CVE-2026-83092 in Field Service
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Field Service product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Field Service. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Field Service accessible data as well as unauthorized access to critical data or complete access to all Oracle Field Service accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Field Service. CVSS 3.1 Base Score 7.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L).

The identified vulnerability resides within the Internal Operations component of Oracle Field Service, a critical module in the Oracle E-Business Suite ecosystem. This security flaw affects supported software versions ranging from 12.2.3 through 12.2.15. The nature of this defect is characterized by its complexity; it requires specific conditions to be met for exploitation, making it difficult for attackers to leverage successfully without precise knowledge of the system's internal state or configuration. Despite this high barrier to entry, the potential impact of a successful exploit is severe, affecting multiple pillars of information security including confidentiality, integrity, and availability. The vulnerability allows an attacker who has already gained low-level privileged access within the network perimeter to compromise the Oracle Field Service application via standard HTTP protocols. This indicates that while external direct exploitation from the internet may be hindered by authentication requirements or network segmentation, internal lateral movement by a compromised user account can lead to significant system-wide consequences.
From an operational perspective, the impact of this vulnerability is multifaceted and substantial. A successful attack enables unauthorized creation, deletion, or modification of critical data within the Oracle Field Service environment. This directly compromises the integrity of business operations that rely on accurate field service records, scheduling, and resource allocation. Furthermore, the attacker gains the ability to access sensitive information that should be restricted by role-based access controls, leading to a breach of confidentiality for customer data, operational metrics, or proprietary business intelligence contained within the system. The vulnerability also introduces risks related to availability, as it can cause a partial denial of service condition. This means that while the entire system may not go completely offline, specific functionalities could become unresponsive or degraded, disrupting field operations and potentially causing financial loss due to delayed services or operational inefficiencies.
The technical classification of this flaw aligns with common vulnerability categories such as Broken Access Control, where an application fails to properly restrict actions based on user privileges. In the context of industry standards like CWE (Common Weakness Enumeration), this likely corresponds to weaknesses related to improper authorization checks or insecure direct object references that allow a low-privileged user to perform administrative-level functions. The attack vector is classified as Network with High complexity, indicating that while the vulnerability is reachable over HTTP, it requires specific contextual conditions to be exploited successfully. This aligns with MITRE ATT&CK techniques involving Privilege Escalation or Data Exfiltration via compromised application interfaces. The CVSS 3.1 base score of 7.1 reflects a High severity rating, driven by the high impact on confidentiality and integrity alongside moderate impact on availability.
Mitigation strategies for this vulnerability must focus on both immediate remediation and long-term architectural improvements. Oracle has likely released patches or updates to address these specific flaws in versions beyond 12.2.15; therefore, applying the latest security patches is the primary defense mechanism. Organizations should prioritize upgrading their Oracle E-Business Suite environments to supported versions that include fixes for this internal operations flaw. In addition to patching, implementing strict network segmentation can limit the attack surface by ensuring that only authorized systems and users have HTTP access to the Oracle Field Service components. Role-based access control policies must be reviewed to ensure that low-privileged accounts do not possess unnecessary permissions that could be exploited in conjunction with this vulnerability. Regular security audits and penetration testing should also be conducted to identify any misconfigurations or additional weaknesses within the internal operations module, ensuring a defense-in-depth approach against potential exploitation attempts by malicious insiders or attackers who have achieved initial foothold access.
