CVE-2017-2721 : 상세 정보

Base: Exploitabilty Metrics

The Exploitability metrics reflect the characteristics of the thing that is vulnerable, which we refer to formally as the vulnerable component.

This metric reflects the context by which vulnerability exploitation is possible.

This metric describes the conditions beyond the attacker's control that must exist in order to exploit the vulnerability.

This metric describes the level of privileges an attacker must possess before successfully exploiting the vulnerability.

This metric captures the requirement for a user, other than the attacker, to participate in the successful compromise of the vulnerable component.

Base: Scope Metrics

An important property captured by CVSS v3.0 is the ability for a vulnerability in one software component to impact resources beyond its means, or privileges.

Formally, Scope refers to the collection of privileges defined by a computing authority (e.g. an application, an operating system, or a sandbox environment) when granting access to computing resources (e.g. files, CPU, memory, etc). These privileges are assigned based on some method of identification and authorization. In some cases, the authorization may be simple or loosely controlled based upon predefined rules or standards. For example, in the case of Ethernet traffic sent to a network switch, the switch accepts traffic that arrives on its ports and is an authority that controls the traffic flow to other switch ports.

Base: Impact Metrics

The Impact metrics refer to the properties of the impacted component.

This metric measures the impact to the confidentiality of the information resources managed by a software component due to a successfully exploited vulnerability.

This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information.

This metric measures the impact to the availability of the impacted component resulting from a successfully exploited vulnerability.

Temporal Metrics

The Temporal metrics measure the current state of exploit techniques or code availability, the existence of any patches or workarounds, or the confidence that one has in the description of a vulnerability.

Environmental Metrics
