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 between 0 and 10 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/.

When calculating CVSS scores, McAfee has adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by successful exploitation of the issue being scored
What are the CVSS scoring metrics that have been used?
 Base Score 10.0
 Attack Vector (AV) Network (N)
 Attack Complexity (AC) Low (L)
 Privileges Required (PR) None (N)
 User Interaction (UI) None (N)
 Scope (S) Changed (C)
Confidentiality (C) High (H)
Integrity (I) High (H)
Availability (A) High (H)
 Temporal Score (Overall) 9.0
 Exploitability (E) Proof-of-Concept (P)
 Remediation Level (RL) Official Fix (O)
 Report Confidence (RC) Confirmed (C)

NOTE: The below CVSS version 3.0 vector was used to generate this score.
