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 0.54% 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: 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.

  • HPE Networking ClearPass Policy Manager (CPPM)
Summary
Deserialization of untrusted data vulnerabilities exist in the web interface of HPE Networking ClearPass Policy Manager. Successful exploitation could allow an unauthenticated remote attacker to execute arbitrary code on the affected system.
Remediation
To address the vulnerabilities described in the Details Section, HPE Networking recommends upgrading the HPE Networking ClearPass Policy Manager (CPPM) products to the following software versions (as applicable): - CPPM 6.14.1 and above - CPPM 6.11.16 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 NOTE: 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. For deployments running software versions that are past End of Support (EoS), HPE Networking has not assessed exposure to the vulnerabilities referenced in this advisory. As a result, such installations should be considered potentially impacted by the listed CVE. Customers are strongly encouraged to upgrade to a supported software release to ensure proper evaluation and remediation.

01

What, why and how

Deserialization of untrusted data vulnerabilities exist in the web interface of HPE Networking ClearPass Policy Manager. Successful exploitation could allow an unauthenticated remote attacker to execute arbitrary code on the affected system.

What

Deserialization of untrusted data vulnerabilities exist in the web interface of HPE Networking ClearPass Policy Manager. Successful exploitation could allow an unauthenticated remote attacker to execute arbitrary code on the affected system.

Why

Attacker-influenced serialised data is reconstructed as trusted objects, which can invoke dangerous application behaviour.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may execute code or commands in the affected security context.

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 → Deserialization of Untrusted Data → execute code or commands in the affected security context

None: unauthenticated exploitation is possible

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-502 ↗

CWE-502: Deserialization of Untrusted Data. The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

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

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UINoneUser interaction: No action by another user is required.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.AHighAvailability impact: A successful attack can cause a major loss.
Post-exploitation / living off the land
After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.
