CVE-2017-3376 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-2017-3376 resides within the Oracle Advanced Outbound Telephony component of Oracle E-Business Suite, specifically within the User Interface subcomponent. This flaw affects multiple version releases including 12.1.1 through 12.2.6, representing a significant attack surface across the Oracle EBS ecosystem. The vulnerability is classified as easily exploitable, meaning that attackers with network access via HTTP can potentially compromise the targeted component without requiring authentication credentials. This characteristic places the vulnerability at a high risk level given that it can be leveraged by threat actors without prior access to legitimate user accounts or system credentials.
The technical nature of this vulnerability stems from insufficient input validation or access control mechanisms within the User Interface component of Oracle Advanced Outbound Telephony. The flaw allows unauthenticated attackers to potentially gain unauthorized access to sensitive data and perform operations that could compromise both confidentiality and integrity of the system. The vulnerability's impact extends beyond the immediate component, as successful exploitation can affect additional Oracle products within the broader EBS environment. This cascading effect demonstrates how vulnerabilities in one subsystem can create ripple effects throughout an organization's enterprise application infrastructure.
From an operational perspective, the vulnerability presents a critical risk to organizations utilizing Oracle E-Business Suite, particularly those with extensive telephony operations and customer communication systems. The requirement for human interaction from individuals other than the attacker suggests that social engineering or targeted phishing campaigns may be necessary to achieve successful exploitation, though the underlying vulnerability remains accessible to unauthorized network access. Attackers could potentially access critical telephony data including customer information, call logs, and communication records, while also gaining the ability to modify or delete data within the affected system. The CVSS v3.0 base score of 8.2 indicates a high severity level, reflecting the potential for significant data compromise and system integrity violations that could impact business operations and regulatory compliance requirements.
Organizations should implement immediate mitigation strategies including network segmentation to limit access to Oracle E-Business Suite components, deployment of web application firewalls to monitor and filter HTTP traffic, and implementation of network access controls to restrict unauthorized access attempts. The vulnerability aligns with CWE-287 (Improper Authentication) and CWE-352 (Cross-Site Request Forgery) categories, representing weaknesses in authentication mechanisms and potential CSRF attack vectors. Security teams should also consider implementing monitoring solutions to detect anomalous access patterns and establish incident response procedures for potential exploitation attempts. The ATT&CK framework categorizes this vulnerability under T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS) as attackers may utilize public-facing interfaces to establish initial access. Regular patch management processes should be prioritized to ensure timely deployment of Oracle security patches, while comprehensive security assessments should evaluate the overall attack surface of Oracle E-Business Suite implementations to identify additional vulnerabilities that may compound the risks associated with this particular flaw.
