CVE-2017-3391 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 described in CVE-2017-3391 represents a critical security flaw within Oracle Advanced Outbound Telephony component of the Oracle E-Business Suite ecosystem. This vulnerability specifically affects the User Interface subcomponent and impacts multiple supported versions including 12.1.1 through 12.2.6, creating a substantial attack surface across various Oracle E-Business Suite deployments. The vulnerability classification as easily exploitable indicates that attackers can leverage this weakness without requiring specialized skills or extensive resources, making it particularly dangerous for organizations that have not implemented proper network segmentation or access controls.
The technical nature of this vulnerability stems from insufficient authentication mechanisms within the Oracle Advanced Outbound Telephony interface, allowing unauthenticated attackers to gain network access via HTTP protocols. This weakness creates a pathway for malicious actors to compromise the telephony component without requiring valid credentials or prior access to the system. The vulnerability's design flaw exists within the web interface layer where proper authentication checks are either absent or inadequately implemented, enabling attackers to directly interact with telephony functions through standard web protocols.
From an operational perspective, the impact of this vulnerability extends beyond the immediate telephony component to potentially affect additional Oracle products within the E-Business Suite environment. This interconnected nature of Oracle applications means that successful exploitation could provide attackers with access to broader organizational data and system functionalities. The CVSS v3.0 base score of 8.2 reflects the severity of potential consequences including unauthorized access to critical data, complete access to all accessible data, and unauthorized modification capabilities through update, insert, or delete operations. These capabilities represent a significant threat to both data confidentiality and integrity within enterprise environments.
The requirement for human interaction from individuals other than the attacker suggests that social engineering or targeted phishing techniques may be necessary to initiate the attack, potentially through manipulation of legitimate users into performing actions that facilitate exploitation. This aspect of the vulnerability aligns with ATT&CK techniques involving social engineering and user manipulation, where attackers leverage human factors to achieve system compromise. The vulnerability's impact on data integrity through unauthorized update, insert, or delete operations creates risks for data corruption and manipulation that could severely impact business operations and compliance requirements.
Organizations should implement immediate mitigations including network segmentation to isolate Oracle E-Business Suite components from untrusted networks, deployment of web application firewalls to monitor and filter HTTP traffic, and implementation of robust authentication mechanisms. The vulnerability's presence in multiple versions indicates the need for comprehensive patch management strategies and security assessments across all affected Oracle E-Business Suite installations. Additionally, organizations should conduct regular security audits and implement monitoring solutions to detect unauthorized access attempts to telephony interfaces, ensuring that any suspicious network activity is promptly identified and addressed. This vulnerability exemplifies the importance of maintaining current security patches and implementing defense-in-depth strategies to protect critical enterprise applications from exploitation.
