CVE-2018-3175 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-2018-3175 resides within Oracle Hyperions Common Events component, specifically within the User Interface subcomponent of the Hyperion suite. This represents a critical security weakness in enterprise financial reporting and business intelligence software that has been widely deployed across organizations. The affected version 11.1.2.4 demonstrates the persistent nature of security flaws in legacy enterprise applications where patches and updates may not be consistently applied across all deployment environments. The vulnerability architecture aligns with CWE-200, which addresses improper exposure of sensitive information, and reflects the broader category of insecure direct object references that can lead to unauthorized data access patterns.
The technical exploitation of this vulnerability requires an unauthenticated attacker to leverage network access through HTTP protocols, making it particularly dangerous as it operates without requiring valid credentials or prior access to the system. The CVSS 3.0 scoring of 6.1 indicates a medium severity threat that combines confidentiality and integrity impacts, with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N clearly demonstrating that the attack requires no privilege escalation but does necessitate user interaction. This user interaction requirement suggests that the exploitation mechanism likely involves social engineering or targeted phishing campaigns where victims must perform specific actions to trigger the vulnerability, potentially through malicious web content or crafted URLs that interact with the vulnerable Common Events interface.
The operational impact of this vulnerability extends beyond the immediate Common Events component, as the CVSS vector indicates a potential for significant impact to additional products within the Hyperion ecosystem. This cascading effect demonstrates how vulnerabilities in one component can compromise the broader enterprise infrastructure, potentially affecting financial reporting systems, data analytics platforms, and related business intelligence tools that depend on the Common Events framework. Attackers who successfully exploit this vulnerability can achieve unauthorized update, insert, or delete operations against sensitive data within the Common Events environment, while also gaining unauthorized read access to subsets of accessible data, creating opportunities for both data corruption and information disclosure attacks.
Organizations affected by this vulnerability should implement immediate mitigations including network segmentation to limit access to the Common Events interface, deployment of web application firewalls to monitor and filter HTTP traffic, and comprehensive user education to recognize potential social engineering attempts. The vulnerability's classification under ATT&CK technique T1190 for exploit public-facing application indicates that defensive measures should focus on application hardening and access control mechanisms. Additionally, security teams must conduct thorough vulnerability assessments to identify all instances of the affected Hyperion version and ensure proper patching procedures are implemented across the enterprise. The vulnerability's characteristics also suggest that monitoring for unusual HTTP request patterns and implementing proper input validation controls can help detect and prevent exploitation attempts. Organizations should also consider implementing network-based intrusion detection systems to identify potential exploitation attempts targeting this specific vulnerability in the Common Events component.
