Published severityMediumOperational priority:Low, lowered one band.downgradedsince 1 Sep 2026

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.14% 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) Fabric Composer 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.

Summary
A local privilege escalation vulnerability in HPE Networking Fabric Composer could allow an authenticated privileged user on the underlying host to elevate their user privileges to those of a higher role. A successful exploit allows the attacker to change the state of certain settings of the affected system.
Remediation
To resolve all the vulnerabilities in the affected software branches that are addressed through this advisory, HPE Networking strongly recommends upgrading the HPE Networking Fabric Composer software to one of the following versions (as applicable): - HPE Networking Fabric Composer 7.4.x: 7.4.0 and above - HPE Networking Fabric Composer 7.3.x: 7.3.4 and above Software versions with resolution/fixes for the vulnerabilities in this advisory can be downloaded from the HPE Networking Support Portal at https://networkingsupport.hpe.com/home/. Product software versions that have reached End of Maintenance (EoM) are presumed to be affected by the vulnerabilities unless explicitly stated otherwise, and are not covered by this security advisory. HPE Networking does not evaluate or patch software branches that have reached their End of Support (EoS) milestone.

What, why and how

A local privilege escalation vulnerability in HPE Networking Fabric Composer could allow an authenticated privileged user on the underlying host to elevate their user privileges to those of a higher role. A successful exploit allows the attacker to change the state of certain settings of the affected system.

What

A local privilege escalation vulnerability in HPE Networking Fabric Composer could allow an authenticated privileged user on the underlying host to elevate their user privileges to those of a higher role. A successful exploit allows the attacker to change the state of certain settings of the affected system.

Why

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

How

An attacker operating through local access may attempt exploitation with elevated privileges. If successful, the issue may gain additional privileges.

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 → Improper Privilege Management → gain additional privileges
Attack surface

CWE-269 ↗

CWE-269: Improper Privilege Management. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

?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.
