CRITICAL : Vulnerabilities that can be exploited by an unauthenticated attacker from the Internet or those that break the guest/host Operating System isolation.
IMPORTANT : Vulnerabilities that are not rated critical but whose exploitation results in the complete compromise of confidentiality and/or integrity of user data and/or processing resources through user assistance or by authenticated attackers.
MODERATE : Vulnerabilities where the ability to exploit is mitigated to a significant degree by configuration or difficulty of exploitation, but in certain deployment scenarios could still lead to the compromise of confidentiality, integrity, or availability of user data and/or processing resources.
LOW : All other issues that may or maynot have a security impact. Vulnerabilities where exploitation is believed to be extremely difficult, or where successful exploitation would have minimal impact.
