The National Vulnerability Database (NVD) is the U.S. government repository of standards-based vulnerability management data represented using the Security Content Automation Protocol (SCAP). This data enables automation of vulnerability management, security measurement, and compliance. NVD includes databases of security checklists, security related software flaws, misconfigurations, product names, and impact metrics. NVD supports the Information Security Automation Program (ISAP). NVD is managed by the U.S. government agency the National Institute of Standards and Technology (NIST).
On Friday March 8, 2013, the database was taken offline after it was discovered that the system used to run multiple government sites had been compromised by a software vulnerability of Adobe ColdFusion.[1][2]
In June 2017, threat intel firm Recorded Future revealed that the median lag between a CVE being revealed to ultimately being published to the NVD is 7 days and that 75% of vulnerabilities are published unofficially before making it to the NVD, giving attackers time to exploit the vulnerability.[3]
In addition to providing a list of Common Vulnerabilities and Exposures (CVEs), the NVD scores vulnerabilities using the Common Vulnerability Scoring System (CVSS)[4] which is based on a set of equations using metrics such as access complexity and availability of a remedy.[5]
In August 2023, the NVD initially marked an integer overflow bug in old versions of cURL as a 9.8 out of 10 critical vulnerability. cURL lead developer Daniel Stenberg responded by saying this was not a security problem, the bug had been patched nearly 4 years prior, requested the CVE be rejected, and accused NVD of "scaremongering" and "grossly inflating the severity level of issues".[6] MITRE disagreed with Stenberg and denied his request to reject the CVE, noting that "there is a valid weakness ... which can lead to a valid security impact."[7] In September 2023, the issue was rescored by the NVD as a 3.3 "low" vulnerability, stating that "it may (in theory) cause a denial of service" for attacked systems, but that this attack vector "is not especially plausible".[8]
