CVE-2024-21028 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).

This vulnerability resides within Oracle E-Business Suite's Complex Maintenance, Repair, and Overhaul component, specifically within the List of Values (LOV) functionality. The affected versions span from 12.2.3 through 12.2.13, representing a significant portion of the Oracle EBS ecosystem that organizations rely upon for critical maintenance operations. 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 interfaces.
The technical flaw manifests as a security weakness in the LOV component's handling of user input and access controls, allowing unauthorized individuals to manipulate data within the maintenance system. This represents a classic privilege escalation vulnerability where an attacker can gain unauthorized access to modify or delete sensitive maintenance records and data. The CVSS 3.1 score of 6.1 reflects the moderate severity, with confidentiality and integrity impacts rated as low, though the scope change aspect indicates potential broader system compromise. The attack vector requires network access via HTTP and necessitates human interaction from a legitimate user, suggesting that the vulnerability may be triggered through social engineering or targeted phishing campaigns that prompt users to interact with malicious payloads.
The operational impact of this vulnerability extends beyond the immediate maintenance system, as indicated by the scope change element in the CVSS vector. Attackers who successfully exploit this weakness can potentially access sensitive maintenance data, including repair records, overhaul schedules, and equipment configurations that are critical to operational continuity. The unauthorized update, insert, or delete capabilities could lead to significant disruptions in maintenance planning and execution, while read access to subset data might expose proprietary maintenance procedures or sensitive operational information. Organizations using Oracle EBS for critical infrastructure maintenance may face substantial operational risks including delayed maintenance schedules, compromised safety protocols, and potential regulatory compliance violations.
Mitigation strategies should prioritize immediate patching of affected Oracle EBS versions through official Oracle security updates and patches. Network segmentation and firewall rules should be implemented to restrict unnecessary HTTP access to the LOV component, while monitoring systems should be enhanced to detect anomalous access patterns. Organizations should also consider implementing additional authentication controls and access logging for the affected component, as outlined in CWE-287 for improper authentication vulnerabilities. The ATT&CK framework's T1190 technique for Exploit Public-Facing Application should be considered when developing incident response procedures, given that this vulnerability enables attackers to compromise systems through publicly accessible web interfaces. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other Oracle EBS components and ensure comprehensive protection against similar attack vectors.
