CVE-2025-46608 is an improper access control vulnerability classified under CWE-284, affecting Dell Data Lakehouse versions prior to 1.6.0.0. This vulnerability allows an attacker who already has high-level privileges and remote access to escalate their privileges further, potentially gaining unauthorized administrative control over the system. The flaw arises from insufficient enforcement of access controls within the Data Lakehouse platform, which manages large-scale data storage and analytics workloads. Because the vulnerability permits elevation of privileges without requiring user interaction, it can be exploited remotely by an attacker who has compromised or legitimately holds a high-privilege account. The CVSS v3.1 score of 9.1 reflects the critical nature of this vulnerability, with attack vector being network-based (AV:N), low attack complexity (AC:L), requiring high privileges (PR:H), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H) with scope changed (S:C). Exploitation could lead to unauthorized data access, modification, or disruption of services, severely impacting organizational operations and data security. Although no known exploits have been reported in the wild yet, the critical severity and potential impact necessitate urgent remediation. Dell recommends upgrading to version 1.6.0.0 or later, which addresses this access control weakness. Organizations should also review their privilege management and network access policies to limit exposure.

For European organizations, the impact of CVE-2025-46608 could be severe, especially for those relying on Dell Data Lakehouse for data analytics, storage, and processing. Successful exploitation could lead to unauthorized access to sensitive customer and business data, manipulation or deletion of critical datasets, and disruption of data services. This can result in significant operational downtime, regulatory non-compliance (e.g., GDPR violations due to data breaches), reputational damage, and financial losses. Given the critical nature of the vulnerability, attackers could leverage it to move laterally within networks, escalate privileges further, and compromise additional systems. Organizations in sectors such as finance, healthcare, telecommunications, and government, which often use large-scale data lake solutions, are particularly at risk. The remote exploitability and lack of required user interaction increase the likelihood of targeted attacks or insider threats exploiting this vulnerability.

European organizations should immediately upgrade Dell Data Lakehouse to version 1.6.0.0 or later as recommended by Dell to remediate this vulnerability. In addition, organizations should implement strict network segmentation to isolate Data Lakehouse environments and restrict remote access to trusted administrators only. Conduct a thorough audit of existing high-privilege accounts and enforce the principle of least privilege to minimize the number of users with elevated access. Enable and monitor detailed logging and alerting for unusual access patterns or privilege escalations within the Data Lakehouse environment. Employ multi-factor authentication (MFA) for all administrative access to reduce the risk of credential compromise. Regularly review and update access control policies and conduct penetration testing focused on privilege escalation vectors. Finally, maintain an incident response plan that includes procedures for rapid containment and remediation of access control breaches.
