Kepler is a vulnerability database and lookup store and API currently utilising National Vulnerability Database and NPM Advisories as data sources; implementing CPE 2.3 tree expressions and version range evaluation in realtime.
We provide a docker bundle with kepler, dedicated PostgreSQL database and Ofelia as job scheduler for continuous update
docker compose build
docker compose upWhen the application starts checks for pending database migrations and automatically applies them. Remove the --migrate option to stop when a pending migration is detected
Alternatively you can build kepler from sources. To build you need rust, cargo and libpg-dev (or equivalent PostgreSQL library for your Linux distribution)
cargo build --release
The system will automatically fetch and import new records every 3 hours if you use our bundle, while historical data must be imported manually.
Kepler currently supports two data sources, National Vulnerability Database and NPM Advisories. You can import the data sources historically as follows.
To import NIST records from all available years (2002 to 2022):
for year in $(seq 2002 2022); do
docker run -v $(pwd)/data:/data \
-e DATABASE_URL=postgres://kepler:kepler@localhost:5432/kepler \
--network=kepler_default \
kepler:dev import_nist $year -d /data;
done To import all available NPM records:
docker run -v $(pwd)/data:/data \
-e DATABASE_URL=postgres://kepler:kepler@localhost:5432/kepler\
--network=kepler_default \
kepler:dev import_npm -d /data; The system will automatically fetch and import new records records every 3 hours.
There are two primary APIs as of right now — the product API and the cve API detailed below.
Products can be listed:
curl http://localhost:8000/productsGrouped by vendor:
curl http://localhost:8000/products/by_vendorOr searched:
curl http://localhost:8000/products/search/iphoneTo use the vulnerabilities search API via cURL (prepend node- to the product name in order to search for NPM specific packages):
curl \
--header "Content-Type: application/json" \
--request POST \
--data '{"product":"libxml2","version":"2.9.10"}' \
http://localhost:8000/cve/searchResponses are cached in memory with a LRU limit of 4096 elements.
To get test and visualize the API results quickly you can use the Python utility wrappers.
pip install -r requirements-cli.txt
./kepler_cli.py linux_kernel $(uname -r)It is also possible to use the CLI to see the difference in terms of CVEs between two revisions of the same software:
diff -Naur --color <(./kepler_cli.py chrome 93.0.4577.62) <(./kepler_cli.py chrome 93.0.4577.63)JSON response for query: {"product":"libxml2","version":"2.9.10"}
