CVE-2017-3402 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-2017-3402 resides within Oracle Advanced Outbound Telephony component of the Oracle E-Business Suite, specifically within the User Interface subcomponent. This weakness affects multiple version ranges including 12.1.1 through 12.2.6, representing a substantial attack surface across the Oracle EBS ecosystem. The vulnerability operates at the application layer and leverages HTTP network protocols for exploitation, making it particularly dangerous as it can be triggered remotely without authentication requirements. The CVSS v3.0 base score of 8.2 indicates a high severity classification that reflects both confidentiality and integrity impacts, suggesting that successful exploitation could lead to unauthorized data access and modification.
This vulnerability represents a critical flaw in Oracle's security architecture where an unauthenticated attacker can compromise the Advanced Outbound Telephony functionality through network-based HTTP access. The attack requires human interaction from users other than the attacker, indicating that social engineering or user manipulation may be necessary to complete the exploitation process. The vulnerability's impact extends beyond just the targeted component as it can significantly affect additional Oracle products within the EBS environment, creating cascading security implications. The technical nature of this flaw suggests a potential input validation or access control weakness within the User Interface component that allows attackers to bypass normal authentication mechanisms and gain unauthorized access to telephony functions.
The operational impact of CVE-2017-3402 is severe and multifaceted, potentially enabling attackers to achieve complete access to all data within the Oracle Advanced Outbound Telephony system. This includes unauthorized access to critical business data, as well as the ability to perform unauthorized updates, inserts, or deletions of information within the telephony accessible data. The vulnerability essentially provides a backdoor into telephony operations that could be exploited to manipulate call routing, access sensitive communications data, or disrupt business continuity. From a compliance standpoint, this vulnerability could result in significant regulatory violations and data breach notifications, particularly in environments handling sensitive customer or financial information.
Security professionals should recognize this vulnerability as a potential candidate for ATT&CK framework techniques related to initial access through web application attacks and privilege escalation. The CWE (Common Weakness Enumeration) classification for this type of vulnerability would likely fall under CWE-287 for improper authentication or CWE-352 for cross-site request forgery, depending on the specific implementation details. Organizations should immediately implement network segmentation to isolate the affected Oracle EBS components, apply the relevant Oracle critical patch updates, and conduct comprehensive security assessments of all telephony-related systems. Additionally, monitoring for suspicious HTTP traffic patterns and implementing web application firewalls can provide additional layers of protection against exploitation attempts. The vulnerability demonstrates the importance of maintaining current security patches and the potential for seemingly isolated component flaws to create widespread system compromise opportunities.
