Published severityMediumOperational priority:Low, lowered one band.downgradedsince 26 Feb 2026

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.26% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Hewlett Packard Enterprise (HPE) HPE Aruba Networking 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: No default targetRemediation target: Normal maintenance

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.

  • AOS-CX
Summary
A vulnerability in the web management interface of the AOS-CX OS user authentication service could allow an authenticated remote attacker to hijack an active user session. Successful exploitation may enable the attacker to maintain unauthorized access to the session, potentially leading to the view or modification of sensitive configuration data.
Remediation
To address the vulnerabilities described above in the affected software branches, it is recommended to upgrade HPE Aruba Networking AOS-CX to one of the following versions (as applicable): - AOS-CX 10.16.xxxx: AOS-CX 10.16.1006 and above - AOS-CX 10.15.xxxx: AOS-CX 10.15.1030 and above - AOS-CX 10.14.xxxx: AOS-CX 10.14.1060 and above - AOS-CX 10.13.xxxx: AOS-CX 10.13.1101 and above - AOS-CX 10.10.xxxx: AOS-CX 10.10.1170 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.

What, why and how

A vulnerability in the web management interface of the AOS-CX OS user authentication service could allow an authenticated remote attacker to hijack an active user session. Successful exploitation may enable the attacker to maintain unauthorized access to the session, potentially leading to the view or modification of sensitive configuration data.

What

A vulnerability in the web management interface of the AOS-CX OS user authentication service could allow an authenticated remote attacker to hijack an active user session. Successful exploitation may enable the attacker to maintain unauthorized access to the session, potentially leading to the view or modification of sensitive configuration data.

Why

Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.

How

An attacker operating through local access may attempt exploitation with elevated privileges. 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
?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
local access → Session Fixation → 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-384 ↗

CWE-384: Session Fixation. Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.

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

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRHighPrivileges required: The attacker needs elevated or administrative privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.ANoneAvailability impact: No direct loss is represented by this metric.

The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.
