CVE-2017-3401 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-2017-3401 represents a critical security flaw within Oracle Advanced Outbound Telephony component of the Oracle E-Business Suite ecosystem. This particular weakness resides in the User Interface subcomponent of the telephony system, which serves as a crucial interface for managing outbound telephony operations within enterprise environments. The vulnerability affects multiple version lines including 12.1.1 through 12.2.6, indicating a widespread impact across several generations of the Oracle E-Business Suite platform. The flaw manifests as an easily exploitable condition that allows unauthenticated attackers to compromise the telephony system through standard HTTP network connections, bypassing traditional authentication mechanisms that should normally protect such sensitive enterprise communications infrastructure.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the Oracle Advanced Outbound Telephony User Interface component. Attackers can leverage this weakness through HTTP network access without requiring prior authentication credentials, making the attack vector particularly dangerous in environments where network exposure is inevitable. The vulnerability's classification as easily exploitable indicates that the attack requires minimal technical skill or resources to execute successfully, while the need for human interaction from individuals other than the attacker suggests that social engineering or user-specific actions may be required to complete the exploitation process. This characteristic places additional risk on organizations where user behavior and awareness levels vary significantly across different operational roles.
The operational impact of this vulnerability extends far beyond the immediate telephony component, as successful exploitation can result in unauthorized access to critical data and complete access to all data accessible through Oracle Advanced Outbound Telephony. The potential for unauthorized update, insert, or delete operations against sensitive telephony data represents a severe threat to both data confidentiality and integrity. Organizations utilizing this telephony system typically handle sensitive customer information, communication logs, and business-critical telephony data that could be compromised through this vulnerability. The CVSS v3.0 Base Score of 8.2 reflects the high severity of the impact, with particular emphasis on confidentiality and integrity implications that align with CWE-284 (Improper Access Control) and CWE-20 (Improper Input Validation) categories. The vulnerability's potential to impact additional products within the Oracle E-Business Suite ecosystem indicates a cascading effect that could compromise the entire enterprise communication infrastructure.
Mitigation strategies for CVE-2017-3401 should prioritize immediate implementation of network-level controls including firewalls and access control lists to restrict HTTP access to the vulnerable telephony component. Organizations should implement strong authentication mechanisms and ensure that the Oracle Advanced Outbound Telephony system is properly isolated within secure network segments. Regular security updates and patches from Oracle should be applied immediately upon availability, as the vulnerability affects multiple supported versions requiring comprehensive remediation across affected systems. Network monitoring should be enhanced to detect unusual access patterns or unauthorized attempts to interact with the telephony interface. The vulnerability's characteristics align with ATT&CK techniques focusing on Initial Access through Web Application Exploitation and Persistence through unauthorized data access, making comprehensive security monitoring essential for early detection of potential exploitation attempts. Additionally, user education programs should be implemented to reduce the risk of social engineering attacks that may be required to complete exploitation, particularly given the human interaction requirement for successful compromise of this vulnerability.
