CVE-2024-21036 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-2024-21036 resides within Oracle Complex Maintenance, Repair, and Overhaul component of the Oracle E-Business Suite, specifically within the List of Values (LOV) functionality. This flaw represents a significant security weakness that affects Oracle E-Business Suite versions 12.2.3 through 12.2.13, making it accessible to attackers without requiring authentication credentials. The vulnerability's classification as easily exploitable indicates that malicious actors can leverage network-based HTTP access to compromise the targeted system, presenting a substantial risk to organizations utilizing these legacy versions of Oracle's enterprise suite.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the LOV component, which allows attackers to manipulate data through crafted HTTP requests. The CVSS 3.1 scoring of 6.1 reflects the moderate severity of the threat, with confidentiality and integrity impacts rated as low, though the potential for unauthorized data modification and read access cannot be understated. The vulnerability requires human interaction from a user other than the attacker, suggesting that social engineering or targeted phishing campaigns might be necessary to initiate the attack vector, though the underlying technical flaw remains exploitable. The scope change aspect of this vulnerability indicates that while the primary target is the Complex Maintenance, Repair, and Overhaul component, successful exploitation could potentially impact additional Oracle E-Business Suite products, amplifying the overall security impact.
The operational impact of CVE-2024-21036 extends beyond simple data access violations, as attackers can potentially execute unauthorized update, insert, or delete operations against sensitive maintenance and repair data within the Oracle E-Business Suite environment. This capability compromises the integrity of maintenance records, repair schedules, and overhaul documentation that organizations depend upon for operational continuity. Additionally, the unauthorized read access to subset data means that attackers could potentially extract sensitive information about maintenance activities, repair costs, and overhaul procedures, which could be valuable for competitive intelligence or further exploitation attempts. The vulnerability's network accessibility and lack of authentication requirements make it particularly dangerous in environments where the Oracle E-Business Suite is exposed to external networks without proper perimeter controls.
Organizations should implement immediate mitigations including applying the relevant Oracle critical patch updates, restricting network access to the affected components, and implementing network segmentation to limit exposure. The vulnerability aligns with CWE-284 (Improper Access Control) and may be related to ATT&CK technique T1213.002 (Data from Information Repositories) through the unauthorized access to data repositories within the Oracle E-Business Suite. Security teams should also consider implementing network monitoring to detect suspicious HTTP traffic patterns and establish baseline behaviors for the LOV component to identify potential exploitation attempts. Given the scope change potential, organizations should conduct comprehensive assessments of their entire Oracle E-Business Suite environment to identify any cascading effects from successful exploitation of this vulnerability across interconnected modules.
