CVE-2026-22279 identifies an insufficient logging vulnerability in Dell PowerScale OneFS, a clustered storage operating system widely used in enterprise environments for scalable file storage solutions. The flaw exists in versions prior to 9.13.0.0, where the system fails to adequately log certain security-relevant events. This insufficiency can be exploited remotely by an unauthenticated attacker who has network access to the system. Although the attacker cannot directly gain elevated privileges or cause denial of service, the lack of proper logging can enable information tampering to go undetected, undermining the integrity of stored data or audit trails. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) indicates that the attack vector is network-based, requires low attack complexity, no privileges, but does require user interaction, and impacts integrity only. The vulnerability is categorized under CWE-778 (Insufficient Logging), highlighting the risk of inadequate audit trails that can hinder incident detection and response. No patches or exploits are currently documented, but the risk remains for organizations that do not upgrade or implement compensating controls.

For European organizations, the primary impact of this vulnerability lies in the potential for undetected tampering with information stored or processed by Dell PowerScale OneFS systems. This can affect data integrity and forensic investigations, especially in sectors where audit trails are critical, such as finance, healthcare, and government. The inability to reliably detect or trace malicious activity could lead to prolonged breaches or data manipulation without timely detection. While confidentiality and availability are not directly impacted, the integrity compromise can undermine trust in data and compliance with regulatory requirements like GDPR, which mandates accountability and traceability of data processing activities. Organizations relying heavily on PowerScale for critical storage may face operational risks if attackers exploit this vulnerability to cover tracks or alter logs.

Organizations should prioritize upgrading Dell PowerScale OneFS to version 9.13.0.0 or later once patches become available from Dell. Until then, they should enhance monitoring by implementing external logging and audit solutions that capture and preserve security-relevant events independently of the vulnerable system’s native logs. Network segmentation and strict access controls should be enforced to limit remote access to PowerScale systems, reducing exposure to unauthenticated attackers. Additionally, organizations should conduct regular integrity checks on stored data and audit logs to detect anomalies. Incident response plans should be updated to consider the possibility of tampered logs, including using alternative data sources for forensic analysis. Finally, user training to recognize and report suspicious activities related to storage systems can help mitigate the requirement for user interaction exploitation.
