Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.36% 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) ClearPass Policy Manager (CPPM) 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: As exposure requiresRemediation target: Within 365 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 in the ClearPass OnGuard agent could allow an authenticated remote attacker to elevate their own privileges on a vulnerable ClearPass OnGuard deployment. Successful exploitation could allow an attacker to obtain root privileges, leading to potentially unauthorized operation of the vulnerable system.
Remediation
To address the vulnerabilities described above in the affected software branches, it is recommended to upgrade HPE Networking ClearPass Policy Manager to one of the following versions: HPE Networking ClearPass Policy Manager - 6.14.x: ClearPass 6.14.0 and above - 6.12.x: ClearPass 6.12.8-HF and above - 6.11.x: ClearPass 6.11.15 and above NOTE: Customers running HPE Networking ClearPass Policy Manager 6.12.x are encouraged to upgrade to a supported software branch for complete remediation. 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.

01

What, why and how

A vulnerability in the ClearPass OnGuard agent could allow an authenticated remote attacker to elevate their own privileges on a vulnerable ClearPass OnGuard deployment. Successful exploitation could allow an attacker to obtain root privileges, leading to potentially unauthorized operation of the vulnerable system.

What

A vulnerability in the ClearPass OnGuard agent could allow an authenticated remote attacker to elevate their own privileges on a vulnerable ClearPass OnGuard deployment. Successful exploitation could allow an attacker to obtain root privileges, leading to potentially unauthorized operation of the vulnerable 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 a network path may attempt exploitation with low 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.

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.
