CVE-2017-10359 in Hyperion BI+
Summary
by MITRE
Vulnerability in the Oracle Hyperion BI+ component of Oracle Hyperion (subcomponent: UI and Visualization). The supported version that is affected is 11.1.2.4. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Hyperion BI+. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Hyperion BI+ accessible data as well as unauthorized read access to a subset of Oracle Hyperion BI+ accessible data. CVSS 3.0 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N).

The vulnerability identified as CVE-2017-10359 resides within Oracle Hyperion BI+ component, specifically affecting the UI and Visualization subcomponent. This represents a significant security weakness in enterprise business intelligence software that serves as a critical data visualization and reporting platform for organizations. The affected version 11.1.2.4 demonstrates the persistence of security flaws in legacy enterprise software systems, where outdated components continue to expose organizations to cyber threats despite being supported. The vulnerability operates at the application layer, targeting the user interface components that handle data presentation and interaction within the Hyperion BI+ environment.
The technical flaw manifests as an authentication bypass vulnerability that operates through the HTTP protocol, allowing unauthenticated attackers to exploit the system without requiring valid credentials. This weakness stems from insufficient validation mechanisms within the UI and visualization components that fail to properly authenticate user requests. The vulnerability requires network access and can be exploited through standard HTTP communication channels, making it particularly dangerous as it can be targeted from external networks without requiring physical access to the organization's infrastructure. The CVSS score of 5.4 indicates a medium severity threat that combines both confidentiality and integrity impacts, suggesting that attackers can potentially modify or delete data while also gaining read access to sensitive information.
The operational impact of this vulnerability extends beyond simple data exposure, as successful exploitation enables attackers to perform unauthorized update, insert, and delete operations on specific portions of the Hyperion BI+ data repository. This creates a scenario where malicious actors could alter financial reports, business metrics, or analytical data that organizations rely upon for decision-making processes. Additionally, the unauthorized read access allows for data exfiltration of sensitive business intelligence, potentially exposing competitive information, strategic plans, or confidential operational data. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted phishing campaigns might be necessary to initially gain access to the system, though once the vulnerability is triggered, the attacker can operate without further user involvement.
Organizations should implement immediate mitigations including network segmentation to isolate Hyperion BI+ components from general network access, deployment of web application firewalls to monitor and filter HTTP traffic, and comprehensive network monitoring to detect anomalous access patterns. The vulnerability aligns with CWE-287 which addresses improper authentication issues, and maps to ATT&CK technique T1190 for exploitation of remote services through HTTP protocols. Regular security assessments and patch management procedures should be prioritized to address similar vulnerabilities in legacy enterprise systems, as this flaw demonstrates the ongoing threat posed by outdated software components that continue to operate in production environments without proper security updates. Organizations must also consider implementing multi-factor authentication mechanisms and privileged access management controls to reduce the risk of unauthorized access to critical business intelligence systems.
