What is CVSS (Common Vulnerability Scoring System)?

The Common Vulnerability Scoring System (CVSS) is a standard that can be used to uniformly assess the vulnerability of computer systems using a point system from 0 to 10. CVSS is currently available in version 3.1 and recognizes the vulnerability classifications “none”, “low”, “medium”, “high” and “critical”.

In cybersecurity, it is crucial to assess the severity and potential impact of vulnerabilities to prioritize remediation efforts effectively. This is where the Common Vulnerability Scoring System (CVSS) comes into play. CVSS is a widely adopted industry standard that provides a consistent method for rating vulnerabilities.

In this article, we will delve into the details of CVSS, its components, and how it aids in vulnerability management.

What is CVSS?

CVSS stands for Common Vulnerability Scoring System. It is a standardized framework used to assess and measure the severity of vulnerabilities in computer systems and software. CVSS provides a consistent and objective way to rate vulnerabilities, allowing organizations to prioritize their remediation efforts based on the severity of the vulnerabilities.

CVSS assigns a numerical score to each vulnerability based on various metrics, such as the impact of the vulnerability on the confidentiality, integrity, and availability of the affected system, as well as the complexity and exploitability of the vulnerability. The scoring system provides a common language for security professionals to communicate the severity of vulnerabilities and make informed decisions about mitigating risks.

CVSS aims to provide a standardized and universal method for assessing vulnerabilities across different systems and platforms. It enables organizations to prioritize their resources and focus on first addressing the most critical vulnerabilities. By using a consistent scoring system, security teams can better understand the potential impact of a vulnerability and make informed decisions regarding risk management and remediation efforts.

The importance of vulnerability scoring, as provided by CVSS, lies in its ability to help organizations effectively prioritize their response to vulnerabilities. With the vast number of vulnerabilities discovered daily, it is crucial to have a systematic approach to identify and address the most severe vulnerabilities that pose the greatest risk to the organization’s security. CVSS allows organizations to assess and compare vulnerabilities in a standardized manner, enabling them to allocate their resources efficiently and effectively.

By using CVSS scores, security professionals can determine the severity of a vulnerability and allocate appropriate resources to patch or mitigate the vulnerability. This helps organizations optimize their security efforts, reduce the potential impact of vulnerabilities, and improve overall security posture. Additionally, vulnerability scoring can aid in communicating the severity of vulnerabilities to stakeholders, such as management, customers, and other security teams, facilitating a common understanding of the risks involved.

CVSS plays a crucial role in vulnerability management and risk assessment by providing a standardized and objective method to score and prioritize vulnerabilities. It enhances the efficiency and effectiveness of security operations, allowing organizations to proactively address their most critical security weaknesses.

The Components of CVSS

The CVSS (Common Vulnerability Scoring System) consists of three main metric groups: Base Metrics, Temporal Metrics, and Environmental Metrics.

  What is a Certificate Authority (CA)?

Base Metrics

  • Attack Vector: This metric represents how the vulnerability can be exploited. It assesses whether the vulnerability can be exploited locally (such as physical access to the system) or remotely (such as through a network). The possible values are “Network” (remotely exploitable), “Adjacent Network” (requires access to the adjacent network), “Local” (requires local system access), and “Physical” (requires physical access to the system).
  • Attack Complexity: This metric measures the effort and skills required to exploit the vulnerability. It considers factors like the level of expertise needed and the availability of tools or resources. The possible values are “Low” (simple to exploit), “High” (complex or specialized knowledge required), or “None” (no exploit available).
  • Privileges Required: This metric reflects the privileges an attacker needs to exploit the vulnerability successfully. It considers whether the attacker requires no privileges, low privileges, or high privileges. The possible values are “None” (no privileges required), “Low” (limited privileges required), or “High” (privileged access required).
  • User Interaction: This metric describes the level of user interaction required to exploit the vulnerability. It determines if the vulnerability can be exploited without any user interaction, requires interaction from a privileged user, or needs interaction from a non-privileged user. The possible values are “None” (no user interaction required), “Required” (user interaction required), or “Unlikely” (user interaction is unlikely).
  • Scope: This metric assesses the impact of the vulnerability on the affected system. It considers whether the vulnerability only affects a component or impacts the entire system. The possible values are “Changed” (the vulnerability impacts a component but does not affect the entire system) or “Unchanged” (the vulnerability affects the entire system).
  • Confidentiality Impact: This metric evaluates the impact on the confidentiality of information if the vulnerability is exploited. It considers the potential loss of confidential information. The possible values are “None” (no loss of confidentiality), “Low” (limited loss of confidentiality), “High” (significant loss of confidentiality), or “Not Defined” (the impact on confidentiality is not defined).
  • Integrity Impact: This metric assesses the impact on the integrity of information if the vulnerability is exploited. It considers the potential modification or tampering of data. The possible values are “None” (no loss of integrity), “Low” (limited loss of integrity), “High” (significant loss of integrity), or “Not Defined” (the impact on integrity is not defined).
  • Availability Impact: This metric evaluates the impact on the availability of the affected system or resources if the vulnerability is exploited. It considers the potential disruption or denial of service. The possible values are “None” (no impact on availability), “Low” (limited impact on availability), “High” (significant impact on availability), or “Not Defined” (the impact on availability is not defined).

