CVE-2026-89124 in HANA
Summary
by MITRE • 10/13/2026
Display Product Catalog Based on Customs Declaration application does not perform sufficient authorization checks within certain functionality, allowing an authenticated low-privileged user to access sensitive information beyond their intended authorization scope. This vulnerability has low impact on confidentiality of the data, with no impact on the integrity and availability of the application.

The identified security flaw represents a classic case of broken object level authorization, where the application fails to adequately verify that an authenticated user possesses the necessary permissions to access specific resources or perform certain actions within the system. Specifically, in the context of displaying product catalogs based on customs declarations, the software logic does not sufficiently restrict data visibility according to the assigned role or privilege level of the requesting entity. This deficiency allows a low-privileged user, who should only have limited access rights, to bypass intended security controls and retrieve sensitive information that falls outside their authorized scope. The vulnerability stems from an inadequate implementation of access control mechanisms at the application layer, where the server relies on client-side inputs or insufficiently validated session attributes rather than enforcing strict server-side authorization checks for every data retrieval request.
From a technical perspective, this issue aligns with CWE-269, which categorizes improper privilege escalation through unauthorized direct object references or flawed access control logic. The attacker exploits this weakness by manipulating parameters such as identifiers in the URL query string or POST body to reference customs declarations belonging to other users or entities they do not own. Because the application does not cross-reference these requested resources against a centralized authorization policy tied to the user's current session, it returns the data without objection. This type of vulnerability is particularly dangerous because it targets the core business logic of multi-tenant applications where data isolation between different organizational units or users is critical for maintaining operational integrity and regulatory compliance.
The impact of this vulnerability is primarily confined to the confidentiality aspect of the security triad, as noted in the initial description. The exposure allows unauthorized parties to view sensitive commercial information contained within customs declarations, such as product details, shipment values, origin countries, and potentially customer contact information depending on the depth of data exposed. While there is no direct impact on system integrity or availability since the attacker cannot modify records or disrupt service operations, the leakage of proprietary business intelligence can lead to significant competitive disadvantages for affected organizations. Furthermore, in industries subject to strict regulatory frameworks like GDPR or HIPAA, such unauthorized access could result in legal penalties and reputational damage due to non-compliance with data protection standards.
In terms of threat modeling, this vulnerability maps directly to the MITRE ATT&CK technique T1078, specifically Valid Accounts used for lateral movement or information gathering within a specific environment. An adversary would leverage these valid but low-privileged credentials to enumerate sensitive assets without triggering typical intrusion detection alerts associated with brute force attacks or credential stuffing. The stealthy nature of exploiting authorization flaws means that traditional perimeter defenses may not detect the activity, making it essential to implement robust monitoring and logging mechanisms focused on access control violations rather than just authentication failures.
To mitigate this vulnerability, developers must enforce strict server-side authorization checks for every endpoint involved in retrieving product catalog data based on customs declarations. This involves implementing a centralized access control model where each request is validated against the user's role-based permissions before any database query or business logic execution occurs. It is crucial to avoid relying solely on client-supplied identifiers and instead use indirect references that map securely to internal resource IDs while verifying ownership at every step. Additionally, adopting principles of least privilege ensures that users only receive the minimum level of access necessary for their job functions. Regular security testing, including automated penetration tests focused on horizontal privilege escalation, should be integrated into the development lifecycle to identify and remediate such flaws before deployment.
