CVE-2020-2518Network attack vector

Authenticated Java VM takeover

Published Jan 15, 2020 · Updated Sep 30, 2024

Java VM compromise in Oracle Database 11.2.0.4, 12.1.0.2, 12.2.0.1, 18c, and 19c allows remote authenticated users to take over the VM. Oracle identifies the Java VM component and multiple network protocols but has not published the affected function, attacker-controlled input, or incorrect operation. Create Session privilege and a high-complexity attack are required; success grants control of the database Java VM and its accessible resources.
