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.

The vendor explicitly identifies these products as affected by this CVE.
- HPE Networking ClearPass Policy Manager (CPPM)
- Summary
- An authenticated path traversal vulnerability exists in ClearPass Policy Manager. Successful exploitation could allow an attacker to read and modify certain files on the underlying operating 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.

What, why and how
An authenticated path traversal vulnerability exists in ClearPass Policy Manager. Successful exploitation could allow an attacker to read and modify certain files on the underlying operating system.
What
An authenticated path traversal vulnerability exists in ClearPass Policy Manager. Successful exploitation could allow an attacker to read and modify certain files on the underlying operating system.
Why
Attacker-controlled path data is not constrained to the intended directory before the application accesses a file.
How
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

02
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 → Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') → cause the confidentiality, integrity or availability impact described by the vendor
- Attack surface
- Network
- Privileges required
- None: unauthenticated exploitation is possible
- User interaction
- None
- Attack complexity
- Low: no specialised conditions are recorded
- Security boundary
- Unchanged: impact remains within the vulnerable component's security authority
- Weakness
?
CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-22 ↗
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'). The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
- 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:HCommon 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
- 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.
