CVE-2024-21046 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-2024-21046 affects Oracle Complex Maintenance, Repair, and Overhaul within the Oracle E-Business Suite ecosystem, specifically within the List of Values (LOV) component. This issue represents a significant security weakness that impacts versions 12.2.3 through 12.2.13 of the software suite. The vulnerability resides in the authentication mechanisms of the LOV functionality, creating an attack surface that can be exploited by unauthenticated remote adversaries. The affected component operates within the broader Oracle E-Business Suite framework, which typically serves as a comprehensive enterprise resource planning solution for organizations managing complex maintenance operations. The vulnerability's presence in this critical business application component creates substantial risk for organizations relying on these systems for their operational maintenance workflows.
The technical flaw manifests as an insufficient access control mechanism within the LOV functionality that allows unauthorized network access via HTTP protocols. This vulnerability requires minimal attacker privileges and can be exploited from remote locations without authentication requirements. The attack vector operates through standard HTTP communication channels, making it particularly dangerous as it can be executed using common network reconnaissance tools and techniques. The vulnerability's classification as easily exploitable indicates that the attack mechanisms are straightforward and well-documented, reducing the barrier for potential attackers. The requirement for human interaction from a person other than the attacker suggests that while the initial exploitation may be automated, some form of user involvement or system interaction is necessary for full exploitation to occur.
The operational impact of this vulnerability extends beyond the immediate scope of the Complex Maintenance, Repair, and Overhaul component, creating what is termed a scope change in the attack surface. Successful exploitation can result in unauthorized modification of data through update, insert, and delete operations on sensitive maintenance records and related information. Additionally, attackers can gain unauthorized read access to portions of the system's data that should remain protected, potentially exposing maintenance schedules, repair histories, and overhaul documentation. The CVSS 3.1 base score of 6.1 reflects the moderate severity of the impact, with confidentiality and integrity being the primary compromised aspects. The vector indicates network accessibility with low attack complexity and no privilege requirements, while the scope change component suggests that the attack could affect additional products within the Oracle E-Business Suite environment.
Organizations should prioritize immediate mitigation efforts including applying Oracle's security patches and updates to affected versions, implementing network segmentation to limit access to the vulnerable components, and conducting thorough vulnerability assessments of their entire Oracle E-Business Suite deployment. The vulnerability aligns with CWE-284, which addresses improper access control issues, and may relate to ATT&CK techniques involving privilege escalation and credential access through network-based attacks. Security teams should also consider implementing additional monitoring and logging controls specifically targeting HTTP access patterns to the LOV components, as well as establishing network access controls to restrict unauthorized access to these vulnerable functionalities. The scope change aspect of this vulnerability necessitates comprehensive assessment of how the attack might propagate across interconnected Oracle E-Business Suite modules to ensure complete protection of the enterprise environment.
