The CVE represents a summarized vulnerability, while the Common Vulnerability Scoring System (CVSS) assesses the vulnerability in detail and scores it, based on several factors.
The Base group represents the intrinsic qualities of a vulnerability that are constant over time and across user environments, the Temporal group reflects the characteristics of a vulnerability that change over time, and the Environmental group represents the characteristics of a vulnerability that are unique to a …
Base Metrics do not change over time – they remain the same throughout the lifetime of a vulnerability. Temporal Metrics, on the other hand, change over time as a result of activities conducted by both software vendors and hackers. Temporal metrics are sometimes, but not always, reported in the NVD.
CVSS scores are calculated using a formula consisting of vulnerability-based metrics. A CVSS score is derived from scores in these three groups: Base, Temporal and Environmental. Scores range from zero to 10, with zero representing the least severe and 10 representing the most severe.
While both standards play a critical role in secure software development, they have different purposes. In summary, CVE is a standard for identifying and naming specific vulnerabilities, while CWE is a standard for classifying and describing the types of weaknesses that can lead to vulnerabilities.
Whereas the CVE logs real-world instances of vulnerabilities and exposures in specific products, the CWE lists and defines weaknesses commonly seen in digital products. The CWE does not refer to one particular example but provides definitions for widely seen defects.
CVE stands for Common Vulnerabilities and Exposures. CVE is a glossary that classifies vulnerabilities. The glossary analyzes vulnerabilities and then uses the Common Vulnerability Scoring System (CVSS) to evaluate the threat level of a vulnerability.
The Common Configuration Scoring System (CCSS) is a set of measures of the severity of software security configuration issues. CCSS is derived from CVSS, which was developed to measure the severity of vulnerabilities due to software flaws.
CVE is a glossary that classifies vulnerabilities. The glossary analyzes vulnerabilities and then uses the Common Vulnerability Scoring System (CVSS) to evaluate the threat level of a vulnerability.
Common Weakness Enumeration (CWE) is a universal online dictionary of weaknesses that have been found in computer software. The dictionary is maintained by the MITRE Corporation and can be accessed free on a worldwide basis.
Here's the simple distinction: CWE stands for Common Weakness Enumeration, and has to do with the vulnerability—not the instance within a product or system. CVE stands for Common Vulnerabilities and Exposures, and has to do with the specific instance within a product or system—not the underlying flaw.
CVE lists common identifiers for known vulnerability information. CAPEC is a dictionary of common identifiers for attack patterns employed by adversaries to exploit weaknesses.
In other words, CVE is a list of known instances of vulnerability for specific products or systems, while CWE acts as a dictionary (so to speak) of software vulnerability types. The National Vulnerability Database (NVD) actually uses CWEs to score CVEs.
How is this different from the OWASP Top Ten The OWASP Top Ten covers more general concepts and is focused on Web applications. The CWE Top 25 covers a broader range of issues than what arises from the Web-centric view of the OWASP Top Ten, such as buffer overflows.
OWASP: The Online Web Application Security Project curates the top 10 most dangerous vulnerabilities that affect web applications today. CWE: A list of the various weaknesses affecting software systems. It relies on the CVE and OWASP lists and focuses on building a unified language around security vulnerabilities.
The Common Vulnerability Scoring System (aka CVSS Scores) provides a numerical (0-10) representation of the severity of an information security vulnerability.
CVE stands for Common Vulnerabilities and Exposures. When you see CVE, it refers to a specific instance of a vulnerability within a product or system. For example, Microsoft Outlook Elevation of Privilege Vulnerability is CVE-2023-23397. CWE stands for Common Weakness Enumeration.
