CVE-2024-21026 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-2024-21026 resides within Oracle Complex Maintenance, Repair, and Overhaul component of the Oracle E-Business Suite, specifically affecting the List of Values (LOV) functionality. This issue 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 in environments where such systems are exposed to external networks. The attack vector requires human interaction from users other than the attacker, suggesting that the exploitation typically occurs through social engineering or user engagement with malicious content.
The technical flaw manifests in the LOV component's insufficient input validation and access control mechanisms, allowing unauthorized individuals to manipulate data within the maintenance management system. This weakness enables attackers to achieve unauthorized update, insert, or delete operations on sensitive maintenance data, while also providing unauthorized read access to specific subsets of the system's information. The CVSS 3.1 base score of 6.1 reflects the moderate severity of the vulnerability, with confidentiality and integrity impacts rated as low, though the scope change aspect indicates potential for broader system compromise. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) demonstrates that network-based attacks with low complexity and no privilege requirements can successfully exploit this weakness, while the scope change component suggests that the attack may affect additional products beyond the primary target.
The operational impact of this vulnerability extends beyond the immediate maintenance system, potentially compromising related enterprise applications and data repositories. Organizations utilizing Oracle E-Business Suite for maintenance operations face significant risks including data integrity breaches, unauthorized modifications to maintenance schedules, and potential disruption of critical operational workflows. The scope change aspect of the vulnerability means that successful exploitation could impact additional Oracle products within the suite, creating cascading effects throughout the enterprise's maintenance and repair processes. This vulnerability particularly affects industries relying on complex maintenance management, such as aviation, manufacturing, and energy sectors where maintenance records and operational data integrity are critical.
Security practitioners should implement immediate mitigations including network segmentation to limit access to the affected system, deployment of web application firewalls to monitor and filter HTTP traffic, and comprehensive user access reviews to ensure proper privilege controls. The vulnerability aligns with CWE-284 (Improper Access Control) and potentially CWE-352 (Cross-Site Request Forgery) depending on the specific exploitation method. From an ATT&CK framework perspective, this vulnerability maps to techniques involving privilege escalation and credential access through network-based attacks. Organizations should also consider implementing additional monitoring for unusual data access patterns and ensure regular patching of Oracle E-Business Suite components to prevent exploitation. The vulnerability's requirement for human interaction suggests that user education and awareness programs should be enhanced to reduce the risk of successful social engineering attacks targeting this weakness.
