One thing mysterious is going on on the US Nationwide Institute of Requirements and Know-how (NIST) that would make many organizations susceptible to menace actors.
Since February 12, 2024, NIST has nearly utterly stopped enriching software program vulnerabilities listed in its Nationwide Vulnerability Database (NVD), the world’s most generally used software program vulnerability database.
Tom Tempo, CEO of firmware safety supplier NetRise, instructed Infosecurity that solely 200 out of the 2700 vulnerabilities, referred to as Widespread Vulnerabilities and Exposures (CVEs), printed since that date have been enriched.
Failure to complement the CVEs signifies that over 2500 vulnerabilities added to the database have been uploaded with out essential metadata data.
This data features a description of the vulnerability and software program ‘weak spot’ that would result in an exploit (referred to as Widespread Weak point and Publicity, or CWE), the names of software program merchandise impacted, the vulnerability’s criticality rating (CVSS) and the vulnerability’s patching standing.

A Vital Drop in Enrichment Knowledge Uploads on the NVD
The difficulty was first found by Josh Bressers, VP of Safety at software program safety supplier Anchore, who printed a weblog publish on March 8 displaying a major drop of enrichment information on NVD from round February 12.
Jerry Gamblin, principal engineer at Cisco Menace Detection & Response, shared one other graph displaying a major drop in CVEs below the standing ‘analyzed,’ which implies they’ve been absolutely documented and an uptick in CVEs ‘awaiting evaluation,’ in contrast with 2023.
Different posts from Gamblin and NetRise indicated comparable drops within the variety of printed CVEs enriched with essential metadata, equivalent to CWEs, Widespread Product Enumerators (CPEs) and criticality scores (CVSS).
Due to this fact, regardless of new vulnerabilities being printed they’re presently not tagged to particular merchandise, leaving organizations blind to what merchandise and techniques of their environments the particular vulnerabilities could also be impacting.
Chatting with Infosecurity, Dan Lorenc, co-founder and CEO of software program safety supplier Chainguard, commented: “It seems that the NVD has utterly given up on including CPE-matches to CVEs, that means the CVE entries don’t include any metadata round what software program is definitely affected.”
On March 13, Anchore’s Bressers shared an up to date model of the primary graph, confirming that only a few CVEs had been enriched over the previous 30 days.
A “Large Situation” For the Entire Cybersecurity Neighborhood
If such points should not resolved rapidly, they may considerably impression the safety researcher neighborhood and all organizations worldwide.
NetRise’s Tempo defined: “It signifies that you’re asking your entire cybersecurity neighborhood, in a single day, to one way or the other go determine what vulnerability is in what working system, software program package deal, software, firmware, or gadget. It’s a completely unimaginable, untenable process!”
Lorenc agreed and known as the incident a “large difficulty.”
“We are actually counting on {industry} alerts and social media to make sure we triage CVEs as rapidly as attainable,” he mentioned.
“Scanners, analyzers, and most vulnerability instruments depend on the NVD to find out what software program is affected by which vulnerabilities,” Lorenc added. “If organizations can’t triage vulnerabilities successfully it opens them as much as elevated threat and leaves a major hole of their vulnerability administration posture.”
NIST Hints at New NVD Consortium
On February 15, the Nationwide Vulnerability Database web site introduced that customers might expertise “delays in evaluation efforts” as a result of NIST “is presently working to ascertain a consortium to deal with challenges within the NVD program and develop improved instruments and strategies.”
Chris Hughes, president of Aquia, mentioned that this message didn’t present ample data for the safety neighborhood.
“What precisely is that this consortium, who will likely be concerned, what modifications will likely be made, and what kind of delays will we see as an {industry} in terms of vulnerability evaluation from probably the most extensively used vulnerability database?” Hughes wrote in a publish printed in its Resilient Cyber e-newsletter on Substack on March 11.
NetRise’s Tempo was stunned when he learn the NVD announcement. “We’ve been disclosing and enriching vulnerabilities following the identical course of for years, and fairly effectively. Why would we’d like a consortium now?”
On the time of writing, the NVD web site has not made any additional public bulletins.
Infosecurity has contacted NIST and MITRE, a US non-profit group tasked with sustaining CVEs, however they haven’t responded to a request for feedback on the time of writing.
Hypotheses Explaining the Want for an NVD Consortium
The rationale for these NVD disruptions or the necessity for a consortium stays unknown.
In response to Hughes, there have beforehand been discussions inside NVD stakeholder circles about changing CPE. Such a alternative may very well be Software program Identification (SWID) tags, a software program tagging normal supported by each the Trusted Computing Group (TCG) and the Web Engineering Job Pressure (IETF).
Nonetheless, he mentioned it’s unlikely to occur. “Given SWID has already been kicked out of the discussions round software program payments of supplies (SBOMs) as an industry-leading format, and as an alternative we see CycloneDX from OWASP and SPDX from The Linux Basis dominating the SBOM format dialogue.”
“One other helpful word is that there are people referred to as ‘the SBOM Discussion board’ presently advocating for the NVD to undertake Package deal URLs (PURLs) as effectively, given the pervasive use of software program packages and open supply software program (OSS), however whether or not that materializes remains to be to be decided,” Hughes added.

Inside discussions like these might have prompted the NVD to re-organize round a newly fashioned consortium.
Regardless of the purpose, Lorenc criticized the NVD’s lack of transparency in communication. He added that this isn’t the primary time the safety neighborhood has severely criticized the NIST-run group.
“Over the previous 12 months particularly, the NVD has acquired a lot scrutiny from {industry} and people working to repair the damaged vulnerability ecosystem. Traditionally, the NVD solved an enormous visibility hole, however at the moment, it has fallen behind,” Lorenc defined.
“In consequence, we’re beginning to see different sources pop up, in addition to nations contemplating beginning their very own. That is most obvious within the EU’s Cyber Resiliency Act,” he mentioned.
China has additionally lately up to date its vulnerability disclosure ecosystem, a current evaluation from the Atlantic Council has proven.
US Federal Authorities Issued NVD Necessities to Contractors
This episode coincides with the discharge of the most recent revision of the Federal Threat and Authorization Administration Program (FedRAMP Rev. 5), a US federal regulation requiring any firm that wishes to do enterprise with the federal authorities to make use of the NVD as a supply of reality and remediate all recognized vulnerabilities inside it.
“It seems like NIST is one way or the other making an attempt to wind this program down or hand it off whereas different areas of the federal government are forcing its adoption,” famous Lorenc.
Alongside the enrichment drop, the NVD API has additionally been experiencing points to an unprecedented scale, prompting vulnerability intelligence supplier VulnCheck to launch a free various known as VulnCheck NVD++.
Infosecurity has contacted NIST and MITRE, which haven’t responded to requests for feedback on the time of writing.
