VulnDB Data Mirror

A simple Java command-line utility to mirror the entire contents of the VulnDB service from Risk Based Security.

The intended purpose of vulndb-data-mirror is to be able to replicate the VulnDB vulnerabiity data inside a company firewall so that local (faster) access to data can be achieved.

In addition to mirroring functionality, VulnDB Data Mirror includes a parser that can automatically convert JSON data to model objects (defined as POJO's). This greatly eases the ramp-up time needed to consume the VulnDB data in a programmatic way.

The VulnDB service utilizes a paginated REST API that must be walked for each type of feed. Due to the large data-set the service provides, it may take an hour or more to mirror the contents.

For best results, use vulndb-data-mirror with cron or another scheduler to keep the mirrored data fresh.

A subscription to VulnDB is required for use. Contact VulnDB for evaluation and subscription information. VulnDB Data Mirror or it's creator are not affiliated with VulnDB or Risk Based Security. This is a community-driven project that acknowledges the value of third-party vulnerability intelligence to enhance or supplement publicly disclosed information.

By using VulnDB Data Mirror, you accept that it will be used in a manner that conforms to the VulnDB terms of service.


VulnDB Data Mirror is distributed two different ways.

Pre-compiled binaries are available. This distribution is intended to be extracted and executed in order to run and maintain a working VulnDB mirror. This is the recommended method for most users.

The standalone library is available in the Maven Central Repository. This distribution is useful for programmatic access to the mirroring or parsing functionality.




vulndb-data-mirror.bat --consumer-key mykey --consumer-secret mysecret --dir "c:\path\to\mirror"

Unix/Linux --consumer-key mykey --consumer-secret mysecret --dir "/path/to/mirror"

When running, the console output will resemble:

VulnDB API Status:
Organization Name.............: Example Inc.
Name of User Requesting.......: Jane Doe
Email of User Requesting......:
Subscription Expiration Date..: 2018-12-31
API Calls Allowed per Month...: 25000

Mirror Recovery

VulnDB Data Mirror can recover from several types of errors. Upon a successful request to VulnDB, this utility will store a timestamp and the last successful page number processed. Pagination of VulnDB defaults to retrieving 100 records at a time. In the event of a network or service error, it is possible to start again where the mirroring left off.

This information is stored in located in the specified mirror directory.

VulnDB API License

The process of mirroring the contents of VulnDB takes several thousand requests. You may estimate the number of requests required by dividing 100 by the total number of results in each of the three feeds. After mirroring is complete, make a backup of the contents so that a full mirror does not have to take place again. VulnDB may be licensed based on the number of API calls made to the service. Check with the vendor for details.
