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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Nov 2025
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 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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

Upgrade Dell PowerScale OneFS to versions later than 9.12.0.0 or to the next available patched release that addresses the cryptographic weakness.
If you cannot patch yet, restrict remote network access to OneFS management and data interfaces using network segmentation, firewalls, and VPNs to limit exposure.
Implement strict access control policies and monitor network traffic for unusual or unauthorized data access patterns indicative of exploitation attempts.
Employ additional encryption layers at the application or transport level (e.g., TLS 1.3) to mitigate risks from broken internal cryptography.
Conduct regular security audits and vulnerability assessments focusing on cryptographic configurations and compliance with best practices.
Maintain up-to-date incident response plans to quickly identify and contain any information disclosure incidents.
Engage with Dell support for guidance and early access to patches or workarounds.

Description

CVE-2025-43723 is a medium-severity vulnerability in Dell PowerScale OneFS affecting versions prior to 9.10.1.3 and 9.11.0.0 through 9.12.0.0.

Impact

For European organizations, the impact of CVE-2025-43723 is primarily the potential unauthorized disclosure of sensitive or confidential data managed by Dell PowerScale OneFS storage systems. This can affect sectors such as finance, healthcare, government, and critical infrastructure where data confidentiality is paramount. The vulnerability could lead to exposure of intellectual property, personal data protected under GDPR, or strategic business information, resulting in regulatory penalties, reputational damage, and competitive disadvantage. Since the exploit requires no authentication and can be performed remotely, attackers could leverage this vulnerability as an initial foothold or to gather intelligence without detection. The medium severity score indicates that while the attack complexity is high, the confidentiality impact is significant. European organizations relying heavily on Dell PowerScale for large-scale data storage and file sharing are at increased risk, especially if remote access controls are weak or if monitoring is insufficient.

The product uses a broken or risky cryptographic algorithm or protocol.
Architecture and Design · Libraries or Frameworks
When there is a need to store or transmit sensitive data, use strong, up-to-date cryptographic algorithms to encrypt that data. Select a well-vetted algorithm that is currently considered to be strong by experts in the field, and use well-tested implementations.
Architecture and Design
Ensure that the design allows one cryptographic algorithm to be replaced with another in the next generation or version. Where possible, use wrappers to make the interfaces uniform. This will make it easier to upgrade to stronger algorithms.
Architecture and Design
Carefully manage and protect cryptographic keys (see CWE-320). If the keys can be guessed or stolen, then the strength of the cryptography itself is irrelevant.
