This tool is used to calculate a specific threat/vulnerability's CVSS score. Please select the appropriate options below, click "Calculate Score," and the CVSS score will be displayed. Use of this calculator is subject to the disclaimer below.
 
Base Parameters
 

Once discovered, analyzed, and catalogued, there are certain aspects of a vulnerability that do not change, assuming the initial information is complete and correct. These immutable characteristics will not change over time, nor in different environments. The base metric group captures the access to and impact on the target.

 
Access Vector
Access Complexity
Authentication
Confidentiality Impact
Integrity Impact
Availability Impact
Base Score:
9.0
 
Temporal Parameters
 

As a vulnerability ages, certain intrinsic characteristics will change with time. In many cases, when a vulnerability is first discovered, the number of vulnerable systems will be at or close to its peak, while the availability of exploit and remedial information will be at its lowest point. As time progresses, patch information will become more available and more systems will be fixed as more exploits occur, driving the need for the fix. Eventually, the number of vulnerable systems will reach its low point as remedial information reaches its high point. The CVSS temporal metrics group captures these characteristics of a vulnerability that change over time.

 
Exploitability
Remediation Level
Report Confidence
Temporal Score:
7.4
 
Environmental Parameters
 

Different user environments can have an immense bearing on how (or if) a vulnerability affects a given information system and its stakeholders. The CVSS environmental metrics group captures characteristics of vulnerabilities that are tied to system distribution and network environment.

ENDORSEMENT

Cisco endorses and subscribes to the vulnerability guidelines outlined by the National Infrastructure Advisory Council (NIAC). The NIAC commissioned the development of the Common Vulnerability Scoring System (CVSS), which is currently maintained by FIRST (Forum of Incident Response and Security Teams), www.first.org, and was a combined effort involving many companies, including Cisco Systems, Inc.
