CVE-2024-21033 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-2024-21033 affects Oracle Complex Maintenance, Repair, and Overhaul component within the Oracle E-Business Suite ecosystem. This particular flaw resides in the List of Values (LOV) functionality, which serves as a critical user interface element for data selection and navigation within maintenance operations. The vulnerability impacts a broad range of supported versions from 12.2.3 through 12.2.13, indicating a substantial attack surface across multiple releases of the enterprise suite. The CVSS 3.1 scoring of 6.1 reflects a medium severity classification with specific emphasis on confidentiality and integrity impacts, while the vector analysis reveals network-based exploitation with low attack complexity and no privilege requirements.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the LOV component. An unauthenticated attacker can exploit this weakness through HTTP network connections without requiring prior authentication credentials or elevated privileges. However, successful exploitation necessitates human interaction from a legitimate user, suggesting that the vulnerability likely involves user-facing interfaces or interactive elements that require user confirmation or action before malicious payloads can be executed. This requirement for human interaction typically reduces the automated exploitation potential but does not eliminate the threat entirely, particularly in environments where users may be subjected to social engineering or phishing attacks.
The operational impact of CVE-2024-21033 extends beyond the immediate scope of the Complex Maintenance, Repair, and Overhaul component, as indicated by the CVSS scope change vector element. This suggests that successful exploitation could potentially affect additional Oracle products within the E-Business Suite environment, creating cascading security implications across the enterprise application landscape. Attackers who successfully exploit this vulnerability can achieve unauthorized modifications to data through update, insert, or delete operations against sensitive maintenance and repair records. Additionally, the vulnerability permits unauthorized read access to subsets of data within the affected system, potentially exposing confidential maintenance schedules, repair histories, inventory information, and other operational data that could be valuable for competitive intelligence or further exploitation attempts.
From a cybersecurity framework perspective, this vulnerability aligns with CWE-20 (Improper Input Validation) and CWE-287 (Improper Authentication) categories, reflecting the core issues of inadequate validation controls and potential authentication bypass mechanisms. The attack pattern corresponds to techniques described in the MITRE ATT&CK framework under initial access and privilege escalation domains, particularly focusing on web application exploitation methods and credential harvesting. Organizations should implement comprehensive network segmentation to limit access to Oracle E-Business Suite components, deploy web application firewalls to monitor and filter HTTP traffic, and establish robust monitoring procedures to detect anomalous access patterns. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in related components, while user education programs can help reduce the risk of social engineering attacks that may leverage this vulnerability's requirement for human interaction. The affected scope necessitates coordinated patch management across all impacted versions, with particular attention to ensuring that updates do not introduce compatibility issues with existing maintenance workflows or data integrity requirements within the complex enterprise environment.
