Vulnerability in the Oracle Hyperion Calculation Manager product of Oracle Hyperion (component: Security). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Oracle Hyperion Calculation Manager executes to compromise Oracle Hyperion Calculation Manager. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Hyperion Calculation Manager accessible data as well as unauthorized read access to a subset of Oracle Hyperion Calculation Manager accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N).
