CVE-2017-3389 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-2017-3389 resides within Oracle Advanced Outbound Telephony component of the Oracle E-Business Suite, specifically within the User Interface subcomponent. This security 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 application layer and presents a critical risk to organizations utilizing these specific versions of Oracle E-Business Suite.
This vulnerability represents a classic authentication bypass issue that allows unauthenticated attackers to gain access to the Oracle Advanced Outbound Telephony functionality through HTTP network connections. The flaw's exploitability is rated as easily exploitable, indicating that attackers do not require specialized tools or extensive technical knowledge to leverage this weakness. The attack vector specifically requires network access via HTTP protocols, making it particularly dangerous in environments where network services are exposed to external threats. The vulnerability's classification under CWE-287 (Improper Authentication) demonstrates the fundamental flaw in the authentication mechanism that permits unauthorized access.
The operational impact of this vulnerability extends beyond the immediate scope of Oracle Advanced Outbound Telephony. Successful exploitation can result in unauthorized access to critical data within the telephony component, potentially exposing sensitive customer information, call records, and telephony configurations. The vulnerability allows for complete access to all accessible data within the Advanced Outbound Telephony subsystem, representing a severe confidentiality breach. Additionally, attackers can perform unauthorized update, insert, or delete operations on data within the affected system, creating integrity risks that could disrupt telephony operations and potentially compromise business continuity. The CVSS v3.0 base score of 8.2 reflects the high severity of both confidentiality and integrity impacts, indicating a serious threat to organizational data security.
The requirement for human interaction from individuals other than the attacker suggests that this vulnerability may involve social engineering components or require specific user actions to complete the exploitation process. This characteristic reduces the automated exploitation potential but does not eliminate the threat entirely. The attack scenario likely involves an attacker gaining initial access through network-based methods and then leveraging human factors to achieve complete system compromise. Organizations should consider implementing additional security controls such as network segmentation, web application firewalls, and user access monitoring to prevent unauthorized access to vulnerable components. The vulnerability's impact on additional products indicates that successful exploitation could potentially affect other Oracle E-Business Suite components, creating cascading security risks that extend beyond the immediate telephony functionality.
Mitigation strategies should include immediate patching of affected Oracle E-Business Suite versions, implementation of network access controls to restrict HTTP access to the vulnerable components, and deployment of intrusion detection systems to monitor for suspicious network activity. Security administrators should also conduct comprehensive vulnerability assessments to identify all instances of affected software within their environment and implement proper access controls to limit exposure. The ATT&CK framework would categorize this vulnerability under techniques related to credential access and privilege escalation, emphasizing the need for layered security approaches that address both network-level and application-level threats. Organizations should also consider implementing security awareness training to reduce the risk of social engineering attacks that could exploit this vulnerability through human interaction requirements.
