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 versionAccess the CLI or administrative web interface and locate the software version information, typically found in About or System Information sectionsAffected if The installed version falls within 6.8.0-6.8.8, 6.9.0-6.9.6, or 6.10.0-6.10.1 (the vulnerable ranges)
-
Verify web interface accessibilityDetermine whether the ClearPass Policy Manager management web interface (HTTPS port 443 or 8080) is reachable from network segments outside the trusted management networkAffected if The management web interface is exposed to untrusted or public networks, increasing exploitation likelihood
-
Review web access logs for SQL injection patternsExamine ClearPass web server access and error logs for unusual SQL syntax in URL parameters, especially in authentication or search-related endpointsAffected if Logs contain requests with SQL keywords (UNION, SELECT, INSERT, OR 1=1) in parameter values that did not originate from legitimate administrative actions
You are affected if your ClearPass Policy Manager version is below the fixed releases (6.8.9, 6.9.7, or 6.10.2) AND the management web interface is accessible from untrusted networks, or if logs show evidence of SQL injection attempts.
