CVE-2020-14670 in Advanced Outbound Telephony
Summary
by MITRE
Vulnerability in the Oracle Advanced Outbound Telephony product of Oracle E-Business Suite (component: Settings). Supported versions that are affected are 12.1.1-12.1.3 and 12.2.3-12.2.9. 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 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2020-14670 resides within Oracle Advanced Outbound Telephony component of the Oracle E-Business Suite, specifically within the Settings module. This security flaw affects Oracle E-Business Suite versions 12.1.1 through 12.1.3 and 12.2.3 through 12.2.9, representing a significant attack surface for organizations utilizing these legacy systems. The vulnerability manifests as an easily exploitable weakness that can be leveraged by unauthenticated attackers who possess network access via HTTP protocols, making it particularly dangerous in environments where such network exposure exists.
The technical nature of this vulnerability stems from inadequate authentication mechanisms within the Advanced Outbound Telephony settings interface, allowing attackers to bypass normal access controls without requiring valid credentials. This flaw operates at the application layer and specifically targets the configuration and management interfaces of the telephony component. The vulnerability's classification as requiring human interaction indicates that while the initial exploitation may not be fully automated, it can be initiated through user actions that are often unavoidable in business environments where legitimate users interact with the system. The CVSS 3.1 score of 8.2 reflects the high severity of this issue, with a base score indicating high confidentiality impact and low integrity impact, suggesting that while attackers can access sensitive data, the primary concern lies in unauthorized data disclosure rather than modification.
The operational impact of this vulnerability extends beyond the immediate Advanced Outbound Telephony component to potentially affect additional Oracle products within the E-Business Suite ecosystem. This cascading effect demonstrates how vulnerabilities in one component can create broader security implications across interconnected systems. Successful exploitation can lead to unauthorized access to critical business data, including sensitive telephony configurations, call logs, and potentially customer information managed through the telephony system. The vulnerability also allows for unauthorized update, insert, or delete operations on accessible data, providing attackers with both read and write capabilities that can result in data corruption or manipulation. Organizations utilizing affected versions face significant risk of data breaches, regulatory compliance violations, and potential operational disruption due to the comprehensive nature of the access granted to unauthorized parties.
Mitigation strategies for CVE-2020-14670 should prioritize immediate patch deployment from Oracle, as this represents the most effective defense against exploitation. Organizations should implement network segmentation to limit access to the affected components, particularly restricting HTTP access to authorized administrative networks only. The principle of least privilege should be enforced by ensuring that only necessary personnel have access to the telephony settings interface, and additional authentication controls should be implemented where possible. Network monitoring should be enhanced to detect unusual access patterns or attempts to access telephony configuration interfaces. This vulnerability aligns with CWE-287, which addresses authentication failures, and maps to ATT&CK techniques related to credential access and privilege escalation. Organizations should also conduct thorough vulnerability assessments to identify any additional unpatched systems within their Oracle E-Business Suite environment that may be similarly affected, as this vulnerability could potentially be leveraged as a foothold for broader attacks within the enterprise infrastructure.
