CVE-2024-21023 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-2024-21023 affects Oracle Complex Maintenance, Repair, and Overhaul component within the Oracle E-Business Suite ecosystem, specifically impacting versions 12.2.3 through 12.2.13. This represents a critical security weakness that exploits the LOV (List of Values) functionality within the maintenance suite, creating a pathway for unauthorized access to sensitive operational data. The vulnerability's classification as easily exploitable indicates that attackers can leverage standard network-based HTTP protocols without requiring authentication credentials, making it particularly dangerous in environments where network exposure is inevitable.
The technical flaw manifests through an insufficient access control mechanism within the LOV component, which fails to properly validate user permissions before granting data access. This weakness enables attackers to manipulate HTTP requests and potentially gain unauthorized access to maintenance records, repair logs, and overhaul documentation that should remain restricted to authorized personnel. The vulnerability's CVSS score of 6.1 reflects the balance between the ease of exploitation and the potential impact on data integrity and confidentiality, with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N indicating network-based access with low complexity, no prior privileges required, and a scope change that can affect additional products beyond the primary target. The requirement for human interaction suggests that while the initial attack vector is automated, some form of user action may be necessary to complete the exploitation process.
The operational impact of this vulnerability extends beyond the immediate maintenance and repair data, as successful exploitation can result in unauthorized modification of critical operational records and selective data reading from the system. This compromise directly affects the integrity of maintenance schedules, repair histories, and overhaul procedures that are essential for operational continuity and regulatory compliance. Organizations utilizing Oracle E-Business Suite for complex maintenance operations face significant risks including potential safety hazards from tampered maintenance records, financial losses from unauthorized data modifications, and compliance violations that could result in regulatory penalties. The scope change aspect of this vulnerability means that attackers may be able to impact additional Oracle products within the suite, potentially creating cascading effects across the enterprise's operational technology infrastructure.
Security mitigations for CVE-2024-21023 should prioritize immediate patch application from Oracle to address the root cause of the access control weakness. Organizations should implement network segmentation to limit access to Oracle E-Business Suite components, deploy web application firewalls to monitor and filter HTTP traffic, and establish comprehensive network monitoring to detect anomalous access patterns. The implementation of principle of least privilege access controls, regular security assessments of the LOV component, and enhanced user authentication mechanisms should be prioritized. Additionally, organizations should conduct thorough vulnerability scanning to identify any additional components that may be susceptible to similar access control flaws, as this vulnerability demonstrates the potential for scope expansion that could impact the broader Oracle E-Business Suite ecosystem. The vulnerability aligns with CWE-284, which addresses improper access control, and represents a potential vector for ATT&CK technique T1213.002, covering data from information repositories, making it a significant concern for enterprise security postures and compliance frameworks.
