CVE-2018-3177 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-2018-3177 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, making it susceptible to exploitation by malicious actors. The vulnerability operates at the network level and requires no authentication, allowing attackers to compromise the system through standard HTTP network access. This flaw demonstrates characteristics of a remote code execution vulnerability that could potentially affect a broader ecosystem beyond the immediate component, as indicated by the CVSS score and impact assessment.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the Hyperion Common Events User Interface. Attackers can exploit this weakness through unauthenticated HTTP connections, leveraging the vulnerability to perform unauthorized operations on the affected system. The CVSS 3.0 scoring system assigns this vulnerability a base score of 6.1, indicating a medium severity threat with specific impacts to both confidentiality and integrity. The attack vector AV:N indicates network-based exploitation, while AC:L demonstrates that the attack requires low complexity to execute. The PR:N designation reveals that no privileges are required for the attack, and UI:R indicates that successful exploitation requires human interaction from an unwitting user.
The operational impact of this vulnerability extends beyond simple data access, as it enables attackers to perform unauthorized update, insert, or delete operations on sensitive data within the Hyperion Common Events system. Additionally, the vulnerability allows for unauthorized read access to a subset of accessible data, creating potential exposure of confidential business information. The security implications are particularly concerning given that the vulnerability affects a component that serves as a central hub for event management and reporting within enterprise environments. The potential for cascading effects means that successful exploitation could compromise additional products within the Oracle Hyperion ecosystem, making this vulnerability particularly dangerous in enterprise settings where multiple interconnected systems exist.
Organizations should implement immediate mitigations including network segmentation to limit access to the affected Hyperion Common Events component, applying the vendor-provided security patches as soon as they become available, and implementing robust network monitoring to detect anomalous HTTP traffic patterns. The vulnerability aligns with CWE-284, which addresses improper access control issues, and represents a typical example of how user interface components can serve as attack vectors when proper input validation and authentication mechanisms are insufficient. Security teams should also consider implementing web application firewalls to filter potentially malicious HTTP requests and establish strict access controls to limit exposure. The ATT&CK framework categorizes this vulnerability under the T1190 technique for Exploit Public-Facing Application, emphasizing the importance of regular vulnerability assessments and patch management programs to prevent exploitation.
