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.
-
Verify ClearPass Policy Manager is installedAccess the ClearPass Policy Manager web UI by navigating to the management interface URL, or log into the CLI and run 'show version' to confirm the product is present.Affected if ClearPass Policy Manager is not installed, this CVE does not apply.
-
Determine the installed version via web UILog into the ClearPass Policy Manager web interface and navigate to Administration > About, or access the /about endpoint, to view the exact version number.Affected if Unable to retrieve version information indicates ClearPass may not be accessible or installed.
-
Compare version against affected rangesCheck if the installed version falls within: 6.7.0 through 6.7.13, 6.7.14 (base), 6.8.0 through 6.8.8, or 6.9.0 through 6.9.4. These versions are all affected.Affected if Installed version is 6.7.0-6.7.13, 6.7.14, 6.8.0-6.8.8, or 6.9.0-6.9.4.
-
Confirm the web interface is accessibleVerify the ClearPass Policy Manager web UI is reachable on the network. The XSS vulnerability exists in the web interface component.Affected if Web interface is not accessible, the XSS flaw cannot be exploited though the vulnerable code may still be present.
If ClearPass Policy Manager version is 6.7.0-6.7.13, 6.7.14, 6.8.0-6.8.8, or 6.9.0-6.9.4 and the web UI is accessible, the environment is affected by this XSS vulnerability.
