CVE-2018-3176 in Hyperion
Summary
by MITRE
Vulnerability in the Hyperion Common Events component of Oracle Hyperion (subcomponent: User Interface). The supported version that is affected is 11.1.2.4. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Hyperion Common Events. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Hyperion Common Events, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Hyperion Common Events accessible data as well as unauthorized read access to a subset of Hyperion Common Events accessible data. CVSS 3.0 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2018-3176 resides within Oracle Hyperions Common Events component, specifically within the User Interface subcomponent of the Hyperion suite. This represents a critical security flaw that affects version 11.1.2.4 of the software. The vulnerability manifests as an easily exploitable weakness that can be leveraged by unauthenticated attackers who possess network access through HTTP protocols. The attack vector is particularly concerning as it requires minimal prerequisites for exploitation, making it accessible to a broad range of threat actors including automated scanning tools and malicious individuals seeking to compromise enterprise financial and business intelligence systems.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the Common Events User Interface component. Attackers can exploit this weakness to gain unauthorized access to the system's data management functions, specifically enabling them to perform unauthorized update, insert, or delete operations on sensitive data within the Common Events environment. Additionally, the vulnerability permits unauthorized read access to specific subsets of data that should otherwise be protected from public access. This dual impact on both confidentiality and integrity aligns with CWE-284, which addresses improper access control issues, and reflects the core principles of the Common Weakness Enumeration framework for identifying security flaws.
From an operational perspective, the vulnerability's impact extends beyond the immediate Common Events component to potentially affect additional products within the Hyperion ecosystem. This cascading effect demonstrates how vulnerabilities in one component can compromise the broader enterprise infrastructure, particularly in organizations that rely heavily on integrated financial reporting and business intelligence platforms. The CVSS 3.0 score of 6.1 indicates a moderate to high severity threat level, with the base vector showing network accessibility (AV:N), low attack complexity (AC:L), no privilege requirements (PR:N), and requiring human interaction (UI:R) from users other than the attacker. The scope of impact (S:C) suggests that while the vulnerability is contained within Common Events, it can affect other systems through the attack chain.
The security implications of this vulnerability are significant for organizations using Oracle Hyperion solutions, as it provides attackers with the capability to manipulate financial data and potentially disrupt business operations. The requirement for human interaction indicates that the attack may involve social engineering elements or require users to perform specific actions that trigger the vulnerability, though this does not mitigate the overall risk. Organizations must consider implementing network segmentation, access controls, and regular security monitoring to detect and prevent exploitation attempts. The vulnerability also highlights the importance of maintaining up-to-date software patches and following security best practices as outlined in the ATT&CK framework for enterprise security operations. Given the nature of financial and business intelligence data handled by Hyperion systems, this vulnerability represents a substantial risk to data integrity and organizational security posture, particularly when considering the potential for data manipulation that could affect critical business decisions and regulatory compliance requirements.
