CVE-1999-0631 in Host
Summary
by MITRE
** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: None. Reason: this candidate is solely about a configuration that does not directly introduce security vulnerabilities, so it is more appropriate to cover under the Common Configuration Enumeration (CCE). Notes: the former description is: "The NFS service is running."
Be aware that VulDB is the high quality source for vulnerability data.

This CVE entry represents a classification that was ultimately rejected by the MITRE Corporation and should not be used for vulnerability assessment or security research purposes. The candidate number was withdrawn because it addressed a configuration state rather than an actual security vulnerability. The original description referenced merely the presence of an NFS service running on a system, which by itself does not constitute a security flaw. This type of entry falls outside the scope of what CVE aims to catalog, which focuses on actual vulnerabilities that can be exploited to compromise system security. The rejection highlights the distinction between system configurations and genuine security weaknesses that require remediation.
The fundamental issue with this CVE candidate lies in its misunderstanding of what constitutes a vulnerability versus a system state. Simply having an NFS service running represents a normal operational configuration rather than a security flaw. Many system services operate in a running state without introducing security risks, and the mere presence of a service does not automatically create exploitable conditions. This misclassification demonstrates the importance of proper vulnerability categorization and the need to distinguish between operational states and actual security weaknesses that can be leveraged by attackers.
From a cybersecurity perspective, this rejected CVE illustrates the critical importance of proper vulnerability identification and classification processes. The Common Configuration Enumeration (CCE) system was identified as more appropriate for cataloging this type of configuration state, which emphasizes the need for specialized taxonomies to address different aspects of system security. The distinction between configurations that require monitoring and those that represent actual security vulnerabilities is fundamental to effective risk management and security posture assessment. This example underscores how misclassification can lead to confusion in vulnerability management and security response activities.
The rejection of this CVE candidate also reflects broader industry standards and best practices for vulnerability management. According to CWE guidelines, configuration issues that do not directly introduce security vulnerabilities should be addressed through configuration management frameworks rather than vulnerability databases. The ATT&CK framework would not categorize a running NFS service as a technique or tactic, as it represents a system state rather than an active security threat. This classification decision aligns with industry practices that focus CVE entries on exploitable weaknesses rather than operational configurations that may or may not be appropriate for a given security context.
Organizations should understand that the presence of services like NFS requires proper configuration management and security hardening rather than vulnerability remediation. While NFS services can introduce security risks when improperly configured, simply running the service without proper access controls, authentication mechanisms, and network segmentation does not automatically create a vulnerability. The proper approach involves implementing security controls such as access control lists, network firewalls, and proper authentication protocols rather than treating the mere existence of the service as a vulnerability requiring patching or remediation. This distinction is crucial for effective security resource allocation and risk prioritization.
