The Growing Crisis in CVE Data Quality

In cybersecurity, the Common Vulnerabilities and Exposures (CVE) system serves as a critical pillar by providing a standardized method for identifying and cataloging vulnerabilities. However, this foundational system is now facing a burgeoning crisis in data quality, which threatens the efficacy of global cybersecurity efforts. This talk delves into the heart of the issue, exploring how the exponential growth in CVE assignments, coupled with the National Vulnerability Database's (NVD) slowdown in processing and analysis, has led to a significant degradation in CVE data quality. We'll begin by examining the root causes of this crisis, including the overwhelming increase in vulnerability disclosures and the inclusion of less critical issues by new CVE Numbering Authorities (CNAs. The discussion will then pivot to the implications of this decline in data quality. With inaccurate, outdated, or cluttered CVE entries, security teams struggle to discern actionable intelligence from noise. This not only hampers effective vulnerability management but also misguides prioritization, potentially leaving organizations exposed to exploits. The talk will also propose potential solutions and reforms necessary to restore the integrity and utility of the CVE system. This includes advocating for stricter criteria for CVE assignments, enhancing the automation of vulnerability assessments, and fostering better collaboration between CNAs, the CVE program, and cybersecurity communities.
