CVE-2025-30476 is a medium-severity vulnerability identified in Dell PowerScale InsightIQ version 5.2. The vulnerability is classified under CWE-400, which pertains to uncontrolled resource consumption, commonly known as a denial-of-service (DoS) condition. InsightIQ is a monitoring and analytics tool used to manage Dell PowerScale storage systems, providing performance metrics and operational insights. The vulnerability allows an unauthenticated attacker with remote network access to exploit the system by triggering excessive resource consumption. This could lead to a denial of service, where legitimate users are unable to access the InsightIQ service or experience significant degradation in performance. The CVSS v3.1 score is 5.3, reflecting a medium severity level, with the vector indicating that no privileges or user interaction are required (AV:N/AC:L/PR:N/UI:N), and the impact is limited to availability (A:L) without affecting confidentiality or integrity. No known exploits are currently reported in the wild, and no patches have been linked yet. However, the presence of this vulnerability in a critical monitoring tool could impact the operational visibility and management of PowerScale storage environments if exploited.

For European organizations using Dell PowerScale storage solutions with InsightIQ 5.2, this vulnerability poses a risk of service disruption in their storage monitoring infrastructure. While the vulnerability does not directly compromise data confidentiality or integrity, denial of service on InsightIQ can hinder the ability to monitor storage health and performance, potentially delaying detection of other critical issues or failures. This can impact sectors with high data availability requirements such as finance, healthcare, telecommunications, and public administration. Organizations relying on InsightIQ for proactive storage management may face operational inefficiencies and increased risk of storage system outages if the monitoring tool becomes unavailable. Given the unauthenticated nature of the exploit, attackers could launch DoS attacks remotely without needing credentials, increasing the threat surface. The impact is particularly significant in environments where InsightIQ is exposed to less restricted network segments or the internet, increasing the likelihood of exploitation attempts.

European organizations should immediately assess their deployment of Dell PowerScale InsightIQ to determine if version 5.2 is in use. Until an official patch is released, the following specific mitigations are recommended: 1) Restrict network access to the InsightIQ management interface by implementing strict firewall rules or network segmentation to limit access only to trusted administrative hosts. 2) Monitor network traffic and system resource usage on InsightIQ servers for unusual spikes that may indicate exploitation attempts. 3) Employ rate limiting or intrusion prevention systems (IPS) to detect and block anomalous traffic patterns targeting InsightIQ. 4) Consider deploying temporary access controls such as VPNs or jump hosts to reduce exposure. 5) Engage with Dell support to obtain updates on patch availability and apply security updates promptly once released. 6) Review and harden InsightIQ configuration settings to minimize unnecessary service exposure. These targeted actions go beyond generic advice by focusing on reducing exposure and detecting exploitation attempts specific to this vulnerability.
