CVE-2018-3049 in FLEXCUBE Enterprise Limits
Summary
by MITRE
Vulnerability in the Oracle FLEXCUBE Enterprise Limits and Collateral Management component of Oracle Financial Services Applications (subcomponent: Infrastructure). Supported versions that are affected are 12.3.0, 14.0.0 and 14.1.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle FLEXCUBE Enterprise Limits and Collateral Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle FLEXCUBE Enterprise Limits and Collateral Management, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle FLEXCUBE Enterprise Limits and Collateral Management accessible data as well as unauthorized read access to a subset of Oracle FLEXCUBE Enterprise Limits and Collateral Management accessible data. CVSS 3.0 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2018-3049 resides within Oracle FLEXCUBE Enterprise Limits and Collateral Management, a critical component of Oracle Financial Services Applications that manages financial risk exposure and collateral arrangements for enterprise clients. This vulnerability specifically affects versions 12.3.0, 14.0.0, and 14.1.0 of the software, representing a significant security gap in financial services infrastructure that could compromise the integrity and confidentiality of sensitive banking data. The flaw operates within the Infrastructure subcomponent of the broader FLEXCUBE suite, indicating that the vulnerability stems from core system architecture rather than application-specific functionality.
The technical nature of this vulnerability manifests as an easily exploitable weakness that requires minimal privileges to exploit, specifically allowing attackers with low privilege levels and network access via HTTP to compromise the targeted system. This represents a particularly concerning security gap because it enables attackers to gain unauthorized access to critical financial data without requiring elevated system privileges. The vulnerability's classification as requiring human interaction from a person other than the attacker suggests that social engineering or targeted phishing attacks may be necessary to initiate the exploitation process, though the actual attack vector remains accessible through standard web protocols. The CVSS 3.0 base score of 5.4 indicates a moderate severity level that reflects the potential for unauthorized data modification and read access to sensitive financial information.
From an operational impact perspective, successful exploitation of this vulnerability can result in unauthorized update, insert, or delete operations against the affected data within Oracle FLEXCUBE Enterprise Limits and Collateral Management, potentially allowing attackers to manipulate financial exposure limits and collateral arrangements that could have significant financial implications for both the institution and its clients. Additionally, attackers can achieve unauthorized read access to subsets of accessible data, potentially exposing sensitive financial information including customer exposure limits, collateral details, and risk management parameters. The security impact extends beyond the immediate component, as attacks may significantly affect additional products within the Oracle Financial Services Applications ecosystem, indicating potential cascading effects throughout the financial institution's operational infrastructure.
The vulnerability aligns with CWE-284 (Improper Access Control) and follows patterns consistent with ATT&CK technique T1213.002 (Data from Cloud Storage) and T1071.004 (Application Layer Protocol: DNS) as attackers can leverage network-based access to manipulate financial data through standard HTTP protocols. Organizations should implement immediate mitigations including applying Oracle's security patches, implementing network segmentation to limit access to the affected components, and establishing enhanced monitoring for unusual data access patterns. The vulnerability's classification as requiring human interaction suggests that user awareness training and robust access control policies should be prioritized alongside technical mitigations to prevent successful exploitation attempts. Organizations should also consider implementing network-level controls to restrict access to the affected application components and maintain detailed audit logs to detect potential unauthorized access attempts.