These Base Metrics provide a quantitative representation of various aspects of a vulnerability, enabling organizations to assess its severity and prioritize their response accordingly.

Temporal Metrics

  • Exploit Code Maturity: This metric reflects the maturity level of known exploits for the vulnerability. It assesses whether functional exploit code exists and how easily it can be utilized. The possible values are “Not Defined” (no exploit code available), “Unproven” (proof-of-concept or unreliable code), “Proof-of-Concept” (functional exploit code exists), “Functional” (reliable exploit code available), or “High” (widely available exploit code).
  • Remediation Level: This metric considers the availability and effectiveness of an official fix or mitigation for the vulnerability. It evaluates whether a solution exists, how easy it is to apply, and whether it addresses the vulnerability completely. The possible values are “Not Defined” (no official fix available), “Official Fix” (an official fix or patch is available), “Temporary Fix” (a temporary workaround or partial fix exists), “Workaround” (a temporary fix or mitigation is available), or “Unavailable” (no fix or workaround is available).
  • Report Confidence: This metric represents the confidence level in the existence and accuracy of the vulnerability information. It assesses the quality of the source reporting the vulnerability, the credibility of the information, and the degree of verification. The possible values are “Not Defined” (no confidence level defined), “Unknown” (information source is unknown or unreliable), “Uncorroborated” (information is partially verified or unverified), “Confirmed” (information is verified and accurate), or “Not Defined” (confidence level not defined).
  What Is Remote Access?

The Temporal Metrics provide additional context to the vulnerability by considering factors such as the availability of exploit code, the level of remediation or mitigation, and the confidence level in the vulnerability report.

These metrics help organizations assess the current state and potential risks associated with a vulnerability, allowing them to make more informed decisions regarding vulnerability management and prioritization of remediation efforts.

Environmental Metrics

  • Modified Attack Vector: This metric reflects the modified attack vector specific to the environment in which the vulnerability is being assessed. It considers how the environment may impact the vulnerability’s exploitability. The possible values are the same as the Base Metric’s Attack Vector: “Network,” “Adjacent Network,” “Local,” or “Physical.”
  • Modified Attack Complexity: This metric represents the modified attack complexity specific to the assessed environment. It considers the impact of the environment on the difficulty of exploiting the vulnerability. The possible values are the same as the Base Metric’s Attack Complexity: “Low,” “High,” or “None.”
  • Modified Privileges Required: This metric reflects the modified privileges required for exploiting the vulnerability in the assessed environment. It assesses the impact of the environment on the privileges needed for a successful exploit. The possible values are the same as the Base Metric’s Privileges Required: “None,” “Low,” or “High.”
  • Modified User Interaction: This metric represents the modified level of user interaction required to exploit the vulnerability in the assessed environment. It considers the impact of the environment on the necessity of user interaction. The possible values are the same as the Base Metric’s User Interaction: “None,” “Required,” or “Unlikely.”
  • Modified Scope: This metric reflects the modified scope of the vulnerability’s impact in the assessed environment. It assesses how the environment affects the vulnerability’s impact on the system. The possible values are the same as the Base Metric’s Scope: “Changed” or “Unchanged.”
  • Modified Confidentiality Impact: This metric represents the modified impact on confidentiality specific to the assessed environment. It assesses how the environment influences the potential loss of confidential information. The possible values are the same as the Base Metric’s Confidentiality Impact: “None,” “Low,” “High,” or “Not Defined.”
  • Modified Integrity Impact: This metric reflects the modified impact on integrity specific to the assessed environment. It assesses how the environment affects the potential modification or tampering of data. The possible values are the same as the Base Metric’s Integrity Impact: “None,” “Low,” “High,” or “Not Defined.”
  • Modified Availability Impact: This metric represents the modified impact on availability specific to the assessed environment. It assesses how the environment influences the potential disruption or denial of service. The possible values are the same as the Base Metric’s Availability Impact: “None,” “Low,” “High,” or “Not Defined.”

The Environmental Metrics allow for the customization of the CVSS score based on the specific characteristics and configurations of the environment in which the vulnerability exists.

