        exploit this over 'Multiple' protocol can result in unauthorized read access to a subset of Java SE
        accessible data. This issue affects the 'Advanced Management Console' component. (CVE-2020-2764)
    
      - Oracle Java SE and Java SE Embedded are prone to unauthorized write/read access vulnerability. An
        unauthenticated remote attacker over 'HTTPS' can read, update, insert or delete access to some of Java SE
        accessible data. This issue affects the 'JSSE' component. (CVE-2020-2767)
