CVE-2020-14671 in Advanced Outbound Telephony
Summary
by MITRE
Vulnerability in the Oracle Advanced Outbound Telephony product of Oracle E-Business Suite (component: User Interface). Supported versions that are affected are 12.1.1-12.1.3. 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-2020-14671 resides within Oracle Advanced Outbound Telephony, a component of the Oracle E-Business Suite ecosystem. This particular weakness manifests in the User Interface portion of the Advanced Outbound Telephony product, affecting versions 12.1.1 through 12.1.3. The vulnerability represents a significant security gap that enables unauthenticated attackers to compromise the targeted system through network-based HTTP access. The attack vector specifically leverages HTTP protocols, making it accessible to threat actors who can exploit this weakness without requiring prior authentication credentials or privileged access to the system.
The technical flaw constitutes a critical authentication bypass vulnerability that operates through the user interface component of Oracle Advanced Outbound Telephony. This weakness allows attackers to gain unauthorized access to sensitive data and perform modifications to the system's information repository. The vulnerability's classification as easily exploitable indicates that the attack mechanisms are straightforward and do not require specialized knowledge or complex attack chains. However, the requirement for human interaction from individuals other than the attacker introduces a social engineering element that makes the attack more sophisticated in execution. This human interaction component suggests that the vulnerability might be exploited through techniques such as phishing or social engineering campaigns that trick users into performing actions that facilitate the attack.
The operational impact of this vulnerability extends beyond the immediate scope of Oracle Advanced Outbound Telephony, potentially affecting additional Oracle products within the E-Business Suite environment. This cascading effect demonstrates the interconnected nature of Oracle's enterprise applications and highlights how a single vulnerability in one component can compromise the broader enterprise security posture. Successful exploitation can result in unauthorized access to critical data repositories, potentially exposing sensitive business information, customer data, or financial records. The vulnerability's potential for complete access to all accessible data within the Advanced Outbound Telephony system represents a severe threat to data confidentiality and integrity.
The CVSS 3.1 score of 8.2 reflects the severity of this vulnerability, with high impact on confidentiality and low impact on integrity. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) indicates that the attack requires network access with low complexity, no prior privileges, and human interaction that could significantly impact additional products. This scoring system aligns with CWE-287, which addresses authentication issues, and demonstrates characteristics consistent with ATT&CK technique T1212, focusing on exploitation of remote services. The vulnerability's potential for unauthorized update, insert, or delete operations further amplifies the risk, as it allows attackers to modify or corrupt data within the system, potentially causing operational disruptions or data integrity violations. Organizations should implement immediate mitigation strategies including network segmentation, access controls, and monitoring for suspicious HTTP traffic patterns to protect against exploitation of this vulnerability.
The exploitation of this vulnerability requires attackers to leverage human interaction, which suggests that security awareness training becomes critical in preventing successful attacks. This aspect of the vulnerability places additional emphasis on user education and awareness programs that can help identify and prevent social engineering attempts. The vulnerability's impact on data confidentiality and integrity makes it particularly concerning for organizations handling sensitive information within their Oracle E-Business Suite deployments. The interconnected nature of Oracle's products means that compromise of one component can potentially lead to broader system infiltration, making this vulnerability particularly dangerous in enterprise environments where multiple Oracle applications operate in concert. Organizations should prioritize patch management and security updates to address this vulnerability, as well as implement robust monitoring solutions to detect and respond to exploitation attempts.
