Integrity: None
Availability: High

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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 18 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 2026-10-25.

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.

AI-suggested

1. Apply official patches from Hewlett Packard Enterprise as soon as they become available to address the vulnerability. 2. Restrict administrative access to ArubaOS-CX devices using network segmentation, multi-factor authentication, and strict access control lists to minimize the risk of privilege misuse. 3. Implement robust monitoring and logging of administrative activities to detect anomalous behavior indicative of exploitation attempts. 4. Regularly audit user accounts and permissions to ensure only authorized personnel have administrative privileges. 5. Maintain offline backups of device configurations and have a recovery plan to restore network functionality quickly in case of device failure. 6. Consider deploying redundant network paths and failover mechanisms to mitigate the impact of a single device becoming non-functional. 7. Educate network administrators on the risks and signs of exploitation to enhance early detection and response.

Description

A platform-level denial-of-service (DoS) vulnerability exists in ArubaOS-CX software. Successful exploitation of this vulnerability could allow an attacker with administrative access to execute specific code that renders the switch non-bootable and effectively non-functional.

Impact

For European organizations, exploitation of CVE-2025-37156 could lead to significant network outages due to the non-bootable state of critical ArubaOS-CX switches. This can disrupt business operations, data center connectivity, and enterprise communications, especially in sectors relying heavily on network availability such as finance, healthcare, telecommunications, and government. The denial-of-service condition could also impact service level agreements and regulatory compliance related to network uptime. Since administrative access is required, the threat is more pronounced from insider threats or attackers who have already compromised privileged credentials. The loss of a switch could necessitate physical intervention or device replacement, increasing operational costs and downtime. Given the widespread use of HPE Aruba networking equipment in Europe, the potential impact is broad, affecting both private and public sector organizations.
