CVE-2024-21039 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-2024-21039 resides within Oracle Complex Maintenance, Repair, and Overhaul component of the Oracle E-Business Suite ecosystem, specifically affecting the List of Values (LOV) functionality. This security flaw impacts versions 12.2.3 through 12.2.13, representing a significant exposure across a substantial portion of the Oracle EBS product line. 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 the Oracle EBS components are accessible over unsecured networks or exposed to external traffic.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the LOV component, which allows unauthorized users to manipulate or retrieve data through crafted HTTP requests. The CVSS score of 6.1 reflects the moderate severity of the issue, with confidentiality and integrity impacts rated as low, though the scope change aspect indicates that successful exploitation could affect additional Oracle products beyond the immediate target. The vulnerability requires human interaction from a legitimate user other than the attacker, suggesting that social engineering or targeted phishing campaigns might be necessary to initiate the attack vector, though the underlying flaw remains exploitable without authentication.
From an operational perspective, the successful exploitation of this vulnerability could result in unauthorized modification of critical maintenance data, including the ability to insert, delete, or update information within the maintenance and overhaul systems. Additionally, attackers could gain read access to sensitive data subsets within the Oracle Complex Maintenance, Repair, and Overhaul environment, potentially exposing confidential maintenance schedules, repair histories, or overhaul specifications. The impact extends beyond the immediate component to potentially affect related Oracle EBS modules, creating cascading security implications throughout the enterprise's maintenance management infrastructure. This vulnerability aligns with CWE-284 (Improper Access Control) and represents a significant concern for organizations maintaining critical infrastructure maintenance records.
Organizations should implement immediate mitigations including network segmentation to restrict access to Oracle EBS components, deployment of web application firewalls to monitor and filter HTTP traffic, and enforcement of strong access controls through Oracle's built-in security mechanisms. The recommended approach involves applying Oracle's security patches as soon as they become available, while simultaneously reviewing and strengthening network access controls to limit exposure to unauthorized users. Security monitoring should focus on unusual access patterns, particularly around LOV component interactions, and organizations should conduct comprehensive vulnerability assessments to identify additional attack surfaces that might be affected by the scope change aspect of this vulnerability. The ATT&CK framework categorizes this as a privilege escalation or persistence technique, with potential for lateral movement within the Oracle EBS environment once initial access is achieved, making proactive defense measures crucial for maintaining operational integrity and data security.
