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 if BlackBerry Enterprise Server is installedCheck for BlackBerry Enterprise Server installation directories, services, or registry entries on the system. Look for BES12 or BlackBerry Enterprise Server components in Program Files or system directories.Affected if BlackBerry Enterprise Server is found on the system
-
Determine the installed version of BlackBerry Enterprise ServerUse system inventory tools, check installed software listings, or query the BlackBerry Enterprise Server service information to retrieve the exact version number.Affected if The installed version is 12.4 or any version lower than 12.4.1
-
Verify the Management Console web interface is accessibleCheck if the BES12 Management Console web service is running and reachable. This is typically accessed via a browser to the configured Management Console URL.Affected if The Management Console is exposed and the installed version is 12.4 or below
-
Confirm the vulnerability scopeThe XSS flaw exists in how the Management Console handles user-supplied input in URLs before rendering it in the response. If the Management Console is accessible and the version is within the affected range, the environment is potentially vulnerable.Affected if The Management Console is active and the version is 12.4 or lower
A user is affected if BlackBerry Enterprise Server version 12.4 or lower is installed and the Management Console web interface is accessible.
