FediVuln

A client to gather vulnerability-related information from the Fediverse. The gathered data is subsequently transmitted to the Vulnerability-Lookup API.

Installation

pipx is an easy way to install and run Python applications in isolated environments. It's easy to install.

$ pipx install FediVuln
$ export FEDIVULN_CONFIG=~/.FediVuln/conf.py

The configuration for FediVuln should be defined in a Python file (e.g., ~/.FediVuln/conf.py). You must then set an environment variable (FEDIVULN_CONFIG) with the full path to this file.

You can have a look at this example of configuration.

Usage

Register your application

$ FediVuln-Register

This script uses OAuth in order to retrieve the access token. This is achieved in several steps.

  • Register the application with Mastodon instance, a including all necessary scopes
  • Instantiate Mastodon client with client credentials
  • Log in - Generate authorization URL with the exact same scopes
  • Once the user authorizes, prompt for the authorization code
  • Use the authorization code to retrieve the access token, with the same scopes

You only have to execute it once.

Streaming

FediVuln-Stream streams data from the Fediverse and uses PyVulnerabilityLookup to create sightings in Vulnerability-Lookup.

usage: FediVuln-Stream [-h] [--user] [--public] [--push-sighting] [--push-status]

Allows access to the streaming API.

options:
  -h, --help       show this help message and exit
  --user           Streams events that are relevant to the authorized user, i.e. home timeline and notifications.
  --public         Streams public events.
  --push-sighting  Push the sightings to Vulnerability Lookup.
  --push-status    Push the status to Vulnerability Lookup.

Examples

Streams events that are relevant to the authorized user, i.e. home timeline and notifications:

$ FediVuln-Stream --user --push-sighting

If you want to get the stream of public events (local server + connected servers):

$ FediVuln-Stream --public --push-sighting

Using the --push-sighting argument, detected vulnerability IDs will be recorded in Vulnerability Lookup as sightings.

Publishing

FediVuln-Publish subscribes to an HTTP or Redis event stream and publishes the incoming data to the Fediverse.

$ FediVuln-Publish --help
usage: FediVuln-Publish [-h] [-t {vulnerability,comment,bundle,sighting}]

options:
  -h, --help            show this help message and exit
  -t, --topic {vulnerability,comment,bundle,sighting}
                        The topic to subscribe to.

The authentication to the HTTP event stream is automatically handled by PyVulnerabilityLookup.

For each incoming event, a status will be posted using the configured Mastodon account. The format of the status is dynamically tailored to the specific event topic. For instance, executing the command FediVuln-Publish -t comment will capture all new comments and share a human-readable summary on the Fediverse, including a link to the original comment on the Vulnerability-Lookup instance.

Search

usage: FediVuln-Search [-h] --query QUERY

Allows you to search for users, tags and, when enabled, full text, by default within your own posts and those you have interacted with.

options:
  -h, --help     show this help message and exit
  --query QUERY  Query of the search.
