CVE-2019-2671 in CRM Technical Foundation
Summary
by MITRE
Vulnerability in the Oracle CRM Technical Foundation component of Oracle E-Business Suite (subcomponent: Preferences). Supported versions that are affected are 12.1.3, 12.2.3, 12.2.4, 12.2.5, 12.2.6, 12.2.7 and 12.2.8. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle CRM Technical Foundation. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle CRM Technical Foundation, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle CRM Technical Foundation accessible data as well as unauthorized update, insert or delete access to some of Oracle CRM Technical Foundation accessible data. CVSS 3.0 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2019-2671 resides within the Oracle CRM Technical Foundation component of Oracle E-Business Suite, specifically affecting the Preferences subcomponent. This weakness manifests in versions 12.1.3 through 12.2.8, representing a significant security gap that impacts organizations utilizing Oracle's enterprise resource planning solutions. The vulnerability operates at the foundational level of the CRM system, making it particularly dangerous as it can serve as a gateway for broader compromise across the entire E-Business Suite ecosystem. The affected component handles user preferences and system configuration settings, which are critical for maintaining proper access controls and operational integrity within enterprise environments.
The technical flaw in CVE-2019-2671 constitutes an authentication bypass vulnerability that allows unauthenticated attackers to exploit the system through standard HTTP network connections. This vulnerability operates with a CVSS base score of 8.2, indicating high severity with significant confidentiality and integrity impacts. The attack vector requires network access via HTTP and can be executed without requiring prior authentication credentials. However, the exploitation process necessitates human interaction from users other than the attacker, suggesting that the vulnerability may be triggered through social engineering or targeted phishing campaigns that prompt users to interact with malicious payloads. The vulnerability's classification under CWE-287 (Improper Authentication) and its alignment with ATT&CK technique T1078 (Valid Accounts) demonstrates how this weakness can be leveraged to establish persistent access to enterprise systems.
The operational impact of this vulnerability extends far beyond the immediate compromise of the CRM Technical Foundation component. Successful exploitation can result in unauthorized access to critical data within the Oracle CRM system, potentially exposing sensitive customer information, financial records, and business intelligence. The vulnerability's ability to grant complete access to all accessible data within the foundation component represents a severe threat to data confidentiality and integrity. Additionally, attackers can gain unauthorized update, insert, or delete access to specific data within the system, enabling them to modify or corrupt critical business information. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) indicates that while the attack requires network access and low complexity, the potential for significant impact is high. The score reflects that the vulnerability affects critical system components and can lead to data exposure, though the integrity impact is moderate due to the potential for data modification without complete system compromise. Organizations utilizing affected Oracle E-Business Suite versions face substantial risk of data breaches and operational disruption, particularly given the widespread adoption of Oracle CRM solutions across enterprise environments.
Mitigation strategies for CVE-2019-2671 should prioritize immediate implementation of Oracle's security patches and updates, as these address the root cause of the authentication bypass vulnerability. Network segmentation and access controls should be implemented to limit exposure of the affected components to untrusted networks, reducing the attack surface available to potential adversaries. Organizations should also enhance their monitoring capabilities to detect anomalous access patterns or unauthorized modifications to preference settings within the CRM system. Regular security assessments and vulnerability scanning should be conducted to identify additional weaknesses in the E-Business Suite environment, as this vulnerability may indicate broader authentication or authorization issues. The implementation of intrusion detection systems and security information event management solutions can provide early warning of exploitation attempts. Additionally, user education and awareness programs should be strengthened to reduce the risk of social engineering attacks that could leverage this vulnerability, particularly given that successful exploitation requires human interaction. Organizations should also consider implementing additional authentication controls and multi-factor authentication mechanisms to provide defense in depth against potential compromise of the affected system components.
