CVE-2017-3374 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle Advanced Outbound Telephony component of Oracle E-Business Suite (subcomponent: User Interface). Supported versions that are affected are 12.1.1, 12.1.2, 12.1.3, 12.2.3, 12.2.4, 12.2.5 and 12.2.6. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Advanced Outbound Telephony. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Advanced Outbound Telephony, 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 Advanced Outbound Telephony accessible data as well as unauthorized update, insert or delete access to some of Oracle Advanced Outbound Telephony accessible data. CVSS v3.0 Base Score 8.2 (Confidentiality and Integrity impacts).

The vulnerability described in CVE-2017-3374 represents a critical security flaw within Oracle Advanced Outbound Telephony component of the Oracle E-Business Suite, specifically affecting versions 12.1.1 through 12.2.6. This vulnerability resides within the User Interface subcomponent and demonstrates the inherent risks associated with complex enterprise software systems where multiple interconnected modules can create cascading security implications. The vulnerability's classification as easily exploitable indicates that attackers can leverage relatively straightforward techniques to gain unauthorized access, making it particularly dangerous in production environments where such systems handle sensitive business data. The attack vector requires only network access via HTTP, eliminating the need for physical presence or sophisticated network reconnaissance, which significantly broadens the potential attack surface.
The technical implementation of this vulnerability stems from inadequate authentication mechanisms within the Oracle Advanced Outbound Telephony interface, allowing unauthenticated attackers to bypass normal access controls. This flaw operates at the application layer and specifically targets the telephony component's user interface, which serves as an entry point for managing outbound communication systems. The vulnerability's impact extends beyond the immediate component, as successful exploitation can compromise additional Oracle products within the same suite, demonstrating how interconnected enterprise applications can create propagation paths for security breaches. The CVSS v3.0 base score of 8.2 reflects the severity of potential impacts, indicating that attackers can achieve unauthorized access to critical data and gain complete access to all accessible data within the telephony component. This score places the vulnerability in the high-risk category, emphasizing the need for immediate remediation.
The operational impact of CVE-2017-3374 is substantial, as it enables attackers to perform unauthorized operations including data access, modification, insertion, and deletion within the affected Oracle Advanced Outbound Telephony system. The requirement for human interaction from a person other than the attacker suggests that the vulnerability may be exploited through social engineering techniques or by leveraging legitimate user credentials, making detection more challenging. This characteristic aligns with ATT&CK framework concept of privilege escalation and credential access, where initial unauthorized access can lead to broader system compromise. Organizations utilizing affected Oracle E-Business Suite versions face significant risks to their communication infrastructure, potentially allowing attackers to manipulate outbound telephony systems, access sensitive customer information, or disrupt business operations through unauthorized data modifications.
Organizations should implement immediate mitigations including applying Oracle's security patches and updates, restricting network access to the affected components through firewalls and access controls, and monitoring for suspicious network activity. The vulnerability's classification under CWE-287 (Improper Authentication) highlights the fundamental security principle that authentication mechanisms must be robust and properly implemented to prevent unauthorized access. Security teams should conduct comprehensive vulnerability assessments across their entire Oracle E-Business Suite deployment to identify any other potentially affected components, as the interconnected nature of enterprise applications means that vulnerabilities in one area can impact multiple systems. Additionally, implementing network segmentation and limiting direct HTTP access to critical components can significantly reduce the attack surface and provide additional layers of defense against exploitation attempts.
