CVE-2018-3178 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-2018-3178 resides within Oracle Hyperions Common Events component, specifically within the User Interface subcomponent of the Hyperion suite. This represents a critical security weakness that affects version 11.1.2.4 of the software, making it susceptible to exploitation by unauthenticated attackers who can access the system through standard HTTP protocols. The vulnerability operates at the application layer and demonstrates the dangerous potential of web-based interfaces in enterprise business intelligence platforms where sensitive financial and operational data is processed and stored.
The technical flaw manifests as an insufficient access control mechanism within the Hyperion Common Events User Interface, allowing attackers to perform unauthorized operations against the system without requiring authentication credentials. This vulnerability operates under the Common Weakness Enumeration framework as CWE-284, which specifically addresses improper access control issues in software applications. The attack vector requires network connectivity via HTTP protocol and can be executed without requiring any privileged credentials from the target system, making it particularly dangerous in enterprise environments where such systems may be exposed to external networks.
The operational impact of this vulnerability extends beyond the immediate Common Events component, as successful exploitation can result in significant data compromise across interconnected systems. Attackers can achieve unauthorized update, insert, or delete operations against sensitive data within the affected system, while also gaining unauthorized read access to specific data subsets. The CVSS 3.0 scoring system assigns this vulnerability a base score of 6.1, reflecting the moderate severity level with low attack complexity and the requirement for user interaction. The vector notation AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N indicates that network-based attacks are possible with low complexity, no privilege requirements, but requiring user interaction and potentially causing confidentiality and integrity impacts across the affected system.
The requirement for human interaction distinguishes this vulnerability from fully automated attacks, suggesting that social engineering or targeted phishing campaigns might be necessary to initiate exploitation. This characteristic places the vulnerability within the ATT&CK framework under the T1212 technique for Exploitation for Credential Access, where attackers leverage system vulnerabilities to gain unauthorized access to resources. The potential for cascading impacts across additional products demonstrates the interconnected nature of enterprise business intelligence systems and highlights the importance of proper network segmentation and access controls. Organizations should implement immediate mitigations including network access controls, regular patch management, and monitoring for unauthorized access attempts to prevent exploitation of this vulnerability.
The vulnerability represents a significant concern for financial and enterprise environments where Hyperion systems process sensitive business data, as it provides attackers with the capability to modify or extract confidential information without detection. The combination of low attack complexity and the requirement for minimal privileges makes this vulnerability particularly attractive to threat actors seeking to compromise enterprise financial systems. Security teams should prioritize this vulnerability in their assessment and remediation efforts, particularly in environments where Hyperion systems are exposed to untrusted networks or where proper network segmentation has not been implemented to isolate critical business intelligence applications from general network access.
