CVE-2026-83425

Remote Data Exposure and Partial Denial of Service via HTTP in Oracle Complex Maintenance

Published Sep 15, 2026 CVSS 3.1 · 8.5 High EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle Complex Maintenance, Repair and Overhaul product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.12-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Complex Maintenance, Repair and Overhaul. While the vulnerability is in Oracle Complex Maintenance, Repair and Overhaul, 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 Complex Maintenance, Repair and Overhaul accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Complex Maintenance, Repair and Overhaul. CVSS 3.1 Base Score 8.5 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L).

Analysis

Technical impact

A flaw in Oracle Complex Maintenance, Repair and Overhaul allows an attacker with low privileges to reach the system over HTTP, read confidential information, obtain full access to all exposed data, and trigger a partial denial of service. The weakness results in a high confidentiality impact and a low availability impact as documented by the CVSS Base Score of 8.5.

Affected Systems

The vulnerability applies to Oracle E‑Business Suite instances of the Complex Maintenance, Repair and Overhaul component, specifically supported releases 12.2.12 through 12.2.15. The affected portion is the Internal Operations module, with the potential to extend across other Oracle products due to the scope change flag in the CVSS vector.

Risk and Exploitability

EPSS indicates a below‑1 % probability of exploitation, and the vulnerability is not listed in CISA’s KEV catalog, yet the high CVSS score signals a serious risk. Attackers can launch the exploit remotely from any network host capable of reaching the service, requiring only low privileges to initiate the breach. If successful, the attacker can compromise data confidentiality completely and disrupt service availability to a partial degree, impacting business operations.
