CVE-2022-21570Network attack vector

Unauthenticated denial of service via T3 IIOP

Published Jul 19, 2022 · Updated Sep 24, 2024

Denial-of-service vulnerability in Oracle Coherence Core 3.7.1.0, 12.2.1.3.0, 12.2.1.4.0 and 14.1.1.0.0 allows remote attackers via T3 or IIOP. Oracle has not published the specific code locus or unsafe operation responsible for processing untrusted T3/IIOP input. No authentication or user interaction is required; exploitation can hang the Coherence service or cause repeatable crashes, interrupting availability without reported data disclosure or modification.
