CVE-2017-3398 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-2017-3398 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's classification as easily exploitable indicates that attackers can leverage network-based HTTP access to compromise the targeted system without requiring authentication credentials. This presents a critical security risk as it allows unauthorized access to sensitive telephony infrastructure that manages outbound communications within enterprise environments.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the User Interface component of Oracle Advanced Outbound Telephony. Attackers can exploit this weakness through HTTP network connections to gain unauthorized access to critical data and potentially manipulate system information. The vulnerability's impact extends beyond the immediate component, as successful exploitation can affect additional Oracle products within the broader EBS environment, creating cascading security implications. The CVSS v3.0 base score of 8.2 reflects the severity of both confidentiality and integrity impacts, indicating that attackers could potentially access all accessible data or perform unauthorized modifications to system information.
The operational impact of this vulnerability is particularly concerning for enterprise organizations relying on Oracle E-Business Suite for their telephony operations. Successful exploitation could result in unauthorized access to sensitive customer communication data, potentially exposing personal information, business communications, and proprietary data flows. The ability to perform unauthorized update, insert, or delete operations creates additional risk for data integrity, allowing attackers to modify or corrupt telephony configurations and communication records. This vulnerability particularly affects organizations that depend on automated outbound calling systems for customer service, marketing campaigns, or business communications, as attackers could disrupt service or manipulate call routing information.
Organizations should implement immediate mitigations including network segmentation to restrict access to Oracle EBS components, applying Oracle's security patches and updates, and implementing robust access controls for HTTP interfaces. The vulnerability aligns with CWE-287 (Improper Authentication) and CWE-352 (Cross-Site Request Forgery) categories, reflecting both authentication flaws and potential session management issues. From an ATT&CK framework perspective, this vulnerability maps to techniques involving initial access through network services and privilege escalation through data manipulation. Regular security monitoring and network intrusion detection systems should be deployed to identify potential exploitation attempts, while administrators should conduct thorough access reviews to ensure only authorized personnel can interact with telephony interfaces. Organizations should also consider implementing web application firewalls to protect against HTTP-based attacks targeting the vulnerable interface components.
