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.

- HPE Networking ClearPass Policy Manager (CPPM)
- Summary
- A command injection vulnerability in the OnGuard agent of ClearPass Policy Manager could allow an authenticated remote attacker to inject arbitrary commands. Successful exploitation could allow an attacker to execute commands with elevated privileges on the affected Windows endpoint.
- 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.
Medium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority.

What, why and how
A command injection vulnerability in the OnGuard agent of ClearPass Policy Manager could allow an authenticated remote attacker to inject arbitrary commands. Successful exploitation could allow an attacker to execute commands with elevated privileges on the affected Windows endpoint.
What
A command injection vulnerability in the OnGuard agent of ClearPass Policy Manager could allow an authenticated remote attacker to inject arbitrary commands. Successful exploitation could allow an attacker to execute commands with elevated privileges on the affected Windows endpoint.
Why
Untrusted input reaches a command interpreter without sufficient validation or separation from command syntax.
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.

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 Neutralization of Special Elements used in a Command ('Command Injection') → execute code or commands in the affected security context
- 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-77 ↗
CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'). The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
- 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:N/I:L/A:LCommon 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.CNoneConfidentiality impact: No direct loss is represented by this metric.ILowIntegrity impact: A successful attack can cause a limited loss.ALowAvailability impact: A successful attack can cause a limited 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.
