What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council’s effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, please visit the CVSS website at: http://www.first.org/cvss/.
What are the CVSS scoring metrics that have been used?
| Base Score | 7.2 |
| Related exploit range (AccessVector) | Local |
| Attack complexity (AccessComplexity) | Low |
| Level of authentication needed (Authentication) | None |
| Confidentiality impact | Complete |
| Integrity impact | Complete |
| Availability impact | Complete |
| Temporal Score | 5.6 |
| Availability of exploit (Exploitability) | Proof of concept code |
| Type of fix available (RemediationLevel) | Official fix |
| Level of verification that vulnerability exists (ReportConfidence) | Confirmed |
NOTE: CVSS version 2.0 was used to generate this score.
