CVE-2022-21389Network attack vector

Unauthenticated takeover via undisclosed Connection Manager flaw

Published Jan 19, 2022 · Updated Sep 24, 2024

Unspecified vulnerability in Oracle Communications Billing and Revenue Management 12.0.0.3 and 12.0.0.4 allows remote attackers to take over BRM. Oracle identifies the Connection Manager and HTTP exposure but has not disclosed the flawed operation or how crafted input reaches it. Network access alone is sufficient, without authentication or user interaction, and successful exploitation grants control of BRM with potential impact on connected products.
