CVE-2026-83435 in Bills of Material
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Bills of Material product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.13-12.2.15. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Bills of Material. While the vulnerability is in Oracle Bills of Material, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Bills of Material accessible data as well as unauthorized access to critical data or complete access to all Oracle Bills of Material accessible data. CVSS 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N).

The identified vulnerability resides within the Oracle Bills of Material component, specifically under the Internal Operations module of Oracle E-Business Suite. This security flaw affects supported software versions ranging from 12.2.13 through 12.2.15. The nature of this defect is characterized as a complex exploitation vector that requires specific conditions to be met for successful compromise. Although the vulnerability is technically located within the Bills of Material subsystem, its impact extends beyond this single module due to the interconnected architecture of the E-Business Suite ecosystem. Consequently, an attack targeting this flaw can lead to a scope change where additional products and data stores become compromised, amplifying the overall risk profile for organizations relying on these integrated business processes.
From a technical perspective, the vulnerability allows an attacker with low privileges and network access via HTTP to execute unauthorized operations against critical system resources. The requirement for low-privileged access indicates that pre-authentication or basic user-level credentials are sufficient to trigger the exploit, while the high complexity of exploitation suggests that automated tools may not easily detect or leverage this flaw without precise payload construction. The attack vector is remote and network-based, meaning it can be initiated from across a corporate intranet or potentially over the internet if HTTP services are exposed. The absence of user interaction requirements further lowers the barrier for entry, allowing an attacker to target the system passively once initial access conditions are satisfied.
The operational impact of this vulnerability is severe, primarily affecting data confidentiality and integrity while leaving availability intact according to the provided CVSS metrics. Successful exploitation enables unauthorized creation, deletion, or modification of critical business data within Oracle Bills of Material. This includes potentially altering bill structures, component lists, and manufacturing instructions which are vital for production planning and inventory management. Furthermore, attackers gain complete access to all data accessible by the compromised user account, leading to significant confidentiality breaches. In an enterprise environment where bills of material dictate supply chain logistics and cost accounting, such integrity violations can result in substantial financial loss, operational disruption, and regulatory non-compliance.
This vulnerability aligns with Common Weakness Enumeration categories related to improper access control and insecure direct object references, as it allows a lower-privileged user to perform actions typically reserved for higher-level administrators or system processes. In the context of the MITRE ATT&CK framework, this behavior corresponds to techniques involving unauthorized data manipulation and potential lateral movement within the application layer. The high scope change noted in the CVSS vector underscores the risk of privilege escalation through functional dependencies between modules, a pattern often seen in complex ERP systems where shared database schemas or API endpoints are exploited to pivot from one module to another.
Mitigation strategies must prioritize immediate patching by applying the latest security updates provided by Oracle for versions 12.2.13 through 12.2.15. Organizations should verify their current version and apply relevant patches as soon as they become available in the Critical Patch Update cycle. In addition to software remediation, network segmentation is recommended to restrict HTTP access to internal operations modules from untrusted networks. Implementing strict role-based access controls ensures that users are granted only the minimum privileges necessary for their job functions, thereby reducing the attack surface even if a vulnerability like this exists. Regular auditing of user permissions and monitoring for anomalous data modification patterns can also help detect potential exploitation attempts before significant damage occurs.
