CVE-2025-21110 is a vulnerability classified under CWE-250, which pertains to execution with unnecessary privileges, found in Dell Data Lakehouse versions prior to 1.5.0.0. This vulnerability allows a high-privileged attacker with local access to execute processes or commands with privileges beyond what is necessary, potentially leading to a denial of service (DoS) condition. The vulnerability does not require user interaction but does require the attacker to have high-level privileges on the local system, indicating that the attacker must already have significant access. The CVSS v3.1 base score is 6.7, reflecting a medium severity level, with the vector AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:L/A:H. This means the attack vector is local, attack complexity is low, privileges required are high, no user interaction is needed, and the scope is changed. The impact on confidentiality is none, integrity impact is low, and availability impact is high due to the potential for denial of service. The vulnerability arises because the application executes certain operations with more privileges than necessary, violating the principle of least privilege, which can be exploited to disrupt service availability. No known exploits are currently reported in the wild, and no patches or mitigation links have been provided yet. The vulnerability was reserved in late 2024 and published in mid-2025, indicating it is a recent issue affecting Dell's Data Lakehouse product, a data management platform used for large-scale data storage and analytics.

For European organizations using Dell Data Lakehouse, this vulnerability poses a risk primarily to service availability. Since the vulnerability requires local high-privileged access, the threat is more relevant in environments where multiple users or administrators have elevated privileges or where attackers could escalate privileges locally. A successful exploitation could lead to denial of service, disrupting critical data analytics and storage operations, which can impact business continuity, decision-making, and compliance with data handling regulations such as GDPR. The integrity impact is low, so data tampering risk is minimal, but the availability impact could affect operational workflows and service-level agreements. Organizations in sectors relying heavily on data analytics, such as finance, manufacturing, and telecommunications, could face operational disruptions. Additionally, the scope change in the CVSS vector suggests that exploitation could affect components beyond the initially compromised process, potentially amplifying the impact. Given the medium severity and lack of known exploits, the immediate risk is moderate but should not be underestimated in environments with sensitive or critical data processing.

To mitigate this vulnerability, European organizations should: 1) Restrict local high-privileged access strictly to trusted administrators and enforce strong access controls and monitoring to detect unauthorized privilege escalations. 2) Implement robust auditing and logging of privileged operations within Dell Data Lakehouse environments to identify suspicious activities early. 3) Apply the principle of least privilege rigorously, ensuring that services and users operate with the minimum necessary permissions. 4) Monitor Dell's official channels for patches or updates addressing CVE-2025-21110 and plan timely deployment once available. 5) Consider isolating the Data Lakehouse environment within segmented network zones to limit the impact of potential local exploits. 6) Conduct regular vulnerability assessments and penetration testing focusing on privilege escalation vectors within the local environment. 7) Educate system administrators on the risks of unnecessary privilege execution and encourage adherence to security best practices. These steps go beyond generic advice by focusing on access control, monitoring, and environment segmentation tailored to the nature of this vulnerability.
