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
- Confirm that the asset runs Hewlett Packard Enterprise (HPE) ClearPass Policy Manager (CPPM) and falls inside the recorded affected range.
- Verify the installed build against the product-specific fixed version after deployment.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

- Aruba ClearPass Policy Manager
- Summary
- A vulnerability exists in ClearPass Policy Manager that allows for an attacker with administrative privileges to access sensitive information in a cleartext format. A successful exploit allows an attacker to retrieve information which could be used to potentially gain further access to network services supported by ClearPass Policy Manager.
- Remediation
- Upgrade ClearPass Policy Manager to one of the following versions with the fixes to resolve all issues noted in the details section. - ClearPass Policy Manager 6.12.x: 6.12.2 and above - ClearPass Policy Manager 6.11.x: 6.11.9 and above - In addition, for CVE-2024-3596 the following steps need to be taken to enable the RADIUS Message-Authenticator on ClearPass Navigate to Administration > Server Manager > Server Configuration screen, select each server individually to enable Message-Authenticator support. On the server screen, navigate to Service Parameters tab, select the Radius server service Under the Security header, modify the parameters Require Message-Authenticator from NAD = yes Require Message-Authenticator from Proxy Server = yes Save the changes. This will then restart the service with the requirement that the Message-Authenticator be transmitted, or the request will not be processed. HPE Aruba Networking does not evaluate or patch ClearPass Policy Manager versions that have reached their End of Support (EoS) milestone. Supported versions as of the publication date of this advisory are: - ClearPass Policy Manager 6.12.x - ClearPass Policy Manager 6.11.x Software versions with resolution/fixes for the vulnerabilities covered above, can be downloaded from the HPE Networking Support Portal. https://networkingsupport.hpe.com/home; For more information about HPE Aruba Networking's End of Support policy visit: https://www.arubanetworks.com/support-services/end-of-life/

What, why and how
A vulnerability exists in ClearPass Policy Manager that allows for an attacker with administrative privileges to access sensitive information in a cleartext format. A successful exploit allows an attacker to retrieve information which could be used to potentially gain further access to network services supported by ClearPass Policy Manager.
What
A vulnerability exists in ClearPass Policy Manager that allows for an attacker with administrative privileges to access sensitive information in a cleartext format. A successful exploit allows an attacker to retrieve information which could be used to potentially gain further access to network services supported by ClearPass Policy Manager.
Why
The current structured CVE record identifies a security weakness, but the root cause requires confirmation in the linked vendor material.
How
An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may obtain information outside the intended access boundary.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.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 None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.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 → vulnerable operation → obtain information outside the intended access boundary

- Privileges required
- High: elevated access is required

- Weakness
?
CWE means Common Weakness Enumeration. - CWE not yet assigned
- 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:H/UI:N/S:C/C:H/I:N/A:NCommon 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.PRHighPrivileges required: The attacker needs elevated or administrative privileges.UINoneUser interaction: No action by another user is required.SChangedScope: The attack can affect a component governed by a different security authority.CHighConfidentiality impact: A successful attack can cause a major loss.INoneIntegrity impact: No direct loss is represented by this metric.ANoneAvailability impact: No direct loss is represented by this metric.- Post-exploitation / living off the land
- No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
