Rapid7 offers continued vulnerability coverage in the face of NVD delays

Last updated at Mon, 18 Mar 2024 19:00:07 GMT

Recently, the US National Institute of Standards and Technology (NIST) announced on the National Vulnerability Database (NVD) site that there would be delays in adding information on newly published CVEs. NVD enriches CVEs with basic details about a vulnerability like the vulnerability’s CVSS score, software products impacted by a CVE, information on the bug, patching status, etc. Since February 12th, 2024, NVD has largely stopped enriching vulnerabilities.

Given the broad usage and visibility into the NVD, the delays are sure to have a widespread impact on security operations that rely on timely and effective vulnerability information to prioritize and respond to risk introduced by software vulnerabilities.

We want to assure our customers that this does not impact Rapid7’s ability to provide coverage and checks for vulnerabilities in our products. At Rapid7, we believe in a multi-layered approach to vulnerability detection creation and risk scoring, which means that our products are not completely reliant on any single source of information, NVD included.

In fact, for vulnerability creation, we largely use vendor advisories, and as such our customers will continue to see new vulnerability detections made available without interruption. For vulnerability prioritization, our vulnerability researchers aggregate vulnerability intelligence from multiple sources, including our own research, to provide accurate information and risk scoring. Example areas of our coverage that are currently unaffected by the NVD delays include:

• Microsoft vulnerabilities - CVSS information is pulled directly from Microsoft advisory,
• Vulnerabilities with coverage that are present on the CISA KEV list, and,
• Any vulnerabilities that qualify for our Emergent Threat Response process - our researchers manually analyze and enrich these vulnerabilities as part of our ETR process

Below is an example of a latest vulnerability for Microsoft CVE-2024-26166 with the CVSS and Active Risk scores unaffected by NVD:

However, there are portions of Rapid7’s vulnerability detection database that do rely on NVD data for enrichment to populate fields such as CVSS scores. These vulnerabilities will continue to be supplemented by our proprietary risk scoring algorithm, Active Risk and will be updated as soon as enrichment information becomes available from the NVD.

Active Risk leverages intelligence from multiple threat feeds, in addition to CVSS score, like AttackerKB, Metasploit, ExploitDB, Project Heisenberg, CISA KEV list, and other third-party dark web sources to provide security teams with threat-aware vulnerability risk scores on scale of 0-1000. This approach ensures customers can continue to prioritize and remediate the most important risks despite the NVD delays.

First and foremost, we want to assure our customers that they will continue to have coverage and checks across emergent and active vulnerabilities across our products. Our teams will continue to invest in diverse vulnerability enrichment information, and we are actively working on new updates that will ensure there is no additional impact to CVSS scoring. We will continue to monitor the situation, share relevant information as it becomes available, and offer additional guidance for customers via our support channels.
