CVE-2020-2685Network attack vector

Unauthenticated data access via undisclosed HTTP flaw

Published Jan 15, 2020 · Updated Sep 30, 2024

Authentication bypass in Oracle FLEXCUBE Universal Banking 12.0.1 through 12.4.0 and 14.0.0 through 14.3.0 allows remote attackers to read and modify accessible banking data via HTTP. Oracle has not published the vulnerable component's specific operation or endpoint, so the mechanism remains undisclosed. Exploitation requires a person other than the attacker to interact with the service, and reported impact is limited to unauthorized confidentiality and integrity access without service interruption.
