CVE-2020-14768 in Hyperion Analytic Provider Services
Summary
by MITRE • 10/21/2020
Vulnerability in the Hyperion Analytic Provider Services product of Oracle Hyperion (component: Smart View Provider). The supported version that is affected is 11.1.2.4. Difficult to exploit vulnerability allows low privileged attacker with access to the physical communication segment attached to the hardware where the Hyperion Analytic Provider Services executes to compromise Hyperion Analytic Provider Services. 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 Hyperion Analytic Provider Services accessible data as well as unauthorized read access to a subset of Hyperion Analytic Provider Services accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Hyperion Analytic Provider Services. CVSS 3.1 Base Score 4.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L).

The vulnerability identified as CVE-2020-14768 resides within Oracle Hyperion's Analytic Provider Services component known as Smart View Provider, specifically affecting version 11.1.2.4. This represents a significant security weakness that operates at the network communication layer, where an attacker with physical access to the network segment connected to the Hyperion Analytic Provider Services hardware can exploit this flaw. The vulnerability's classification as difficult to exploit indicates that while it requires specific conditions and circumstances, it remains a genuine threat to organizations utilizing this particular version of the software. The attack vector requires an attacker to be positioned on the same physical network segment, which limits the scope but does not eliminate the risk, particularly in environments where network segmentation is not properly implemented or maintained.
The technical nature of this vulnerability stems from insufficient security controls within the communication protocols used by the Hyperion Analytic Provider Services. The flaw allows for unauthorized modifications to data through update, insert, and delete operations, while simultaneously enabling unauthorized read access to sensitive data subsets. Additionally, the vulnerability can facilitate partial denial of service conditions that impact the availability of the service. This multi-faceted impact aligns with the CVSS 3.1 scoring system which assigns a base score of 4.3, reflecting the combination of confidentiality, integrity, and availability risks. The attack complexity is rated as high due to the requirement for physical network access, while the privilege requirement is low, suggesting that even unauthenticated attackers with network access can potentially exploit this vulnerability.
The operational impact of this vulnerability extends beyond simple data compromise, as it affects the fundamental security posture of organizations relying on Hyperion Analytic Provider Services for business intelligence and financial reporting. The requirement for human interaction from someone other than the attacker indicates that social engineering or insider threats could potentially be leveraged to compound the attack. This vulnerability is particularly concerning in enterprise environments where Hyperion systems are used for critical financial data processing and analysis, as unauthorized data modifications could lead to significant financial discrepancies and regulatory compliance issues. Organizations utilizing this software version face potential exposure to data integrity violations, unauthorized access to sensitive financial information, and service availability disruptions that could impact business operations and decision-making processes.
Mitigation strategies for CVE-2020-14768 should focus on implementing robust network segmentation controls to prevent unauthorized physical access to the network segments hosting Hyperion Analytic Provider Services. Organizations should ensure that proper network access controls are in place, including the implementation of network access control lists and firewall rules that limit communication to authorized systems only. The vulnerability's classification as a network-based attack emphasizes the importance of physical security measures and network monitoring to detect unauthorized access attempts. Regular security assessments and vulnerability scanning should be conducted to identify and remediate similar issues within the Hyperion ecosystem. Additionally, implementing network intrusion detection systems and monitoring for unusual network activity can help identify potential exploitation attempts. This vulnerability aligns with CWE-284 (Improper Access Control) and may map to ATT&CK techniques involving network infiltration and privilege escalation, highlighting the need for comprehensive security controls that address both physical and logical access controls within enterprise environments.
