CVE-2017-3388 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 identified as CVE-2017-3388 resides within Oracle Advanced Outbound Telephony component of the Oracle E-Business Suite, specifically within the User Interface subcomponent. This flaw affects multiple versions including 12.1.1 through 12.2.6, representing a significant attack surface across the Oracle E-Business Suite ecosystem. The vulnerability operates at the network level and can be exploited through HTTP protocols without requiring authentication, making it particularly dangerous as it eliminates the need for valid credentials or privileged access. The CVSS v3.0 base score of 8.2 indicates a high-severity threat that could result in substantial data compromise and system integrity violations.
The technical exploitation of this vulnerability occurs through an easily accessible network interface that allows unauthenticated attackers to compromise the Advanced Outbound Telephony component. The flaw specifically enables attackers to gain unauthorized access to critical data within the telephony system and potentially achieve complete access to all accessible data within the component. Additionally, successful exploitation can provide unauthorized capabilities to update, insert, or delete data within the affected system, creating both confidentiality and integrity risks. The vulnerability's impact extends beyond just the immediate component, as attacks may significantly affect other products within the Oracle E-Business Suite environment, demonstrating the interconnected nature of enterprise applications and their potential for cascading security failures.
From an operational perspective, this vulnerability represents a substantial risk to organizations utilizing Oracle E-Business Suite deployments. The requirement for human interaction from users other than the attacker suggests that social engineering or targeted phishing attacks may be employed to facilitate exploitation, making the threat more sophisticated than simple automated attacks. The potential for unauthorized access to critical telephony data combined with the ability to modify system data creates a dual threat that could disrupt business operations while simultaneously exposing sensitive information. Organizations with telephony systems that handle customer communications, call routing, or business-critical communications are particularly vulnerable to this type of attack, as the compromise could lead to service disruption, data breaches, or unauthorized access to communication channels.
The vulnerability aligns with CWE-284 (Improper Access Control) and demonstrates characteristics consistent with ATT&CK technique T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS). Organizations should implement immediate mitigations including network segmentation to restrict access to the affected telephony interfaces, deployment of web application firewalls to monitor and filter HTTP traffic, and implementation of network access controls to limit exposure. Regular patching and vulnerability assessments should be conducted to identify similar weaknesses across the Oracle E-Business Suite environment. Additionally, monitoring for unusual access patterns or unauthorized data modifications should be enhanced to detect potential exploitation attempts. The attack surface of this vulnerability emphasizes the importance of comprehensive security controls that address not just individual components but also the broader enterprise application ecosystem that these components inhabit, ensuring that security measures are implemented across all layers of the information technology infrastructure.
