CVE-2024-41979 in SmartClient modules Opcenter QL Home
Summary
by MITRE • 08/12/2025
A vulnerability has been identified in SmartClient modules Opcenter QL Home (SC) (All versions >= V13.2 = V13.2 = V13.2 < V2506). The affected application does not enforce mandatory authorization on some functionality level at server side. This could allow an authenticated attacker to gain complete access of the application.

The vulnerability identified in CVE-2024-41979 affects the SmartClient modules Opcenter QL Home application, specifically targeting versions from V13.2 through V2506. This represents a critical authorization bypass flaw that undermines the fundamental security controls of the system. The issue stems from insufficient server-side validation mechanisms that fail to properly enforce mandatory authorization checks on specific functionality levels within the application's architecture. Such a weakness creates a pathway for malicious actors who have already established authentication credentials to escalate their privileges and achieve complete control over the application environment.
The technical flaw manifests as a failure in the application's mandatory access control implementation, where server-side authorization enforcement mechanisms are either absent or improperly configured. This allows authenticated users to bypass intended security boundaries and access functionality that should be restricted based on their assigned permissions. The vulnerability operates at the application layer where proper authorization controls should be enforced, and the absence of these controls creates a direct attack vector for privilege escalation. From a cybersecurity perspective, this represents a severe deviation from the principle of least privilege and mandatory access control principles that are fundamental to secure application design.
The operational impact of this vulnerability is profound as it enables authenticated attackers to gain complete access to the application, potentially leading to data breaches, system compromise, and unauthorized administrative actions. An attacker could exploit this weakness to manipulate application data, modify user permissions, access sensitive information, or even take control of the entire application infrastructure. The scope of potential damage extends beyond simple unauthorized access to include full system compromise, making this vulnerability particularly dangerous for organizations that rely on the Opcenter QL Home platform for critical business operations. The impact is exacerbated by the fact that the vulnerability affects multiple versions within the specified range, suggesting a systemic issue rather than an isolated incident.
Organizations should implement immediate mitigations including strengthening server-side authorization controls, conducting comprehensive access control reviews, and implementing additional monitoring for unauthorized access attempts. The vulnerability aligns with CWE-285 which addresses improper authorization issues in software systems, and represents a clear violation of the ATT&CK technique T1078 which covers valid accounts and legitimate credentials for unauthorized access. Security teams should deploy enhanced logging and monitoring capabilities to detect suspicious access patterns and ensure that all functionality level access controls are properly enforced. Additionally, organizations should consider implementing network segmentation and least privilege access models to minimize the potential impact of such vulnerabilities in their environments.
