CVE-2024-21031 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-2024-21031 affects Oracle Complex Maintenance, Repair, and Overhaul within the Oracle E-Business Suite ecosystem, specifically within the List of Values (LOV) component. This security flaw exists in versions 12.2.3 through 12.2.13, representing a significant risk to organizations utilizing these legacy 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 environments where such systems are exposed to external networks. The attack vector requires minimal sophistication and can be executed by unauthenticated adversaries who can directly access the affected application layer.
The technical nature of this vulnerability stems from inadequate input validation and access control mechanisms within the LOV functionality of the maintenance suite. When exploited, the vulnerability enables attackers to perform unauthorized operations including data modification, insertion, and deletion within the affected system's data repositories. Additionally, the flaw permits unauthorized read access to specific subsets of data that should otherwise be protected. The CVSS 3.1 scoring of 6.1 reflects the moderate severity of impacts across both confidentiality and integrity dimensions, with the attack requiring human interaction from users other than the attacker, suggesting a social engineering component or user involvement in the exploitation process. The scope change aspect of this vulnerability indicates that while the primary target is the Complex Maintenance, Repair, and Overhaul component, the attack may extend impacts to other interconnected Oracle E-Business Suite modules, potentially creating cascading security consequences.
Organizations impacted by this vulnerability face substantial operational risks including potential data breaches, unauthorized system modifications, and compromised integrity of maintenance workflows. The requirement for human interaction suggests that attackers may need to manipulate users into performing specific actions that trigger the vulnerability, potentially through phishing campaigns or other social engineering techniques. This attack pattern aligns with common tactics used in targeted exploitation campaigns where user engagement is necessary to complete the attack chain. The vulnerability's presence in a maintenance and overhaul system is particularly concerning as these components often contain critical operational data related to asset management, maintenance schedules, and repair records that are essential for business continuity and safety compliance.
Security mitigations for CVE-2024-21031 should prioritize immediate patch application from Oracle, as this represents the most effective defense against the identified vulnerability. Organizations should implement network segmentation to limit direct access to the affected Oracle E-Business Suite components and consider deploying web application firewalls to monitor and filter HTTP traffic to these systems. Access controls should be reviewed and strengthened to ensure that only authorized personnel can interact with the LOV components, while additional monitoring should be implemented to detect unusual access patterns or data modification activities. The vulnerability's classification under CWE categories related to insufficient input validation and inadequate access controls highlights the importance of implementing comprehensive security measures that address both the specific flaw and broader security posture weaknesses. Organizations should also consider implementing principle of least privilege access models and regular security assessments to identify and remediate similar vulnerabilities across their Oracle E-Business Suite deployments, as this type of vulnerability often indicates systemic security gaps that may affect other components within the same application suite.
