CVE-2018-2719 in Financial Services Hedge Management
Summary
by MITRE
Vulnerability in the Oracle Financial Services Hedge Management and IFRS Valuations component of Oracle Financial Services Applications (subcomponent: User Interface). The supported version that is affected is 8.0.x. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Financial Services Hedge Management and IFRS Valuations. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Financial Services Hedge Management and IFRS Valuations, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Financial Services Hedge Management and IFRS Valuations accessible data as well as unauthorized read access to a subset of Oracle Financial Services Hedge Management and IFRS Valuations 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-2018-2719 affects the Oracle Financial Services Hedge Management and IFRS Valuations component within Oracle Financial Services Applications version 8.0.x. This represents a critical security flaw located in the User Interface subcomponent that exposes organizations to significant financial and operational risks. The vulnerability's classification as easily exploitable indicates that attackers can leverage it with minimal technical sophistication, making it particularly dangerous for financial institutions that rely on these systems for critical risk management and accounting functions. The attack vector operates through HTTP network access, eliminating the need for authentication credentials and allowing remote exploitation from any network location.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the user interface layer of the financial services applications. Attackers can exploit this weakness to perform unauthorized operations including data modification, insertion, and deletion within the affected systems. The vulnerability's impact extends beyond the immediate component as it can affect additional products within the Oracle Financial Services ecosystem, creating cascading security implications across an organization's financial infrastructure. This interconnected nature of the vulnerability means that a successful compromise of one component can potentially lead to broader system infiltration and data corruption.
The operational impact of this vulnerability is severe for financial institutions managing hedge positions and IFRS valuations, as these systems contain sensitive financial data that directly affects regulatory compliance and business operations. The CVSS 3.0 score of 6.1 reflects the moderate to high risk level with confidentiality and integrity impacts rated as low, indicating that while the direct financial impact may be moderate, the potential for data manipulation and unauthorized access creates significant business continuity risks. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted phishing attacks may be employed to facilitate exploitation, making the vulnerability even more challenging to defend against. This aspect aligns with ATT&CK technique T1566 for social engineering and demonstrates the multi-layered approach required for effective defense.
Organizations should implement immediate mitigations including network segmentation to limit access to affected systems, disabling unnecessary HTTP services, and applying the relevant Oracle security patches as soon as they become available. The vulnerability's classification under CWE 284 (Improper Access Control) and its alignment with ATT&CK techniques for privilege escalation and data manipulation highlight the need for comprehensive security controls beyond simple patch management. Regular security assessments and monitoring of network traffic for suspicious HTTP activity should be implemented to detect potential exploitation attempts. Additionally, organizations should conduct thorough vulnerability assessments across their entire Oracle Financial Services Applications environment to identify and remediate similar weaknesses that may exist in other components of the suite.
