CVE-2024-21030 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-2024-21030 resides within Oracle Complex Maintenance, Repair, and Overhaul component of the Oracle E-Business Suite, specifically affecting the List of Values (LOV) functionality. This security flaw impacts versions 12.2.3 through 12.2.13, representing a significant attack surface within enterprise maintenance management systems. The vulnerability's classification as easily exploitable indicates that attackers can leverage network-based HTTP access without requiring authentication credentials, making it particularly dangerous for organizations operating these critical business applications. The CVSS 3.1 base score of 6.1 reflects moderate severity with impacts to both confidentiality and integrity, while the vector analysis reveals network accessibility with low attack complexity and no required privileges, though human interaction is necessary for successful exploitation.
The technical implementation of this vulnerability stems from insufficient input validation and access control mechanisms within the LOV component, which processes user requests for data retrieval and display. When users interact with maintenance workflows, the system fails to properly validate or sanitize input parameters passed to the LOV functionality, potentially allowing malicious actors to manipulate query parameters and gain unauthorized access to sensitive maintenance data. The scope change aspect of this vulnerability indicates that while the primary target is the Complex Maintenance, Repair, and Overhaul module, successful exploitation can extend impacts to other integrated Oracle E-Business Suite components, creating cascading security implications across the enterprise platform. This interconnected nature of Oracle applications means that compromise of one module can potentially provide attackers with broader access to related systems and data repositories.
The operational impact of CVE-2024-21030 extends beyond simple data access violations, as attackers can achieve unauthorized update, insert, and delete operations against maintenance records, potentially corrupting critical operational data or creating false maintenance entries that could lead to equipment failures or safety incidents. Additionally, the unauthorized read access capability allows attackers to extract sensitive information about maintenance schedules, equipment status, and repair histories, which could be valuable for competitive intelligence or further targeting of the organization's infrastructure. The requirement for human interaction suggests that attackers might need to诱导 users to perform specific actions, potentially through social engineering or phishing campaigns that target maintenance personnel or system administrators. This human factor component increases the attack surface and requires additional security awareness training for end users within the organization.
Organizations should implement immediate mitigations including network-level restrictions to limit HTTP access to the affected Oracle E-Business Suite components, deployment of web application firewalls to monitor and filter suspicious requests, and comprehensive access control reviews to ensure proper least-privilege principles are enforced. The vulnerability's classification under CWE-20 (Improper Input Validation) and its alignment with ATT&CK technique T1190 (Exploit Public-Facing Application) highlights the need for both defensive measures and monitoring capabilities. Security teams should also conduct thorough vulnerability assessments to identify any additional unpatched components within the Oracle E-Business Suite ecosystem and implement regular security updates to prevent similar vulnerabilities from emerging in other modules. Given the scope change implications, organizations should consider broader security posture improvements including network segmentation, enhanced logging and monitoring, and regular penetration testing to identify potential attack vectors that could exploit similar weaknesses in interconnected systems.
