The July 2020 Critical Patch Update is the first Critical Patch Update release to leverage version 3.1 of the Common Vulnerability Scoring System (CVSS), which supersedes version 3.0 which has been used in Oracle’s security advisories since April 2016. The most significant difference between CVSS versions 3.0 and 3.1 is a change in the definition of ‘Attack Complexity.’ In version 3.0, Attack Complexity considered whether a vulnerability could only be exploited against the system being attacked in a certain configuration. If so, Attack Complexity was rated ‘High.’ In CVSS version 3.1, if a specific configuration is required for an attack to succeed, the system being attacked is assumed to be in that configuration for the purposes of scoring the vulnerability. As a result, a vulnerability with a CVSS version 3.0 score that has an Attack Complexity of High purely because a specific configuration was required for the attack to succeed will now have an Attack Complexity of Low when scored with CVSS version 3.1, thus resulting in a higher Base Score.
