CVE-2026-83166 in Customer Interaction History
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Customer Interaction History product of Oracle E-Business Suite (component: Outcome-Result). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Customer Interaction History. While the vulnerability is in Oracle Customer Interaction History, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Customer Interaction History accessible data. CVSS 3.1 Base Score 7.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).

Analysis

The identified vulnerability resides within the Outcome-Result component of Oracle Customer Interaction History, a module integral to Oracle E-Business Suite versions 12.2.3 through 12.2.15. This security flaw represents a significant risk due to its potential for unauthorized data access and its ability to affect products beyond the immediate scope of the vulnerable component. The vulnerability is classified as easily exploitable, requiring only low-privileged credentials and network access via HTTP to initiate an attack vector. This accessibility lowers the barrier for entry significantly, allowing attackers with minimal initial privileges to escalate their influence within the system architecture.
From a technical perspective, the flaw likely stems from insufficient input validation or improper authorization checks within the Outcome-Result processing logic. When an attacker sends specifically crafted requests over HTTP, the application fails to properly verify whether the user has sufficient rights to access specific data sets associated with customer interactions. This failure results in a breakdown of the intended security boundary, permitting the retrieval of sensitive information that should remain restricted to higher-level administrators or authorized personnel only. The reliance on HTTP rather than HTTPS further exacerbates the risk by potentially exposing transmission details if not properly secured at the network layer, although the primary flaw is application-side logic.
The operational impact of this vulnerability is severe, characterized primarily by high-impact confidentiality breaches as indicated by a CVSS 3.1 Base Score of 7.7. Successful exploitation allows an attacker to gain unauthorized access to critical data stored within Oracle Customer Interaction History. In worst-case scenarios, the attacker may achieve complete access to all data accessible through this module, which typically contains sensitive customer interaction records, personal identifiable information, and potentially proprietary business intelligence. The scope change noted in the advisory suggests that compromising this component can lead to lateral movement or privilege escalation affecting other integrated products within the E-Business Suite environment, thereby amplifying the overall risk posture for the organization.
This vulnerability aligns with Common Weakness Enumeration (CWE) categories such as CWE-269: Improper Privilege Management and CWE-862: Missing Authorization. It also maps to MITRE ATT&CK techniques related to Credential Access or Data Exfiltration, specifically where an attacker leverages existing low-level access to harvest sensitive data without triggering immediate detection mechanisms due to the use of legitimate HTTP channels. The lack of user interaction required for exploitation means that automated scanning tools can rapidly identify and exploit this weakness across multiple instances in a networked environment.
Mitigation strategies must focus on both technical remediation and administrative controls. Oracle has released patches addressing this specific flaw, and organizations running affected versions 12.2.3 through 12.2.15 should apply the latest security updates immediately to close the authorization gap within the Outcome-Result component. In addition to patching, it is critical to enforce strict network segmentation policies that limit HTTP access to only necessary administrative interfaces while ensuring all such traffic is encrypted via HTTPS to prevent eavesdropping and man-in-the-middle attacks. Access control lists should be reviewed to ensure that low-privileged accounts do not have unnecessary permissions on customer interaction data modules. Regular vulnerability assessments and penetration testing focused on authentication bypasses are recommended to detect similar misconfigurations before they can be exploited by malicious actors.
