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 5.2
 Related exploit range (AccessVector) Local
 Attack complexity (AccessComplexity) Low
 Level of authentication needed (Authentication) Single Instance
 Confidentiality impact None
 Integrity impact Partial
 Availability impact Complete
 Temporal Score 4.3
 Availability of exploit (Exploitability) High
 Type of fix available (RemediationLevel) Official fix
 Level of verification that vulnerability exists (ReportConfidence) Confirmed

NOTE: CVSS version 2.0 vector was used to generate this score.
