CVE-2024-21045 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 CVE-2024-21045 represents a critical security flaw within Oracle Complex Maintenance, Repair, and Overhaul component of the Oracle E-Business Suite ecosystem. This vulnerability specifically affects versions 12.2.3 through 12.2.13, making it a widespread concern across multiple releases of the enterprise suite. The flaw resides within the List of Values (LOV) functionality, which serves as a crucial interface component for data selection and retrieval within maintenance operations. The vulnerability's classification as easily exploitable indicates that attackers can leverage it without requiring specialized tools or extensive technical knowledge, making it particularly dangerous in production environments where such systems are typically exposed to network traffic.
The technical implementation of this vulnerability stems from insufficient input validation and access control mechanisms within the LOV component. Attackers can exploit this weakness through unauthenticated HTTP network access, bypassing traditional authentication barriers that would normally protect sensitive maintenance data. The CVSS 3.1 scoring 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 the vulnerability can affect additional products beyond the targeted component. This scope expansion typically occurs due to shared architectural elements or common data access patterns between different Oracle E-Business Suite modules, creating cascading security implications that extend far beyond the initially identified vulnerable component.
The operational impact of this vulnerability manifests through unauthorized data manipulation and access capabilities that can significantly compromise maintenance operations and related business processes. Successful exploitation enables attackers to perform unauthorized update, insert, or delete operations against maintenance data, potentially corrupting critical repair schedules, maintenance records, and overhaul planning information. Additionally, the vulnerability permits unauthorized read access to sensitive subsets of maintenance-related data, which could include confidential maintenance procedures, equipment specifications, or repair cost information. The requirement for human interaction from someone other than the attacker suggests that the exploitation may involve social engineering components or require specific user actions that facilitate the attack vector, though this does not reduce the overall security risk.
Organizations should implement immediate mitigations to address this vulnerability, beginning with network-level restrictions that limit access to the affected Oracle E-Business Suite components. The implementation of web application firewalls and intrusion detection systems can help monitor and block suspicious HTTP traffic patterns associated with exploitation attempts. Patch management protocols should be prioritized to ensure that affected systems receive the appropriate Oracle security patches as soon as they become available. Security teams must also conduct comprehensive audits of maintenance data access controls and implement principle of least privilege configurations to minimize potential damage from successful exploitation attempts. The vulnerability's classification under CWE 79 (Cross-site Scripting) and potential ATT&CK framework mappings to T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS) highlights the need for multi-layered defensive strategies that address both network and application-level security concerns. Organizations should also consider implementing additional logging and monitoring capabilities specifically designed to detect unauthorized access attempts to maintenance-related data repositories, as the scope change aspect of this vulnerability indicates that impact may extend beyond the immediate component to related business applications within the Oracle E-Business Suite ecosystem.
