Compensating controls
- Validate the affected product branch and deploy the verified fixed release.
- Restrict the affected network interface to trusted sources where business-safe.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs Hewlett Packard Enterprise (HPE) Instant On and falls inside the recorded affected range.
- Verify the installed build against the product-specific fixed version after deployment.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

- Instant On
- Summary
- 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.
- Remediation
- Upgrade to HPE Networking Instant On software version 3.3.2.0 and above. Please note that Instant On devices started updating automatically during the week of December 10, 2025. No action is required from customers for this to occur, but manual upgrades may be triggered via the Instant On app or web portal after the release date. Note: These vulnerabilities only affect HPE Networking Instant On Access Points only. HPE Networking Instant On Switches are not affected. HPE Aruba Networking does not evaluate or patch software branches that have reached their End of Support Life (EoSL) milestone.

What, why and how
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.
What
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.
Why
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
- Likely attack path
- a network path → Exposure of Sensitive Information to an Unauthorized Actor → cause the confidentiality, integrity or availability impact described by the vendor
- Attack surface
- Network
- Privileges required
- None: unauthenticated exploitation is possible
- User interaction
- None
- Attack complexity
- Low: no specialised conditions are recorded
- Security boundary
- Unchanged: impact remains within the vulnerable component's security authority
- Weakness
?
CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-200 ↗
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
