CVE-2024-21027 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 exists within Oracle E-Business Suite's Complex Maintenance, Repair, and Overhaul component, specifically in the List of Values (LOV) functionality. The flaw affects versions 12.2.3 through 12.2.13, representing a significant attack surface for organizations utilizing this enterprise resource planning solution. The vulnerability is classified as easily exploitable, meaning that malicious actors can leverage it without requiring specialized skills or extensive preparation. The attack vector operates through HTTP network access, eliminating the need for authentication or privileged credentials during the initial exploitation phase. This characteristic makes the vulnerability particularly dangerous as it can be targeted by automated scanning tools and opportunistic attackers.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the LOV component. When processing user requests through HTTP protocols, the system fails to properly authenticate or authorize access to sensitive data operations. The vulnerability requires human interaction from an unsuspecting user, suggesting that social engineering or phishing techniques might be employed to trigger the malicious payload. However, the actual exploitation mechanism operates through the web interface, where unauthenticated requests can manipulate the LOV functionality to access restricted data. This represents a classic case of insufficient authorization checks that violates fundamental security principles and creates pathways for unauthorized data manipulation.
The operational impact of this vulnerability extends beyond the immediate scope of Complex Maintenance, Repair, and Overhaul, as indicated by the CVSS scope change designation. Attackers can achieve unauthorized update, insert, or delete operations on sensitive maintenance data, potentially compromising the integrity of critical repair schedules, maintenance records, and operational procedures. Additionally, the vulnerability enables unauthorized read access to portions of the system's data, allowing attackers to extract sensitive information about maintenance operations, equipment status, and repair histories. The CVSS base score of 6.1 reflects the moderate severity of the impact, with confidentiality and integrity being the primary affected areas. The vector assessment shows network accessibility with low attack complexity, no privilege requirements, and requiring user interaction, indicating that the vulnerability could be leveraged by attackers with minimal technical expertise.
Organizations should implement immediate mitigations including network-level firewalls to restrict HTTP access to the affected components, ensuring that only authorized personnel can reach the vulnerable interfaces. Regular security updates and patches from Oracle should be applied as soon as they become available to address the root cause of the vulnerability. Access control measures must be strengthened through proper authentication mechanisms and role-based access controls to limit the scope of potential damage. The vulnerability aligns with CWE-284, which describes improper access control issues, and maps to ATT&CK technique T1078 for valid accounts and T1566 for social engineering. Monitoring and logging of HTTP requests to the affected LOV components should be enhanced to detect anomalous access patterns that might indicate exploitation attempts. Security awareness training for end users should be implemented to reduce the risk of successful social engineering attacks that require human interaction for initial exploitation.
