CVE-2024-21037 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-2024-21037 affects Oracle Complex Maintenance, Repair, and Overhaul component within the Oracle E-Business Suite ecosystem. This represents a significant security weakness that exists in versions 12.2.3 through 12.2.13 of the software. The affected component specifically relates to the List of Values (LOV) functionality, which serves as a critical interface element for data selection and navigation within the maintenance management processes. The vulnerability's classification as easily exploitable indicates that attackers can leverage it without requiring specialized skills or privileged access, making it particularly dangerous in production environments where such systems handle sensitive operational data.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the LOV implementation. Attackers can exploit this weakness through unauthenticated HTTP network connections, eliminating the need for valid credentials or prior system access. The attack requires human interaction from a legitimate user, suggesting that the exploitation might occur through social engineering or targeted phishing campaigns that trick users into interacting with malicious payloads. This human interaction requirement, while providing a potential defense layer, also indicates that the vulnerability can be weaponized through user manipulation rather than purely technical means.
The operational impact of this vulnerability extends beyond the immediate scope of the Complex Maintenance, Repair, and Overhaul component, as indicated by the CVSS scope change vector. This means that successful exploitation can potentially affect additional Oracle E-Business Suite products that share underlying infrastructure or data access mechanisms. The confidentiality and integrity impacts are rated at low severity levels, suggesting that attackers can gain unauthorized access to read and modify data within the affected system. Specifically, the vulnerability allows unauthorized update, insert, or delete operations on certain data elements, while also enabling read access to portions of the system's data repository. This dual impact capability creates substantial risk for organizations relying on the system for critical maintenance operations and asset management.
The CVSS 3.1 base score of 6.1 places this vulnerability in the medium severity category, reflecting the combination of network accessibility, low attack complexity, and the potential for significant data compromise. The vector analysis reveals that the attack requires network access (AV:N), has low attack complexity (AC:L), involves no privilege requirements (PR:N), but necessitates user interaction (UI:R) and can cause scope changes (S:C). Organizations should consider this vulnerability in the context of the MITRE ATT&CK framework, particularly within the reconnaissance and credential access phases where attackers might leverage such weaknesses to establish persistent access or escalate privileges. The vulnerability aligns with CWE-284 (Improper Access Control) and CWE-352 (Cross-Site Request Forgery) categories, highlighting the fundamental access control flaws that enable unauthorized data manipulation and read access.
Mitigation strategies should prioritize immediate patch deployment for affected Oracle E-Business Suite versions, as Oracle typically releases security patches to address such vulnerabilities. Network segmentation and firewall rules can provide additional protection by restricting direct HTTP access to the affected components. Implementing proper input validation controls and access control mechanisms within the LOV functionality can help prevent exploitation even if other security measures fail. Organizations should also consider implementing user awareness training to reduce the risk of social engineering attacks that could trigger the vulnerability through human interaction. Regular security assessments and penetration testing of Oracle E-Business Suite environments can help identify similar weaknesses that might exist within the broader system architecture. The vulnerability's characteristics suggest that organizations should also review their incident response procedures to ensure rapid detection and remediation of potential exploitation attempts.
