Description

Vulnerability in the Oracle Hyperion Financial Reporting product of Oracle Hyperion (component: Server). The supported version that is affected is 11.2.25.0.000. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Hyperion Financial Reporting. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Financial Reporting accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Financial Reporting accessible data. CVSS 3.1 Base Score 6.8 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N).

  "executiveSummary": "A vulnerability has been identified within the Oracle Hyperion Financial Reporting product, specifically affecting the Server component in version 11.2.25.0.000. This security flaw is classified as a difficult-to-exploit vulnerability that allows an unauthenticated remote attacker with network access via the HTTP protocol to compromise the affected system. Successful exploitation of this vulnerability requires human interaction from a victim other than the attacker. When successfully exploited, the vulnerability can result in unauthorized creation, deletion, or modification access to critical data and all accessible Oracle Hyperion Financial Reporting data, as well as unauthorized or complete access to critical data. The CVSS 3.1 base score is 6.8, with significant impacts on confidentiality and integrity, while availability remains unaffected. The CVSS vector is defined as CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N. Organizations deploying the vulnerable version must understand the associated risks to confidentiality and data integrity, ensuring that appropriate defensive measures and monitoring are applied to mitigate potential unauthorized data access and manipulation vectors.",
  "technicalDetails": "The vulnerability resides in the Server component of Oracle Hyperion Financial Reporting version 11.2.25.0.000. The attack vector is network-based (AV:N), meaning that an attacker does not require local access to the target system and can interact with the application remotely via HTTP protocols. The attack complexity is rated as high (AC:H), indicating that successful exploitation requires specific conditions, precise timing, or configuration nuances that make automated or reliable exploitation more challenging. Furthermore, the vulnerability requires no privileges (PR:N) from the attacker prior to exploitation, allowing any unauthenticated external entity to initiate the attack sequence. However, a critical prerequisite for successful exploitation is user interaction (UI:R), meaning an individual other than the attacker must perform a specific action, such as clicking a malicious link or interacting with a manipulated interface element within the application context. The scope of the vulnerability is unchanged (S:U), restricting the impact to the vulnerable component itself without directly breaching underlying hypervisor or separate security domains. In terms of post-exploitation impact, the vulnerability compromises both confidentiality (C:H) and integrity (I:H) at a high level. An attacker who successfully orchestrates the attack flow can gain unauthorized access to critical data and complete access to all data accessible by Oracle Hyperion Financial Reporting. Additionally, the attacker can perform unauthorized creation, deletion, or modification of critical data and enterprise reporting records. The attack flow typically involves the attacker crafting a malicious HTTP payload or scenario that is delivered across the network, which then relies on the targeted user interacting with the application to process the request, ultimately leading to the unauthorized disclosure or manipulation of sensitive financial reporting data."
