CVE-2026-61340 in MES for Process Manufacturing
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle MES for Process Manufacturing 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 unauthenticated attacker with network access via HTTP to compromise Oracle MES for Process Manufacturing. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle MES for Process Manufacturing, 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 MES for Process Manufacturing accessible data as well as unauthorized update, insert or delete access to some of Oracle MES for Process Manufacturing accessible data. CVSS 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The identified vulnerability resides within the Internal Operations component of Oracle MES for Process Manufacturing, a critical module within the broader 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 allows an unauthenticated attacker to initiate exploitation over standard HTTP network connections without requiring prior credentials or authentication tokens. While the vulnerability is technically located within the Oracle MES for Process Manufacturing application, its impact extends beyond that specific boundary due to potential scope changes in how data and system resources are shared across integrated products within the E-Business Suite environment. This interconnectedness means that compromising this single component can lead to cascading effects on other dependent systems, amplifying the overall risk profile for organizations relying on these integrated manufacturing solutions.
The technical mechanism of exploitation relies heavily on social engineering principles rather than purely automated code execution techniques. Successful compromise requires human interaction from a user who is not the attacker, indicating that this vulnerability likely involves诱骗 users to perform actions such as clicking malicious links or submitting crafted inputs through web interfaces. This characteristic aligns with Common Weakness Enumeration (CWE) categories related to insufficient input validation and potential cross-site scripting or request forgery mechanisms where trusted context is abused. The requirement for user interaction significantly lowers the barrier to entry for attackers but also necessitates a more targeted approach, often involving phishing campaigns or deceptive content designed to trick employees into triggering the vulnerable code paths within the application logic.
From an operational perspective, the consequences of a successful exploit are severe and multifaceted. An attacker who gains access through this vulnerability can achieve unauthorized read access to critical business data stored within the manufacturing execution system. This includes sensitive production metrics, supply chain details, inventory levels, and potentially proprietary process formulas or quality control standards that give competitors an unfair advantage. Furthermore, the integrity of the system is compromised as attackers gain the ability to perform unauthorized updates, inserts, or deletes on accessible data sets. Such modifications can disrupt manufacturing workflows, corrupt financial records tied to production costs, alter inventory counts leading to supply chain discrepancies, and introduce malicious configurations into operational parameters. The combination of high confidentiality impact and moderate integrity impact results in a CVSS 3.1 Base Score of 8.2, reflecting the critical nature of this threat to business continuity and data security.
In terms of attack classification within the MITRE ATT&CK framework, this vulnerability facilitates techniques associated with Initial Access via phishing or valid accounts if user interaction leads to credential harvesting, followed by Data Exfiltration for confidential information retrieval and potentially Impact through data manipulation or destruction. The scope change aspect highlights the importance of understanding system interdependencies; an attacker does not need direct access to every module to cause widespread damage because compromising this internal operations component provides a foothold that can be leveraged against other integrated products within the Oracle E-Business Suite landscape. This lateral movement potential increases the urgency for remediation, as isolating the affected component may no longer contain the threat effectively once initial compromise is achieved.
Mitigation strategies must address both immediate technical fixes and broader security hygiene practices. Organizations running vulnerable versions of Oracle MES for Process Manufacturing should prioritize applying the latest available patches provided by Oracle to close the specific code flaws exploited in this vulnerability. Since human interaction is a prerequisite, robust employee training programs focused on recognizing social engineering attempts are essential complements to technical controls. Implementing strict web application firewalls can help detect and block malicious HTTP requests that attempt to exploit these weaknesses before they reach the application layer. Additionally, enforcing multi-factor authentication for all administrative and privileged accounts reduces the likelihood of credential compromise if phishing efforts succeed in capturing login details. Regular audits of data access logs should be conducted to identify any unauthorized modifications or extractions resulting from past exploitation attempts, ensuring that integrity violations are detected promptly.
