CVE-2024-21034 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-2024-21034 resides within Oracle Complex Maintenance, Repair, and Overhaul component of the Oracle E-Business Suite, specifically affecting the List of Values (LOV) functionality. This flaw represents a significant security weakness in Oracle's enterprise resource planning ecosystem, where the LOV component serves as a critical interface for data selection and validation within maintenance operations. The vulnerability impacts versions 12.2.3 through 12.2.13, indicating a substantial attack surface across multiple releases of the software suite that organizations have deployed in their maintenance and repair operations.
The technical nature of this vulnerability manifests as an easily exploitable weakness that allows unauthenticated attackers to compromise the system through HTTP network access without requiring any prior authentication credentials. This characteristic places the vulnerability in the category of network-based attacks that can be executed remotely, making it particularly dangerous for organizations with exposed web interfaces. The attack vector specifically targets the LOV functionality, which typically provides users with predefined lists of valid values for data entry fields, but in this case, the validation mechanisms have been compromised. The vulnerability's classification as CVSS 3.1 Base Score 6.1 reflects its moderate severity, with confidentiality and integrity impacts rated as low, though the scope change aspect indicates broader implications beyond the targeted component.
The operational impact of this vulnerability extends beyond the immediate compromise of the Complex Maintenance, Repair, and Overhaul functionality. Successful exploitation can result in unauthorized modification of data through update, insert, or delete operations against sensitive maintenance records, while also enabling unauthorized read access to portions of the system's data. This dual impact on both confidentiality and integrity creates a significant risk for organizations relying on accurate maintenance records for operational planning, inventory management, and compliance reporting. The requirement for human interaction from a person other than the attacker suggests that social engineering or user manipulation may be necessary to complete the attack, though this does not eliminate the automated nature of the initial exploitation. The scope change aspect indicates that the attack may affect additional Oracle products within the E-Business Suite ecosystem, potentially creating cascading impacts across multiple maintenance and repair processes.
Organizations should implement immediate mitigations including network segmentation to limit access to the vulnerable web interfaces, deployment of web application firewalls to monitor and filter HTTP requests, and the application of Oracle's official security patches as soon as they become available. The vulnerability aligns with CWE-284 (Improper Access Control) and may map to ATT&CK techniques involving initial access through web application attacks and privilege escalation through data manipulation. Given the potential for scope change impacts, comprehensive monitoring should extend beyond the immediate affected component to include related maintenance and repair modules, while regular vulnerability assessments should be conducted to identify similar weaknesses in other Oracle E-Business Suite components. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) emphasizes the low attack complexity and lack of privilege requirements, while the human interaction requirement suggests that user education and awareness programs should be enhanced to prevent successful exploitation attempts.
