Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability in the ClearPass OnGuard Linux agent could allow malicious users on a Linux instance to elevate their user privileges. A successful exploit could allow these users to execute arbitrary code with root level privileges on the Linux instance in Aruba ClearPass Policy Manager version(s): ClearPass Policy Manager 6.10.x: 6.10.7 and below and ClearPass Policy Manager 6.9.x: 6.9.12 and below.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The ClearPass OnGuard Linux agent has a local privilege escalation vulnerability that allows authenticated malicious users to execute arbitrary code with root privileges. This is a local privilege escalation flaw in the endpoint protection agent running on Linux systems managed by ClearPass Policy Manager.

MitigationUpgrade ClearPass Policy Manager to version 6.10.8 or higher (for 6.10.x branches) or 6.9.13 or higher (for 6.9.x branches) to address the vulnerability in the OnGuard Linux agent component.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify ClearPass Policy Manager installation and version
    Locate the ClearPass Policy Manager installation and determine its installed version number (for example, via system inventory, package manager, or administrative interface)
    Affected if The installed version is 6.9.0 through 6.9.11 inclusive, or 6.10.0 through 6.10.6 inclusive (vulnerable ranges)
  2. Check for OnGuard Linux agent deployment
    Determine whether the OnGuard Linux agent component is deployed on managed Linux endpoints in the environment (for example, via endpoint inventory, agent status check, or ClearPass administrative console)
    Affected if OnGuard Linux agent is installed and running on Linux systems managed by the ClearPass Policy Manager
  3. Verify authenticated user access
    Identify whether standard or non-privileged user accounts have authenticated access to systems where the OnGuard Linux agent is deployed
    Affected if Non-root users have authenticated access to Linux endpoints with the OnGuard agent (the vulnerability allows such users to escalate to root)

You are affected if you have ClearPass Policy Manager version 6.9.0-6.9.11 or 6.10.0-6.10.6 with the OnGuard Linux agent deployed and non-administrative users have authenticated access to those endpoints.

Upgrade available Upgrade to 6.9.12 / 6.10.7 or later
Fixed in 6.9.126.10.7
Interim mitigation

Upgrade ClearPass Policy Manager to version 6.10.8 or higher (for 6.10.x branches) or 6.9.13 or higher (for 6.9.x branches) to address the vulnerability in the OnGuard Linux agent component.

Recommended fix High confidence

ClearPass Policy Manager 6.9.12 (for 6.9.x branches) or 6.10.7 (for 6.10.x branches)

  1. 1. Identify the current installed version of ClearPass Policy Manager by navigating to Administration > About > Copyright in the ClearPass web UI
  2. 2. If running version 6.9.x (6.9.0 through 6.9.11), plan upgrade to version 6.9.12 or later
  3. 3. If running version 6.10.x (6.10.0 through 6.10.6), plan upgrade to version 6.10.7 or later
  4. 4. Review Aruba upgrade documentation and release notes for the target version
  5. 5. Take a full backup of the ClearPass configuration before upgrading
  6. 6. Schedule a maintenance window as the upgrade will require service downtime
  7. 7. Download the appropriate upgrade package from the Aruba support portal (https://asp.arubanetworks.com)
  8. 8. Apply the upgrade following Aruba's standard upgrade procedure for ClearPass Policy Manager
Caveat Standard upgrade risks apply - ensure configuration backup before proceeding; review release notes for any behavioral changes between versions
