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: None: The vulnerable system can be exploited without any interaction from any user.
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: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

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 30 Oct 2026.

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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity 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

AI-suggested

If you cannot patch yet, organizations should implement specific mitigations to reduce risk. These include restricting remote access to the OneFS management interfaces and authentication services using network segmentation, firewalls, or VPNs to limit exposure to trusted networks only. Monitoring account lockout events and implementing alerting can help detect potential exploitation attempts early. Administrators should review and adjust account lockout policies to balance security and availability, possibly increasing thresholds or lockout durations temporarily. Employing multi-factor authentication (MFA) where supported can reduce the impact of account lockouts on critical users. Additionally, maintaining up-to-date backups and having incident response plans for DoS scenarios will aid in recovery. Organizations should track Dell security advisories closely for patches or updates addressing this vulnerability and apply them promptly once available.

Description

Dell PowerScale OneFS, version 9.13.0.0, contains an overly restrictive account lockout mechanism vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to denial of service.

Impact

The primary impact of CVE-2026-25907 is denial of service, where attackers can remotely lock out user accounts, preventing legitimate access to Dell PowerScale OneFS systems. This can disrupt enterprise storage operations, affecting data availability and potentially halting business-critical processes dependent on the storage cluster. Since the vulnerability does not compromise confidentiality or integrity, data theft or manipulation is not a direct concern. However, the availability impact can lead to operational downtime, increased support costs, and potential cascading effects on dependent applications and services. Organizations with large-scale deployments or those using OneFS in high-availability environments may experience significant operational disruption. The ease of exploitation (no authentication or user interaction required) increases the risk of automated or widespread attacks, especially in environments exposed to untrusted networks.

CWE-645Overly Restrictive Account Lockout Mechanism (opens in a new tab)
Base weaknessLikelihood of exploit: High
The product contains an account lockout protection mechanism, but the mechanism is too restrictive and can be triggered too easily, which allows attackers to deny service to legitimate users by causing their accounts to be locked out.
Architecture and Design
Implement more intelligent password throttling mechanisms such as those that take IP address into account, in addition to the login name.
Architecture and Design
Implement a lockout timeout that grows as the number of incorrect login attempts goes up, eventually resulting in a complete lockout.
Architecture and Design
Consider alternatives to account lockout that would still be effective against password brute force attacks, such as presenting the user machine with a puzzle to solve (making it do some computation).
