CVE-2022-21601Network attack vector

Unauthenticated data disclosure and service interruption

Published Oct 18, 2022 · Updated Sep 24, 2024

Information disclosure in Oracle Communications BRM 12.0.0.4.0 through 12.0.0.7.0 allows remote attackers to read data via TCP. Oracle identifies Connection Manager as the affected locus but has not published the specific operation that mishandles untrusted TCP input. No authentication or user interaction is required; successful attacks expose a subset of accessible data and cause a partial service interruption.
