Summary:

Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected are 11.2.0.4, 12.1.0.2, 12.2.0.1, 18c and 19c. Difficult to exploit vulnerability allows low privileged attacker having Create Session privilege with network access via Oracle Net to compromise Java VM. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java VM, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java VM. CVSS 3.0 Base Score 8.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H).
