CVE-2026-62518
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle Production Scheduling 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 Production Scheduling. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Production Scheduling accessible data as well as unauthorized read access to a subset of Oracle Production Scheduling accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Production Scheduling. CVSS 3.1 Base Score 7.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L).

This vulnerability resides within Oracle Production Scheduling, a component of the Oracle E-Business Suite that operates under the Internal Operations framework. The affected versions span from 12.2.3 through 12.2.15, indicating a substantial release range where this security flaw persists. The vulnerability's classification as easily exploitable suggests that attackers can leverage relatively simple attack vectors to compromise the system. The attack surface is accessible via HTTP network connections, which means that even remote attackers without physical access to the internal network can potentially exploit this weakness.
The technical flaw manifests as insufficient access controls within the production scheduling module, allowing authenticated users with low privileges to perform unauthorized operations against the underlying data systems. This represents a critical authorization bypass vulnerability that enables attackers to manipulate or extract sensitive information from the Oracle Production Scheduling environment. The CVSS 3.1 base score of 7.6 reflects the severity of impact across confidentiality, integrity, and availability dimensions, with the vector indicating network accessibility (AV:N), low attack complexity (AC:L), and low privilege requirements (PR:L) for successful exploitation.
The operational impact of this vulnerability extends beyond simple data compromise to include potential service disruption through partial denial of service conditions. Attackers can potentially create, delete, or modify critical production scheduling data, which could severely disrupt manufacturing operations and supply chain management processes that depend on accurate scheduling information. Additionally, the unauthorized read access to subsets of data means that sensitive operational information could be extracted, potentially revealing strategic business intelligence or proprietary process details that adversaries could exploit for competitive advantage or further attacks.
Organizations should implement immediate mitigations including network segmentation to limit access to the Oracle Production Scheduling component, enforce strict authentication controls, and apply the latest security patches released by Oracle. The vulnerability aligns with CWE-284 (Improper Access Control) in the Common Weakness Enumeration catalog, which specifically addresses insufficient access control mechanisms that allow unauthorized users to access resources they should not be permitted to access. From an ATT&CK framework perspective, this vulnerability corresponds to techniques such as T1078 (Valid Accounts) and T1566 (Phishing) for initial access, followed by T1046 (Network Service Scanning) and T1562.001 (Disable or Modify Tools) for exploitation and persistence within the environment.
Security teams should conduct comprehensive vulnerability assessments to identify all systems running affected Oracle E-Business Suite versions and implement network monitoring to detect unauthorized access attempts. The partial denial of service capability requires attention to ensure business continuity, particularly in manufacturing environments where production scheduling directly impacts operational efficiency. Regular security audits and privilege reviews are essential to maintain proper access controls and prevent unauthorized users from escalating privileges within the system. Organizations should also consider implementing additional layers of security such as web application firewalls and intrusion detection systems to monitor for exploitation attempts against known vulnerabilities in Oracle applications.
