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 checksWork through these to decide whether this CVE applies to you.
-
Confirm ClearPass Policy Manager is installedIdentify whether HPE Aruba ClearPass Policy Manager software is present on the system or accessing the management interface.Affected if ClearPass Policy Manager is found on the system
-
Determine the installed versionLocate and retrieve the installed version of ClearPass Policy Manager. This is typically accessible via the admin web interface, command line, or system information files.Affected if The version cannot be determined or the software is not present
-
Compare version against affected rangeCheck if the installed version falls within >= 6.6.0 and < 6.6.5Affected if Installed version is 6.6.0, 6.6.1, 6.6.2, 6.6.3, or 6.6.4 (any version from 6.6.0 up to but not including 6.6.5)
-
Assess management interface accessibilityDetermine if the ClearPass Policy Manager admin interface (typically port 443 or 8443) is reachable from network segments outside the trusted management network.Affected if The management interface is exposed to untrusted networks and the installed version is within the affected range
The environment is affected if ClearPass Policy Manager version 6.6.0 through 6.6.4 is installed and its management interface is accessible, since an authenticated attacker could exploit the RCE vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data6.6.5
Apply the vendor patch or upgrade to a patched version of ClearPass Policy Manager. Restrict network access to the management interface to trusted personnel only until the patch is applied.
