CVE-2022-21420Network attack vector

Unauthenticated takeover through undisclosed Core flaw

Published Apr 19, 2022 · Updated Sep 24, 2024

An undisclosed Core flaw in Oracle Coherence 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0 allows remote attackers to take over the service via T3. Oracle has not published the affected Core code path or the incorrect operation it performs on T3 input. Network access to the T3 service is sufficient and requires neither authentication nor user interaction; successful exploitation grants control of Coherence data and service operation.
