Querying openVuln API using Date Ranges

You can now query advisories (CVRF) and OVAL definitions using a "first published" date range, as shown below:

https://api.cisco.com/security/advisories/cvrf/all/firstpublished?startDate=2017-01-01&endDate=2017-02-15

https://api.cisco.com/security/advisories/oval/all/firstpublished?startDate=2017-01-01&endDate=2017-02-15

You can also query using the advisories that were updated in a given date range, as demonstrated below:

https://api.cisco.com/security/advisories/cvrf/all/lastpublished?startDate=2017-01-01&endDate=2017-02-15 https://api.cisco.com/security/advisories/oval/all/lastpublished?startDate=2017-01-01&endDate=2017-02-15

The same concept applies when querying advisories that have a given security impact rating:

https://api.cisco.com/security/advisories/cvrf/severity/critical/lastpublished?startDate=2017-01-01&endDate=2017-02-15

https://api.cisco.com/security/advisories/cvrf/severity/high/firstpublished?startDate=2017-01-01&endDate=2017-02-15
