Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Hyperion Calculation Manager accessible data. CVSS 3.1 Base Score 6.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
AnalysisAI
Unauthenticated confidentiality exposure in Oracle Hyperion Calculation Manager 11.2.25.0.000 permits any attacker with access to the same physical network segment to obtain complete read access to all data the application can access, including sensitive financial planning and business rule data. The authentication bypass (tagged explicitly by Oracle) requires no credentials and no user interaction, making it trivially exploitable by any host co-resident on the adjacent LAN or VLAN. …
