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

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. Check ClearPass Policy Manager version via CLI
    Access the ClearPass CLI through SSH and run the command to display the system version (typically 'show version' or similar system info command)
    Affected if The displayed version falls within any of these ranges: < 6.8.9, 6.8.9, 6.9.0 through 6.9.9, or 6.10.0 through 6.10.4
  2. Check ClearPass Policy Manager version via web interface
    Log into the ClearPass web administration console and navigate to the About or System Information page to view the installed version
    Affected if The version shown is lower than 6.8.9, equals 6.8.9, is between 6.9.0 and 6.9.9, or is between 6.10.0 and 6.10.4
  3. Check ClearPass version via API
    Use the ClearPass API endpoint (if accessible) to query the system version information programmatically
    Affected if The API returns a version matching any of the affected ranges: < 6.8.9, 6.8.9, 6.9.x (where x is 0-9), or 6.10.x (where x is 0-4)
  4. Identify if ClearPass is directly internet-facing
    Review network configuration and firewall rules to determine if the ClearPass Policy Manager management interface or web portal is exposed to the internet
    Affected if ClearPass management interfaces are reachable from untrusted networks and the version is within the affected ranges

Your environment is affected if the installed ClearPass Policy Manager version matches any of these: versions below 6.8.9, exactly version 6.8.9, versions 6.9.0 through 6.9.9, or versions 6.10.0 through 6.10.4.

Upgrade available Upgrade to 6.8.9 / 6.9.10 / 6.10.5 or later
Fixed in 6.8.96.9.106.10.5
Interim mitigation

Recommended fix High confidence

Upgrade to 6.10.5 (for 6.10.x branch), 6.9.10 (for 6.9.x branch), or 6.8.9-HF2 (for 6.8.x branch). For 6.7.x, upgrade to a supported branch (6.8.9 or later)

  1. Identify the currently installed ClearPass Policy Manager version via the WebUI or CLI
  2. Navigate to the ClearPass Policy Manager administration interface
  3. Back up the current configuration before upgrading
  4. Download the appropriate upgrade image from Aruba's support portal for your version branch
  5. Upload the upgrade image via the ClearPass Policy Manager WebUI (Administration > Server Manager > Server Configuration > Server Details > Upgrade)
  6. Follow the on-screen prompts to complete the upgrade process
  7. After upgrade, verify the ClearPass services are running and the WebUI is accessible
  8. Confirm the version has been updated to the fixed release
Caveat Review Aruba's upgrade guide for any migration considerations; ensure compatibility with connected infrastructure before upgrading
