CVE, CWE and NVD
CVE, CWE and NVD are three important concepts in cybersecurity. They are all related to software vulnerabilities, but they serve different purposes.
NVD ( https://nvd.nist.gov/ )
The NVD was first published in 2005 by the National Institute of Standards and Technology (NIST). It was created to provide a centralized repository of vulnerability management data. The NVD is now maintained by NIST. NVD is a U.S. government repository of vulnerability management data. The NVD includes data from CVE, CWE, and other sources. It also provides additional information such as CVSS scores, references to exploit code, and remediation guidance.
Purpose: NVD is used by security professionals to assess and manage the risks of software vulnerabilities. It is also used by software vendors to provide patches and updates for vulnerable products.
CWE ( https://cwe.mitre.org/ )
The CWE was first published in 2002 by MITRE. It was created to provide a common language for discussing and classifying software weaknesses. The CWE is now maintained by the MITRE CWE Team. CWE is a dictionary of common software weaknesses. CWE weaknesses are the underlying causes of security vulnerabilities. Each CWE entry includes a unique CWE identifier, a definition of the weakness, and a list of common mitigations.
Purpose: CWE is used by security professionals to understand, prevent, and mitigate software vulnerabilities. It is also used by software developers to write more secure code.
CVE ( https://cve.mitre.org/ )
The CVE List was first published in 1999 by MITRE. It was created to provide a common language for discussing and tracking software vulnerabilities. The CVE List is now maintained by the MITRE CVE Numbering Authority (CNA). CVE is a dictionary of publicly known security vulnerabilities and exposures. Each CVE record includes a unique CVE identifier, a description of the vulnerability, and a list of affected products or software versions.
Purpose: CVE is used by security professionals to identify, track, and manage software vulnerabilities. It is also used by software vendors to provide patches and updates for vulnerable products.
NVD, CWE and CVE are all related to software vulnerabilities, but they serve different purposes. CVE is a dictionary of known vulnerabilities, CWE is a dictionary of common weaknesses, and NVD is a repository of vulnerability management data.
NVD uses CWE to categorise and score CVE vulnerabilities. This allows NVD to provide more detailed information about each vulnerability, such as its potential impact and how to mitigate it.
Generally NVD, CWE and CVE can be used together:
The NVD entry for CVE-2023–23397 provides additional information such as a CVSS score of 9.8 (critical), references to exploit code, and remediation guidance.
The CWE weakness associated with CVE-2023–23397 is CWE-117: Improper Output Neutralization.
CVE-2023–23397 is a vulnerability in Microsoft Outlook that could allow an attacker to gain elevated privileges.
By understanding NVD, CWE and CVE, security professionals can better understand and manage software vulnerabilities.
~CVE is a dictionary of known vulnerabilities, CWE is a dictionary of common weaknesses, and NVD is a repository of vulnerability management data.
Security professionals can use NVD, CWE and CVE to identify, track, understand, prevent, mitigate, and manage software vulnerabilities.
