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: 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 13 Jan 2026
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.

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 2026-10-26.

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. Monitor Hewlett Packard Enterprise communications closely for official patches or firmware updates addressing CVE-2025-37165 and apply them promptly once released. 2. Until patches are available, restrict access to the management interfaces and router mode configurations of HPE Instant On devices by implementing strict network segmentation and access control lists (ACLs) to limit exposure to trusted networks only. 3. Employ network traffic monitoring and anomaly detection to identify unusual packet inspection or reconnaissance activities targeting HPE Instant On devices. 4. Disable router mode on HPE Instant On Access Points if not required, or consider alternative deployment modes that do not expose internal network details. 5. Conduct regular network audits to identify and remediate any unintended exposure of sensitive network configuration data. 6. Educate network administrators on this vulnerability to ensure awareness and prompt response. 7. Consider deploying additional security layers such as VPNs or encrypted tunnels for management traffic to reduce the risk of packet inspection by unauthorized actors.

Description

A vulnerability in the router mode configuration of HPE Instant On Access Points exposed certain network configuration details to unintended interfaces. A malicious actor could gain knowledge of internal network configuration details through inspecting impacted packets.

Impact

The primary impact of CVE-2025-37165 is the unauthorized disclosure of sensitive internal network configuration details. This information leakage can significantly aid attackers in mapping the network, identifying critical assets, and planning subsequent attacks such as lateral movement, privilege escalation, or targeted exploitation of other vulnerabilities. While the vulnerability does not directly compromise device integrity or availability, the confidentiality breach can lead to increased risk of advanced persistent threats and data breaches. Organizations relying on HPE Instant On Access Points in router mode, especially in environments where network segmentation is weak or where these devices serve as primary gateways, face elevated risk. The exposure could be particularly damaging in sectors with sensitive data or critical infrastructure, including finance, healthcare, government, and manufacturing. The lack of required authentication or user interaction lowers the barrier for attackers, increasing the likelihood of exploitation once a public exploit or proof-of-concept becomes available.

Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
