Support with `hasCertAlerts` and `hasCertNotes ` with the NVD API

Frameworks, Standards, and Tools
1

I was reading your very informative post about the NVD API, specifically about CVEs:

In the post you refer to these filters

  • hasCertAlerts: if set, only returns the CVE that contain a Technical Alert from US-CERT
  • hasCertNotes: if set, only returns the CVE that contain a Vulnerability Note from CERT/CC

However, I can’t seem to get these to return any data.

Here is an example of my request for hasCertNotes:

curl --location 'https://services.nvd.nist.gov/rest/json/cves/2.0?hasCertNotes=true' \
--header 'apiKey: HIDDEN'

But the response is empty.

Can someone give me any pointers?

Hey @0101001001001 ,

You’re soooooo close :slight_smile:

The hasCertNotes and hasCertAlerts properties are not boolean. You just need to pass them with a null value to get a response.

e.g.

curl --location 'https://services.nvd.nist.gov/rest/json/cves/2.0?hasCertAlerts=&lastModStartDate=2024-01-01T00%3A00%3A00.000&lastModEndDate=2024-01-31T23%3A59%3A59.000' \
--header 'apiKey: REDACTED'

You know they’re related to CertAlerts or CertAlerts (if not using these filters) b/c the references.tags property of the CVE will contain US Government Resource

e.g.

"tags": [
                            "Broken Link",
                            "Third Party Advisory",
                            "US Government Resource"
                        ]
