What is CVE?
CVE: CVE (Common Vulnerabilities and Exposures) is a publicly maintained catalogue of known cybersecurity vulnerabilities, each assigned a unique identifier (e.g. CVE-2024-12345) to enable consistent tracking and communication across tools and organisations.
CVE Explained in Detail
The CVE system, maintained by MITRE Corporation and funded by CISA, provides a standardised way to reference specific vulnerabilities. Each CVE entry includes a description, affected products, severity score (CVSS), and references to patches or advisories.
CVE Lifecycle
- Discovery: A vulnerability is found by a researcher, vendor, or attacker.
- Assignment: A CVE Numbering Authority (CNA) assigns a CVE ID.
- Publication: Details are published in the NVD (National Vulnerability Database).
- Remediation: Vendors release patches; organisations apply fixes based on risk priority.
CVSS Severity Ratings
- Critical (9.0–10.0): Immediate patching required.
- High (7.0–8.9): Patch within days.
- Medium (4.0–6.9): Patch within weeks.
- Low (0.1–3.9): Patch during next maintenance window.
