CVE-2022-21347Network attack vector

Unauthenticated data modification and partial denial of service

Published Jan 19, 2022 · Updated Sep 24, 2024

Unspecified flaw in Oracle WebLogic Server Core allows remote attackers to alter data and partially interrupt service through T3. Oracle identifies the affected locus only as Core and has not disclosed the faulty operation performed on T3 input. Unauthenticated network access to a T3 listener is sufficient on versions 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0; impact is limited to modifying some accessible data and partially interrupting service.
