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 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.

AI-suggested

Implement strict network segmentation to isolate ArubaOS management interfaces from untrusted networks, limiting exposure to potential attackers.
Employ access control lists (ACLs) and firewall rules to restrict inbound traffic to ArubaOS devices only from trusted sources.
Monitor ArubaOS device logs and network traffic for signs of abnormal process crashes or repeated service interruptions that could indicate exploitation attempts.
Prepare incident response plans to quickly address potential denial-of-service events impacting wireless infrastructure.
Engage with HPE support channels to obtain updates on patches or workarounds as they become available and prioritize timely deployment.
Consider deploying redundant wireless controllers or failover mechanisms to maintain network availability in case of service disruption.
Regularly audit and update ArubaOS firmware and configurations to minimize exposure to known vulnerabilities.
Limit exposure of ArubaOS devices to the internet or untrusted networks wherever possible to reduce attack surface.

Description

CVE-2025-37178 is a medium severity vulnerability in Hewlett Packard Enterprise's ArubaOS versions 8.10.0.0 and 8.12.0.0. It involves multiple out-of-bounds read flaws due to improper validation of buffer size values, which can cause the affected process to read beyond allocated memory. Exploitation under specific conditions may lead to process crashes and denial-of-service (DoS) conditions. The vulnerability does not impact confidentiality or integrity and requires no authentication or user interaction.

Impact

For European organizations, the primary impact of CVE-2025-37178 is the potential disruption of network services due to process crashes causing denial-of-service conditions. ArubaOS is commonly deployed in enterprise wireless networks, including in sectors such as finance, healthcare, government, and critical infrastructure. A successful exploit could interrupt wireless connectivity, impacting business operations, communications, and access to critical applications. Although the vulnerability does not compromise data confidentiality or integrity, availability interruptions can lead to operational downtime, reduced productivity, and potential cascading effects on dependent systems. Organizations with high reliance on ArubaOS-managed wireless environments, especially those with limited redundancy or failover capabilities, are at increased risk. The lack of authentication requirements for exploitation means attackers could target exposed network interfaces remotely, emphasizing the need for network segmentation and access controls. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, especially as threat actors may develop exploits over time.
