Vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion (component: Common Security). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Hyperion Infrastructure Technology. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Infrastructure Technology accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Infrastructure Technology accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).
AnalysisAI
Unauthorized data access and modification in Oracle Hyperion Infrastructure Technology 11.2.25.0.000 allows authenticated low-privileged attackers to bypass access controls in the Common Security component via HTTP, gaining read and write access to all critical EPM platform data. The 'Authentication Bypass' tag combined with a PR:L CVSS vector indicates an authorization bypass scenario: a minimal valid account is required but is sufficient to exceed intended access boundaries across confidentiality and integrity dimensions. …
