CVE-2024-21038 in Complex Maintenance, Repair, and Overhaul
Summary
by MITRE • 04/17/2024
Vulnerability in the Oracle Complex Maintenance, Repair, and Overhaul product of Oracle E-Business Suite (component: LOV). Supported versions that are affected are 12.2.3-12.2.13. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Complex Maintenance, Repair, and Overhaul. Successful attacks require human interaction from a person other than the attacker and 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 update, insert or delete access to some of Oracle Complex Maintenance, Repair, and Overhaul accessible data as well as unauthorized read access to a subset of Oracle Complex Maintenance, Repair, and Overhaul accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2024-21038 resides within Oracle Complex Maintenance, Repair, and Overhaul component of the Oracle E-Business Suite ecosystem, specifically affecting the List of Values (LOV) functionality. This represents a critical security weakness that operates within the broader Oracle E-Business Suite framework, which serves as a comprehensive enterprise resource planning solution for organizations managing complex maintenance operations. The affected versions span from 12.2.3 through 12.2.13, indicating a substantial attack surface across multiple releases of this maintenance-oriented product suite. The vulnerability's classification as easily exploitable suggests that attackers require minimal technical expertise to leverage this weakness, making it particularly concerning for enterprise environments where such systems handle sensitive operational data.
The technical flaw manifests through an insufficient authentication mechanism within the LOV component, allowing unauthenticated attackers to access vulnerable functionality via standard HTTP network connections. This vulnerability operates at the application layer and requires network access to exploit, meaning that remote attackers can potentially compromise the system without requiring valid credentials. The attack vector specifically targets the Oracle Complex Maintenance, Repair, and Overhaul component but demonstrates the potential for scope creep that can impact additional Oracle products within the same ecosystem. The vulnerability's CVSS 3.1 base score of 6.1 indicates a medium severity level, though the combination of confidentiality and integrity impacts creates significant risk for organizations relying on this maintenance management system. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) reveals that network-based attacks are possible with low access complexity, no prior privileges required, and that human interaction is necessary for successful exploitation, while the scope change component suggests broader impact potential.
The operational impact of this vulnerability extends beyond simple data access, enabling unauthorized modification of critical maintenance records and potentially allowing attackers to insert malicious data into the system. This capability directly violates the principles of data integrity and confidentiality that organizations depend upon for maintaining accurate maintenance records and operational procedures. The vulnerability allows for unauthorized read access to subsets of accessible data, which could include sensitive information about maintenance schedules, equipment status, repair histories, and operational procedures. Such access could enable attackers to gain intelligence about organizational maintenance practices and potentially identify additional attack vectors or vulnerabilities within the broader Oracle E-Business Suite environment. The requirement for human interaction suggests that attackers might need to trick users into performing specific actions, potentially through social engineering tactics or by exploiting user trust in legitimate system interfaces.
Organizations should implement immediate mitigations including network segmentation to limit access to the vulnerable Oracle E-Business Suite components, applying the latest Oracle security patches and updates, and implementing robust network monitoring to detect anomalous access patterns. The vulnerability's classification as a scope change risk means that organizations should conduct comprehensive assessments of their entire Oracle E-Business Suite deployment to identify potential cascading impacts. Security teams should also implement strict access controls and authentication mechanisms for any interfaces that might be vulnerable, particularly those related to maintenance and repair data management. The ATT&CK framework would categorize this vulnerability under initial access and privilege escalation techniques, with potential for lateral movement within the Oracle ecosystem. Organizations should also consider implementing database activity monitoring and audit logging to track unauthorized access attempts and maintain compliance with industry standards such as those outlined in the CWE taxonomy for authentication and access control weaknesses. Regular security assessments and vulnerability scanning should be conducted to identify similar vulnerabilities across the broader Oracle E-Business Suite deployment and ensure comprehensive protection against similar threats.
