CVE-2020-2684Network attack vector

Authenticated disclosure via undisclosed Infrastructure flaw

Published Jan 15, 2020 · Updated Sep 30, 2024

Information disclosure in Oracle FLEXCUBE Universal Banking allows remote authenticated users to read critical banking data via HTTP. Oracle identifies the Infrastructure component but has not published the flawed operation or request field that exposes the data. Low-privileged application access is required; affected releases are 12.0.1 through 12.4.0 and 14.0.0 through 14.3.0, and the reported consequence is read access without data modification or service interruption.
