Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.74% for the current model date.

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

  1. Confirm that the asset runs Hewlett Packard Enterprise (HPE) AOS-CX and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Summary
A vulnerability has been identified in the web-based management interface of AOS-CX switches that could potentially allow an unauthenticated remote actor to circumvent existing authentication controls. In some cases this could enable resetting the admin password.
Remediation
To address the vulnerabilities described above in the affected software branches, it is recommended to upgrade HPE Networking AOS-CX to one of the following versions (as applicable): - AOS-CX 10.17.xxxx: AOS-CX 10.17.1001 and above - AOS-CX 10.16.xxxx: AOS-CX 10.16.1030 and above - AOS-CX 10.13.xxxx: AOS-CX 10.13.1161 and above - AOS-CX 10.10.xxxx: AOS-CX 10.10.1180 and above Software versions with resolution/fixes for the vulnerabilities covered above can be downloaded from the HPE Networking Support Portal at https://networkingsupport.hpe.com/home/ HPE Aruba Networking does not evaluate or patch software branches that have reached their End of Maintenance (EoM) milestone.

01

What, why and how

A vulnerability has been identified in the web-based management interface of AOS-CX switches that could potentially allow an unauthenticated remote actor to circumvent existing authentication controls. In some cases this could enable resetting the admin password.

What

A vulnerability has been identified in the web-based management interface of AOS-CX switches that could potentially allow an unauthenticated remote actor to circumvent existing authentication controls. In some cases this could enable resetting the admin password.

Why

The affected component does not establish the requesting party's identity reliably before granting access.

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.

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

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
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

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 → Improper Authentication → cause the confidentiality, integrity or availability impact described by the vendor

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-287 ↗

CWE-287: Improper Authentication. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
