifying a manifest:

jake sbom -t PIP -i /path/to/requirements.txt
jake sbom -t PIPENV -i /path/to/Pipfile.lock

Check for vulnerabilities using OSS Index

jake will look at the packaged installed in your current Python environment and check these against OSS Index for you. Optionally, it can create a CycloneDX software bill-of-materials at the same time in a format that suits you.

> jake ddt --help

usage: jake ddt [-h] [--clear-cache] [-o PATH/TO/FILE] [--output-format {xml,json}] [--schema-version {1.2,1.1,1.0,1.3}]

optional arguments:
  -h, --help            show this help message and exit
  --clear-cache         Clears any local cached OSS Index data prior to execution
  -o PATH/TO/FILE, --output-file PATH/TO/FILE
                        Specify a file to output the SBOM to. If not specified the report will be output to the console. STDOUT is not supported.
  --output-format {xml,json}
                        SBOM output format (default = xml)
  --schema-version {1.2,1.1,1.0,1.3}
                        CycloneDX schema version to use (default = 1.3)

So you can quickly get a report by running:

> jake ddt

        │ A flaw was found in python-cryptography versions between >=1.9.0 and <2.3. The finalize_with_tag API did not enforce a minimum tag length. If a user did not validate the input length prior to passing it to finalize_with_tag an attacker could craft an invalid payload with a shortened tag (e.g. 1      │
        │ byte) such that they would have a 1 in 256 chance of passing the MAC check. GCM tag forgeries can cause key leakage.                                                                                                                                                                                         │

Check for vulnerabilities using Sonatype Nexus Lifecycle

Access Sonatype's proprietary vulnerability data using jake:

> jake iq --help

usage: jake iq [-h] -s https://localhost:8070 -i APP_ID -u USER_ID -p PASSWORD [-t STAGE]

optional arguments:
  -h, --help            show this help message and exit
  -s https://localhost:8070, --server-url https://localhost:8070
                        Full http(s):// URL to your Nexus Lifecycle server
  -i APP_ID, --application-id APP_ID
                        Public Application ID in Nexus Lifecycle
  -u USER_ID, --username USER_ID
                        Username for authentication to Nexus Lifecycle
  -p PASSWORD, --password PASSWORD
                        Password for authentication to Nexus Lifecycle
  -t STAGE, --stage STAGE
                        The stage for the report

So passing parameters that suit your Nexus Lifecycle environment you can get a report:

> jake iq -s https://my-nexus-lifecyle -i APP_ID -u USERNAME -p PASSWORD

Why Jake?

Jake The Snake was scared of Snakes. The finishing move was DDT. He finishes the Snake with DDT.

Who better to wrangle those slippery dependencies in any virtual or real environment.

Python Support

We endeavour to support all functionality for all current actively supported Python versions. However, some features may not be possible/present in older Python versions due to their lack of support.

Changelog

See our CHANGELOG.

Releasing

We perform releases manually by clicking the "On Hold" button in the CircleCI web page.

If you see a feature in the code that we have not released, please speak up, and we'll be sure to click the magic button.

We use python-semantic-release to generate releases from commits to the main branch.

For example, to perform a "patch" release, add a commit to main with a comment like below. The fix: prefix matters.

fix: Resolve vulnerability: CVE-2020-27783 in lxml

The Fine Print

Remember:

It is worth noting that this is NOT SUPPORTED by Sonatype, and is a contribution of ours to the open source community (read: you!)

  • Use this contribution at the risk tolerance that you have
  • Do NOT file Sonatype support tickets related to ossindex-lib
  • DO file issues here on GitHub, so that the community can pitch in

Phew, that was easier than I thought. Last but not least of all - have fun!
