Vendors can then report the vulnerability to a CNA along with patch information, if available. These programs are set up by vendors and provide a reward to users who report vulnerabilities directly to the vendor, as opposed to making the information public. Many vulnerabilities are also discovered as part of bug bounty programs. Vulnerability information is provided to CNAs via researchers, vendors, or users. CNAs are granted their authority by MITRE, which can also assign CVE numbers directly. ![]() ![]() These organizations include research organizations, and security and IT vendors. There are currently 114 organizations, across 22 countries, that are certified as CNAs. A CVE identifier follows the format of - CVE. When vulnerabilities are verified, a CVE Numbering Authority (CNA) assigns a number. Severity of top CVE vulnerabilities CVE Identifiers The exception is if there is no way to use the shared component without including the vulnerability. If vulnerabilities stem from shared protocols, standards, or libraries a separate CVE is assigned for each vendor affected. The vulnerability is submitted with evidence of security impact that violates the security policies of the vendor.Įach product vulnerability gets a separate CVE. The vulnerability is known by the vendor and is acknowledged to cause a security risk. You must be able to fix the vulnerability independently of other issues. These criteria includes: Independent of other issues To be categorized as a CVE vulnerability, vulnerabilities must meet a certain set of criteria. Security advisories, vulnerability databases, and bug trackers all employ this standard. CVE identifiers serve to standardize vulnerability information and unify communication amongst security professionals. The CVE glossary was created as a baseline of communication and source of dialogue for the security and tech industries. All vulnerability and analysis information is then listed in NIST’s National Vulnerability Database (NVD). After listing, vulnerabilities are analyzed by the National Institute of Standards and Technology (NIST). Once evaluated and identified, vulnerabilities are listed in the publicly available MITRE glossary. SCAP evaluates vulnerability information and assigns each vulnerability a unique identifier. Vulnerabilities are collected and cataloged using the Security Content Automation Protocol (SCAP). It is maintained by the MITRE Corporation with funding from the US Division of Homeland Security. The CVE glossary is a project dedicated to tracking and cataloging vulnerabilities in consumer software and hardware. A CVE score is often used for prioritizing the security of vulnerabilities. The glossary analyzes vulnerabilities and then uses the Common Vulnerability Scoring System (CVSS) to evaluate the threat level of a vulnerability. ![]() CVE is a glossary that classifies vulnerabilities. What is the Common Vulnerabilities and Exposures (CVE) GlossaryĬVE stands for Common Vulnerabilities and Exposures.
