CVE-2026-83141 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. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Field Service. While the vulnerability is in Oracle Field Service, 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 Field Service 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).

The identified vulnerability resides within the Internal Operations component of Oracle Field Service, a critical module within the broader Oracle E-Business Suite ecosystem. This flaw affects supported software versions ranging from 12.2.3 through 12.2.15, indicating that it is present in multiple releases and has likely persisted across several update cycles without adequate remediation. The core technical nature of this vulnerability allows for exploitation by an attacker who possesses only low-level privileges yet maintains network access via the HTTP protocol. This specific configuration highlights a significant failure in privilege separation and input validation within the application logic, enabling unauthorized entities to interact with sensitive internal functions that should be restricted to higher-privileged administrative accounts or isolated from direct external exposure.
The operational impact of this vulnerability is severe due to its potential for scope change, meaning that while the technical flaw originates in Oracle Field Service, successful exploitation can lead to a compromise of additional products within the E-Business Suite environment. This lateral movement capability transforms what might otherwise be an isolated data leak into a broader enterprise security incident. The primary consequence of exploiting this weakness is unauthorized access to critical business data and potentially complete access to all data accessible by Oracle Field Service. Given that field service applications often handle sensitive customer information, operational logistics, and proprietary business processes, such unrestricted data exposure poses substantial risks to confidentiality and regulatory compliance.
From a classification perspective, this vulnerability aligns with Common Weakness Enumeration categories related to broken access control and insufficient privilege checks, specifically reflecting CWE-269 Improper Privilege Management or CWE-862 Missing Authorization depending on the exact mechanism of exploitation. The attack vector is classified as Network-based with Low Attack Complexity, requiring no user interaction but necessitating low privileges initially. This profile corresponds closely to MITRE ATT&CK techniques involving Initial Access and Credential Access, where attackers leverage existing valid credentials to escalate their influence within the system architecture. The CVSS 3.1 base score of 7.7 reflects a High severity rating driven primarily by high confidentiality impacts, while integrity and availability remain unaffected in this specific vector description.
To mitigate this risk, organizations must prioritize applying the latest security patches provided by Oracle for all affected versions between 12.2.3 and 12.2.15 immediately upon verification of their environment's version status. In addition to patching, it is essential to review network segmentation strategies to ensure that HTTP access to internal operations components is restricted to trusted administrative networks rather than exposed to general user or external traffic zones. Implementing strict role-based access controls and auditing existing low-privileged accounts for excessive permissions can further reduce the attack surface. Continuous monitoring of authentication logs for anomalous patterns associated with privilege escalation attempts will also aid in early detection of exploitation activities targeting this specific weakness.