By considering the environmental factors, organizations can better assess a vulnerability’s actual impact and risk in their unique context, enabling more accurate prioritization and decision-making for vulnerability management.

CVSS Scoring and Ratings

Base Score Calculation

The Base Score in CVSS is calculated using the Base Metrics, which we discussed earlier. The Base Score ranges from 0 to 10, with 10 being the most severe. The formula for calculating the Base Score is as follows:

Base Score = (0.6 * Impact + 0.4 * Exploitability – 1.5) * f(Impact)

The Impact represents the impact on the affected system’s confidentiality, integrity, and availability (ranging from 0 to 10). Exploitability represents the ease of exploiting the vulnerability (ranging from 0 to 10). f(Impact) is a function that adjusts the score based on the Impact value, giving higher weights to higher Impact values.

Temporal and Environmental Score Adjustments

After calculating the Base Score, temporal and environmental adjustments can be applied to provide a more accurate representation of the vulnerability’s severity in a specific context.

Temporal adjustments modify the Base Score based on the characteristics of the vulnerability over time. They consider factors such as exploit code availability, remediation level, and report confidence. These adjustments can increase or decrease the Base Score.

  What is Patch Management?

Environmental adjustments modify the Base Score based on the characteristics of the vulnerability in a specific environment. They consider factors such as modified attack vector, attack complexity, privileges required, user interaction, scope, and impact on confidentiality, integrity, and availability. These adjustments customize the Base Score to reflect the specific environment’s impact, potentially increasing or decreasing the score.

CVSS Severity Ratings

CVSS provides severity ratings to help interpret the Base Score and its associated metrics. The severity ratings are as follows:

  • None (0.0): No significant impact or threat.
  • Low (0.1 – 3.9): Low-level impact or threat. Typically, these vulnerabilities are easier to manage and mitigate.
  • Medium (4.0 – 6.9): Moderate-level impact or threat. These vulnerabilities require attention and remediation.
  • High (7.0 – 8.9): High-level impact or threat. These vulnerabilities pose a significant risk and should be addressed urgently.
  • Critical (9.0 – 10.0): Critical-level impact or threat. These vulnerabilities are severe and demand immediate attention and remediation.

The severity ratings provide a quick way to understand the potential severity of a vulnerability based on its Base Score. They help organizations prioritize their response and allocate resources effectively to mitigate the most critical vulnerabilities first.

It’s important to note that temporal and environmental adjustments can impact the severity rating, so it’s crucial to consider the adjusted score along with the severity rating when assessing the severity of a vulnerability in a specific context.

Practical Applications of CVSS

Vulnerability Management

CVSS is widely used in vulnerability management processes. It provides a standardized and objective framework for assessing and prioritizing vulnerabilities. Organizations can use CVSS scores to categorize vulnerabilities based on their severity and prioritize their remediation efforts accordingly. By focusing on vulnerabilities with higher CVSS scores, organizations can effectively allocate their resources and mitigate the most critical security risks.

Risk Assessment

CVSS is valuable for conducting risk assessments. By assigning CVSS scores to vulnerabilities, organizations can assess the potential impact of those vulnerabilities on their systems and networks. The scores help in quantifying and comparing risks, allowing organizations to make informed decisions about risk mitigation strategies. CVSS scores can be integrated into risk assessment frameworks to provide a standardized and consistent approach to evaluating and managing risks associated with vulnerabilities.

Security Patch Prioritization

CVSS scores play a crucial role in prioritizing security patches. When multiple vulnerabilities exist, organizations can use the CVSS scores to determine the order in which patches should be applied.

Higher CVSS scores indicate more severe vulnerabilities, which should be addressed first to minimize the potential impact on the organization’s security posture. CVSS scores help organizations prioritize patching efforts based on the severity of the vulnerabilities, ensuring that critical vulnerabilities are addressed promptly.

In addition to these applications, CVSS scores are also used in vulnerability databases, security advisories, and incident response processes. They aid in communicating the severity of vulnerabilities to various stakeholders, including security teams, management, vendors, and customers. CVSS provides a common language for discussing vulnerabilities and helps in making informed decisions regarding risk management and mitigation strategies.

It’s important to note that while CVSS provides a standardized and objective approach to vulnerability scoring, organizations should also consider their specific business context, system architecture, and additional factors when making decisions based on CVSS scores.

The scores should be used as part of a comprehensive risk management approach, considering other contextual factors to ensure effective security decision-making.

Limitations of CVSS

Subjectivity and Interpretation

CVSS relies on human judgment and interpretation when assessing the various metrics and assigning scores. While CVSS provides guidelines and definitions for each metric, subjective elements can still be involved in the scoring process.

