CVE-2024-21032 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-2024-21032 resides within Oracle Complex Maintenance, Repair, and Overhaul component of the Oracle E-Business Suite, specifically within the LOV (List of Values) functionality. This represents a critical security weakness that affects versions 12.2.3 through 12.2.13 of the suite, making it a widespread concern across numerous enterprise deployments. The vulnerability's classification as easily exploitable indicates that attackers can leverage it without requiring specialized tools or extensive technical knowledge, while the requirement for network access via HTTP means that the attack surface extends to any system with web-facing interfaces.
The technical flaw manifests as an authentication bypass mechanism that allows unauthenticated attackers to access sensitive functionality within the maintenance and overhaul systems. This vulnerability operates through a combination of insufficient authorization checks and potentially flawed input validation within the LOV component, which serves as a critical interface for data selection and retrieval processes. The CVSS 3.1 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 the vulnerability can affect additional products beyond the primary target. The vector analysis reveals that while network access is required, the attack complexity is low, meaning that even non-privileged users can potentially exploit this weakness.
The operational impact of this vulnerability extends far beyond the immediate scope of the Complex Maintenance, Repair, and Overhaul system, as indicated by the scope change designation in the CVSS vector. Attackers who successfully exploit this vulnerability can achieve unauthorized update, insert, or delete operations against sensitive maintenance data, potentially compromising the integrity of critical repair schedules, maintenance records, and overhaul procedures. Additionally, the unauthorized read access capability allows attackers to extract subsets of sensitive maintenance data, which could include confidential information about equipment status, repair histories, and operational procedures that are essential for maintaining system integrity and safety protocols. The requirement for human interaction suggests that while the initial exploitation may require some form of social engineering or user engagement, the actual vulnerability can be leveraged without requiring elevated privileges or specialized access rights.
Organizations should implement immediate mitigations including network segmentation to limit access to the affected Oracle E-Business Suite components, deployment of web application firewalls to monitor and filter HTTP traffic, and thorough access control reviews to ensure that only authorized personnel can interact with the vulnerable LOV functionality. The vulnerability aligns with CWE-287 which addresses authentication issues, and may map to ATT&CK techniques involving credential access and privilege escalation through application-level vulnerabilities. Regular patching and vulnerability management processes should be prioritized to address this weakness, while security monitoring should focus on detecting unusual access patterns to maintenance and overhaul data repositories. The scope change aspect of this vulnerability necessitates broader security assessments to identify potential impacts on connected systems that may rely on the compromised maintenance data for operational decision-making.
