CVE-2018-2714 in Financial Services Market Risk
Summary
by MITRE
Vulnerability in the Oracle Financial Services Market Risk 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 Market Risk. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Financial Services Market Risk, 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 Market Risk accessible data as well as unauthorized read access to a subset of Oracle Financial Services Market Risk 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-2018-2714 resides within the Oracle Financial Services Market Risk component of Oracle Financial Services Applications, specifically affecting the User Interface subcomponent in version 8.0.x. This represents a critical security weakness that demonstrates how financial services applications can harbor significant risks when proper access controls are not implemented. The vulnerability's classification as easily exploitable indicates that attackers require minimal technical sophistication to leverage this flaw, making it particularly dangerous in production environments where financial data integrity and confidentiality are paramount. The affected system operates under the assumption that network-based attacks can be mitigated through standard security measures, but this vulnerability demonstrates the inadequacy of such approaches when authentication mechanisms are bypassed.
The technical flaw manifests as an authentication bypass vulnerability that allows unauthenticated attackers to access the Oracle Financial Services Market Risk application through HTTP network connections. This weakness creates a pathway for malicious actors to perform unauthorized operations on the system without requiring valid credentials or prior access. The vulnerability's CVSS 3.0 base score of 6.1 reflects the balance between the ease of exploitation and the potential impact on system integrity and confidentiality. The attack vector AV:N indicates network-based access, while AC:L shows low complexity requirements for exploitation. The PR:N designation confirms that no authentication is required for initial access, making this vulnerability particularly dangerous as it can be exploited from any location with network connectivity to the target system. The UI:R component indicates that successful exploitation requires some form of human interaction, suggesting that the attack may involve social engineering elements or user-specific actions that facilitate the exploitation process.
The operational impact of this vulnerability extends beyond the immediate compromise of the Oracle Financial Services Market Risk component, as successful attacks can significantly affect additional products within the Oracle Financial Services Applications suite. This cascading effect demonstrates how vulnerabilities in one component can create ripple effects throughout complex enterprise applications. Attackers can achieve unauthorized update, insert, or delete operations on sensitive data within the affected system, potentially leading to financial losses, regulatory compliance violations, and operational disruptions. The unauthorized read access to a subset of accessible data represents a significant confidentiality breach that could expose sensitive market risk information, trading data, or customer financial details. The combination of integrity and confidentiality impacts creates a particularly dangerous scenario where attackers can both modify and extract valuable information, potentially compromising the entire financial risk management framework.
The vulnerability aligns with CWE-287, which addresses improper authentication issues in software systems, and maps to ATT&CK technique T1110.003 for credential access through exploitation of vulnerabilities. Organizations should implement immediate mitigations including network segmentation to limit access to the affected application, deployment of web application firewalls to monitor and filter HTTP traffic, and implementation of additional authentication layers for critical financial applications. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other components of the Oracle Financial Services Applications suite. The incident highlights the importance of comprehensive security testing during application development phases and the necessity of maintaining up-to-date patches for enterprise financial applications. Organizations should also consider implementing monitoring solutions that can detect unusual access patterns or unauthorized data modifications that may indicate exploitation of similar vulnerabilities. The vulnerability underscores the critical need for layered security approaches that go beyond traditional perimeter-based defenses to protect sensitive financial data within complex enterprise applications.
