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.
-
Identify ClearPass Policy Manager version via CLIAccess the ClearPass CLI and run the command to display the system version, typically `show version` or check the /var/www/html/VERSION file if accessibleAffected if The displayed version falls within any of these ranges: 6.6.0-6.6.10, 6.7.0-6.7.14, 6.8.0-6.8.8, or 6.9.0-6.9.5
-
Identify ClearPass Policy Manager version via web interfaceLog into the ClearPass web administration console and navigate to Administration > About or the version information pageAffected if The version shown is any of: 6.6.x prior to 6.6.11, 6.7.x prior to 6.7.15, 6.8.x prior to 6.8.9, or 6.9.x prior to 6.9.6
-
Check API or REST API endpoint versionIf the ClearPass API is accessible, query the version endpoint (typically /api/version or /api/system info) using an authenticated API requestAffected if The API returns a version number matching the affected ranges listed above
-
Confirm the guest operator or operator account feature is in useReview whether the Guest Operator or any operator account functionality is enabled in ClearPass, as command injection often targets operator interfacesAffected if Operator account features are enabled and the ClearPass version is within the vulnerable ranges
The environment is affected if ClearPass Policy Manager is running any version from 6.6.0 through 6.6.10, 6.7.0 through 6.7.14, 6.8.0 through 6.8.8, or 6.9.0 through 6.9.5.
