Confidentiality: None
Integrity: None
Availability: High

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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).

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. Enforce strict access control policies limiting privileged access to ArubaOS devices only to trusted administrators. 2. Implement multi-factor authentication (MFA) for all administrative accounts to reduce the risk of credential compromise. 3. Monitor and audit all privileged user activities on ArubaOS devices to detect unusual or unauthorized actions promptly. 4. Segment network management interfaces to restrict access to ArubaOS devices from only secure and monitored networks. 5. Regularly back up device configurations and maintain an inventory of affected ArubaOS versions to prioritize patching. 6. Coordinate with Hewlett Packard Enterprise for timely receipt and deployment of firmware patches or updates addressing this vulnerability. 7. Develop and test incident response plans that include procedures for hardware replacement and network recovery in case of exploitation. 8. Educate administrators about the risks of this vulnerability and the importance of safeguarding privileged credentials. 9. Consider deploying network anomaly detection systems to identify potential exploitation attempts targeting ArubaOS devices. 10. Limit physical access to network hardware to prevent direct tampering that could facilitate exploitation.

Description

A vulnerability in an AOS firmware binary allows an authenticated malicious actor to permanently delete necessary boot information. Successful exploitation may render the system unbootable, resulting in a Denial of Service that can only be resolved by replacing the affected hardware.

Impact

For European organizations, the primary impact of CVE-2025-37139 is a severe disruption of network availability due to the permanent denial of service caused by unbootable ArubaOS devices. Enterprises, data centers, and critical infrastructure relying on ArubaOS for network access and management could experience extended outages, affecting business operations, communications, and service delivery. The need to replace hardware to recover increases downtime and operational costs. This risk is heightened in sectors with stringent uptime requirements such as finance, healthcare, telecommunications, and government. Additionally, the attack requires high privilege authentication, so compromised credentials or insider threats could enable exploitation. The vulnerability does not impact confidentiality or integrity directly but availability loss can indirectly affect data access and business continuity. Given the widespread use of ArubaOS in Europe, the threat could affect a broad range of organizations, from small businesses to large enterprises and public sector entities. The absence of known exploits currently provides a window for mitigation, but the permanent damage potential makes proactive defense critical.

Summary

CVE-2025-37139 is a vulnerability in the ArubaOS firmware binaries used in Hewlett Packard Enterprise's Aruba network devices. The flaw allows an authenticated attacker with high privileges to delete essential boot information from the device's firmware. This deletion is permanent and prevents the device from booting, effectively causing a denial of service. Recovery from this state is not possible through software means and requires physical replacement of the affected hardware, making the impact severe in terms of availability. The vulnerability affects multiple ArubaOS versions, including 8.10.0.0, 8.12.0.0, 8.13.0.0, 10.4.0.0, and 10.7.0.0. The CVSS v3.1 score is 6.0, indicating medium severity, with vector AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H, meaning the attack requires local access with low complexity, high privileges, no user interaction, and impacts availability with scope changed. No confidentiality or integrity impact is noted. No known exploits have been reported in the wild yet. The vulnerability is critical because it can cause permanent hardware damage, forcing device replacement and potentially causing extended network outages. ArubaOS devices are widely used in enterprise and service provider networks for wireless and wired connectivity, making this vulnerability a significant risk for network availability and business continuity. The requirement for authenticated high privilege access limits the attack surface but does not eliminate risk, especially if credential compromise or insider threats occur. The lack of patch links suggests that fixes may be pending or require vendor coordination. Organizations should monitor for updates and implement compensating controls to prevent unauthorized privileged access.

CWE-400Uncontrolled Resource Consumption (opens in a new tab)
Class weaknessLikelihood of exploit: High
The product does not properly control the allocation and maintenance of a limited resource.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place.
Architecture and Design
Mitigation of resource exhaustion attacks requires that the target system either: recognizes the attack and denies that user further access for a given amount of time, or; uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Architecture and Design
Ensure that protocols have specific limits of scale placed on them.
