CVE-2024-21016 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-2024-21016 resides within Oracle E-Business Suite's Complex Maintenance, Repair, and Overhaul component, specifically affecting the List of Values (LOV) functionality. This represents a significant security weakness in Oracle's enterprise resource planning software suite that impacts organizations utilizing versions 12.2.3 through 12.2.13. 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 with exposed web services. The CVSS score of 6.1 reflects moderate severity but underscores the potential for data compromise through unauthorized modifications and read access to sensitive operational data.
The technical flaw manifests through a lack of proper access controls within the LOV component, allowing unauthenticated attackers to manipulate maintenance and overhaul data through HTTP requests. This vulnerability operates at the application layer and requires minimal technical expertise to exploit, as it does not demand privileged credentials or complex attack vectors. The attack requires human interaction from an individual other than the attacker, suggesting that the exploitation may involve social engineering elements or targeted user actions that could be initiated by the attacker. The scope change aspect indicates that while the primary target is the Complex Maintenance, Repair, and Overhaul module, the impact extends to potentially affecting additional Oracle E-Business Suite components, amplifying the overall risk to the organization's operational integrity.
The operational impact of this vulnerability extends beyond simple data access violations to include unauthorized modification capabilities that could severely disrupt maintenance operations and compromise the integrity of critical repair and overhaul data. Attackers could potentially insert false maintenance records, modify existing entries, or delete essential data that maintains equipment reliability and operational safety. The confidentiality aspect allows unauthorized read access to a subset of accessible data, which could include sensitive maintenance schedules, equipment specifications, or repair histories that might be valuable for competitive intelligence or operational disruption. This vulnerability aligns with CWE-284 (Improper Access Control) and maps to ATT&CK technique T1078 (Valid Accounts) and T1566 (Phishing) through the human interaction requirement, while also representing a privilege escalation pathway through the LOV component's inadequate access controls.
Organizations should immediately implement network segmentation to limit access to Oracle E-Business Suite web interfaces, particularly the Complex Maintenance, Repair, and Overhaul components. Patch management should be prioritized to ensure all affected versions receive the appropriate Oracle security updates, with particular attention to the LOV functionality within the maintenance suite. Network monitoring should be enhanced to detect unusual HTTP traffic patterns targeting the affected modules, while access controls should be reviewed and strengthened to prevent unauthorized modifications. The vulnerability's CVSS vector indicates that while no system modification or deletion capabilities are directly available, the combination of read and write access to maintenance data creates substantial operational risk that could affect equipment reliability and safety protocols. Regular security assessments should be conducted to verify that the implemented mitigations effectively prevent exploitation of this vulnerability across all affected Oracle E-Business Suite installations.
