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, visit the CVSS
website at: https://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 the
successful exploitation of the issue being scored.
