CVE-2021-2428Network attack vector

Unauthenticated takeover

Published Jul 20, 2021 · Updated Sep 25, 2024

An unspecified Core flaw in Oracle Coherence 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0 allows remote attackers to take over the service. Oracle has not disclosed the affected function or the operation performed incorrectly on protocol input. Exploitation requires unauthenticated network access over T3 or IIOP and high attack complexity; success grants control of Coherence with complete data and service impact.
