Supported versions that are affected are 15.0.0.0.0, 15.0.1.0.0, 15.1.0.0.0 and  15.2.0.0.0. Difficult to exploit vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Oracle Communications BRM - Elastic Charging Engine executes to compromise Oracle Communications BRM - Elastic Charging Engine.  Successful attacks of this vulnerability can result in  unauthorized creation, deletion or modification access to critical data or all Oracle Communications BRM - Elastic Charging Engine accessible data as well as  unauthorized read access to a subset of Oracle Communications BRM - Elastic Charging Engine accessible data. CVSS 3.1 Base Score 5.9 (Confidentiality and Integrity impacts).