Different assessors may interpret the metrics differently, leading to variations in scores for the same vulnerability. This subjectivity can introduce inconsistencies and make comparing scores across different assessments challenging.

Lack of Contextual Factors

CVSS primarily focuses on the technical aspects of a vulnerability and does not consider broader contextual factors. The scores do not take into account factors such as the value of the affected assets, the sensitivity of the data involved, the specific industry or regulatory requirements, or the organization’s risk tolerance.

  What is Phishing?

These contextual factors are essential in determining a vulnerability’s true impact and risk. Organizations need to supplement CVSS scores with additional analysis and considerations to make well-informed decisions.

Ongoing Evolution

CVSS is a dynamic framework that undergoes regular updates and revisions to address limitations and incorporate feedback from the security community. While this evolution is necessary to improve the accuracy and relevance of the scoring system, it can also introduce complexities.

Organizations must stay updated with the latest versions of CVSS and understand any changes made to ensure consistent and accurate vulnerability assessments. The evolving nature of CVSS means that historical scores may not always be directly comparable to newer scores.

Recognizing these limitations and using CVSS as part of a broader vulnerability management and risk assessment process is important. Organizations should consider additional contextual factors, conduct thorough vulnerability assessments, and utilize expert judgment to make well-rounded decisions.

CVSS should be seen as a valuable tool within the overall security framework rather than the sole determinant of vulnerability severity or risk.

Best Practices for CVSS Usage

Use CVSS as Part of a Holistic Approach

CVSS is a valuable tool, but it should be used as part of a comprehensive and holistic vulnerability management approach. Combine CVSS scores with other risk assessment methodologies, threat intelligence, asset criticality, and business context to make well-informed decisions. Consider additional factors such as the organization’s risk appetite, regulatory requirements, and operational constraints to prioritize vulnerabilities effectively.

Customize CVSS for Your Organization

While CVSS provides a standardized framework, it may not fully capture the specific nuances of your organization’s environment. Customize CVSS by considering contextual factors unique to your organization, such as industry-specific risks, critical assets, and regulatory requirements. Establish internal guidelines or scoring adjustments that align with your risk management strategy and enable more accurate prioritization of vulnerabilities.

Regularly Update Vulnerability Data

CVSS scores are based on vulnerability information that may evolve over time. Stay updated with the latest vulnerability data from reliable sources, such as vulnerability databases, security advisories, and threat intelligence feeds. Regularly update your vulnerability management processes to incorporate new vulnerabilities and their corresponding CVSS scores. This ensures that you have the most accurate and current information to make informed decisions.

Understand the Limitations and Interpretation

Be aware of the limitations of CVSS, as discussed earlier, and understand how the scores should be interpreted. Recognize that CVSS scores are not the sole determinant of vulnerability severity or risk. Use them as a starting point for analysis and decision-making, but supplement them with additional analysis, expert judgment, and organizational context to obtain a more comprehensive understanding of the risks associated with vulnerabilities.

Engage with the Security Community

Participate in discussions and forums within the security community to gain insights and share experiences related to CVSS usage. Engage with vulnerability researchers, vendors, and industry peers to understand their perspectives and best practices. This collaboration can help you enhance your understanding of CVSS and its practical application in real-world scenarios.

By following these best practices, organizations can leverage CVSS effectively as part of their vulnerability management processes, prioritize their mitigation efforts, and make informed decisions to enhance their overall security posture.

CVSS Versions: From v2 to v3.x

Key Differences Between CVSS v2 and v3

  • Scope: CVSS v2 did not explicitly consider the scope of a vulnerability’s impact. CVSS v3 introduced the “Scope” metric, which assesses whether the vulnerability’s impact is limited to the vulnerable component (unchanged scope) or can extend beyond the vulnerable component (changed scope).
  • Impact Metrics: CVSS v2 had separate metrics for assessing the impact on confidentiality, integrity, and availability. In CVSS v3, these metrics were combined into a single “Impact” metric, which considers the impact on all three aspects simultaneously.
  • Exploitability Metrics: CVSS v3 introduced the “Attack Vector” metric to assess the different vectors an attacker can use to exploit a vulnerability. This metric replaced the “Access Vector” metric in CVSS v2.
  • Environmental Metrics: CVSS v3 expanded the environmental metrics, allowing for more customization based on specific environmental factors, such as modified attack vector, modified scope, and modified impact metrics.
  • Scoring Formula: CVSS v3 introduced a new scoring formula that simplified the calculation process and addressed some limitations of the CVSS v2 formula. The updated formula provides a more accurate representation of the severity of vulnerabilities.
