NVD-CVE-Fetcher-App

The Splunk-NVD-CVE-Fetcher-App (version 1.0.3) is a specialized integration tool designed to incorporate National Vulnerability Database (NVD) data into Splunk environments. This application bridges the gap between external vulnerability intelligence and Splunk's analytics capabilities, enabling security teams to maintain awareness of emerging threats and vulnerabilities. The app automates the entire vulnerability data lifecycle - from acquisition through normalization to analysis - eliminating manual processes that are typically time-consuming and error-prone. By leveraging the NVD's repository of Common Vulnerabilities and Exposures (CVEs), the app provides security teams with timely access to standardized vulnerability information directly within their Splunk environment. A key strength of this application is its integration with Splunk's Vulnerabilities Data Model, which transforms raw vulnerability data into a structured format optimized for security monitoring, reporting, and incident response workflows. This normalization process ensures that critical vulnerability attributes such as CVSS scores, severity ratings, affected products, and remediation information are consistently formatted and readily accessible. Compatible with Splunk Enterprise 9.0.1 and later versions, the app offers flexible configuration options including customizable polling intervals, historical data retrieval parameters, and optional API key integration to enhance data retrieval rates. The application stores all fetched vulnerability data in a dedicated index (default: "nvd_vulnerabilities"), making it easily searchable through standard Splunk queries or through the provided convenience macro. For security operations centers (SOCs) and vulnerability management teams, this application serves as an essential tool for maintaining situational awareness, prioritizing patching efforts, correlating vulnerabilities with existing assets, and enhancing overall security posture through data-driven decision-making.
