CVE-2024-21029 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-2024-21029 affects Oracle Complex Maintenance, Repair, and Overhaul within the Oracle E-Business Suite ecosystem, specifically within the List of Values (LOV) component. This security flaw represents a significant concern for organizations utilizing Oracle EBS platforms, as it resides in a core maintenance functionality that governs how system data is presented and managed. The affected versions span from 12.2.3 through 12.2.13, indicating a substantial attack surface across multiple releases of the enterprise suite. The vulnerability's classification as easily exploitable suggests that attackers can leverage network-based HTTP access without requiring authentication credentials, making it particularly dangerous for organizations with exposed web services.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the LOV component of the maintenance system. Attackers can exploit this weakness by crafting malicious HTTP requests that manipulate the LOV functionality to gain unauthorized access to system data. The requirement for human interaction from someone other than the attacker indicates that social engineering or user-specific actions may be necessary to trigger the vulnerability, though the underlying technical flaw remains accessible to unauthorized parties. This attack vector specifically targets the integrity and confidentiality aspects of the system, allowing for unauthorized modifications to data as well as read access to sensitive information within the maintenance and overhaul processes.
The operational impact of this vulnerability extends beyond the immediate scope of Oracle Complex Maintenance, Repair, and Overhaul due to the scope change aspect mentioned in the vulnerability description. Organizations may experience significant disruption as attackers can potentially compromise data integrity within maintenance records, work orders, and overhaul procedures that are critical to operational continuity. The confidentiality implications are equally concerning as unauthorized read access could expose sensitive maintenance data, including equipment specifications, repair histories, and overhaul schedules that might contain proprietary or strategic business information. The CVSS 3.1 score of 6.1 indicates a medium severity classification that reflects the potential for data compromise without system availability disruption, though the scope change element suggests broader implications across interconnected systems.
Organizations should implement immediate mitigations including network segmentation to limit access to Oracle EBS components, enforcing strict firewall rules to restrict HTTP access to authorized administrative networks, and implementing robust monitoring solutions to detect anomalous access patterns. The vulnerability aligns with CWE-284 (Improper Access Control) and CWE-20 (Improper Input Validation) categories, indicating fundamental flaws in access control mechanisms and data validation processes. From an ATT&CK framework perspective, this vulnerability maps to techniques involving credential access and privilege escalation through web application exploitation. Regular patch management procedures should be prioritized to ensure timely deployment of Oracle's security patches, while additional security controls such as web application firewalls and intrusion detection systems can provide layered protection against exploitation attempts. Organizations should also conduct thorough security assessments of their EBS environments to identify and remediate similar vulnerabilities in other components that may be susceptible to similar attack vectors.
