Integrity: Low
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 22 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade PowerScale OneFS and dell/powerscale-onefs to 9.13.0.0.

AI-suggested

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.

Description

Dell PowerScale OneFS, versions prior 9.13.0.0, contains an insufficient logging vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to information tampering.

Impact

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.

Base weaknessLikelihood of exploit: MediumOWASP Top 10 A09:2025: Security Logging & Alerting Failures (opens in a new tab)
When a security-critical event occurs, the product either does not record the event or omits important details about the event when logging it.
Architecture and Design
Use a centralized logging mechanism that supports multiple levels of detail.
Implementation
Ensure that all security-related successes and failures can be logged. When storing data in the cloud (e.g., AWS S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to enable and capture detailed logging information.
Operation
Be sure to set the level of logging appropriately in a production environment. Sufficient data should be logged to enable system administrators to detect attacks, diagnose errors, and recover from attacks.
