A vulnerability in cybersecurity is a weakness or flaw in a system, software, or network that can be exploited by attackers to gain unauthorized access, disrupt operations, or steal sensitive information. Vulnerabilities can arise from various sources, such as software bugs, misconfigurations, or inadequate security practices. Identifying and addressing vulnerabilities is crucial for maintaining the integrity and security of an organization's digital assets.
The CVE system provides a reference-method for publicly known information-security vulnerabilities and exposures. Each CVE entry includes an identification number, a description, and at least one public reference, making it easier for security teams to share data across separate vulnerability capabilities, such as tools, repositories, and services.
Below is an updated table listing common vulnerabilities, including their descriptions, reasons why attackers use them, severity levels, and examples of famous CVE references.
Vectra AI's platform enhances your ability to manage Common Vulnerabilities and Exposures by providing advanced threat detection and behavioral analytics. Our solution helps you identify, prioritize, and mitigate vulnerabilities efficiently. We encourage you to watch a self-guided demo of the Vectra AI platform to see how it can benefit your organization.
Vulnerabilities are flaws or weaknesses in a system's design, implementation, operation, or management that could be exploited to compromise the system's security or functionality.
A CVE is a publicly disclosed cybersecurity vulnerability, uniquely identified by a CVE ID (e.g., CVE-2021-34527). This system provides a standardized reference for security professionals worldwide, facilitating the sharing of data and collaborative efforts to address vulnerabilities.
CVEs are identified and cataloged through a collaborative process involving the MITRE Corporation, which manages the CVE Program, and various CVE Numbering Authorities (CNAs) across the globe. When new vulnerabilities are discovered, they are reported, documented, and assigned a unique CVE ID for tracking and reference purposes.
CVEs are critical for security teams because they provide a consistent and universally understood language for describing cybersecurity vulnerabilities. This standardization is essential for effective communication, threat analysis, and the implementation of appropriate security measures to mitigate vulnerabilities.
Security teams can leverage CVE information to identify known vulnerabilities within their systems, prioritize security patches and updates based on the severity and exploitability of vulnerabilities, and enhance their threat intelligence and security monitoring efforts.
Vectra AI plays a significant role in CVE management by offering advanced detection and response capabilities that can identify behaviors indicative of attempts to exploit known CVEs. By integrating CVE intelligence into its platform, Vectra AI helps security teams prioritize responses to active threats and vulnerabilities posing the most significant risk.
CVEs are prioritized for remediation based on several factors, including the severity of the vulnerability (often scored using the Common Vulnerability Scoring System, or CVSS), the ease of exploitation, the potential impact of an exploit, and the criticality of the affected system or data.
While CVEs primarily document known vulnerabilities, analyzing trends and patterns in CVE disclosures can help security teams anticipate the types of vulnerabilities that may be targeted in the future, allowing for proactive security planning and defense strengthening.
Adhering to CVE management practices can be a crucial component of compliance with various cybersecurity frameworks and regulatory requirements. Demonstrating an active approach to identifying, assessing, and mitigating known vulnerabilities is often required to meet industry standards and protect sensitive data.
Challenges include the sheer volume of CVEs being disclosed, the varying levels of detail and exploitability information provided, and the need to quickly assess and respond to vulnerabilities that may impact critical systems.
