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 BlackBerry Enterprise Server installationLocate the BlackBerry Enterprise Server installation directory or check installed programs on the server systemAffected if BlackBerry Enterprise Server is installed on the system
-
Determine the installed versionAccess the Management Console and navigate to the About or Server Information section to view the exact version number, or check the installation logs and registry for version detailsAffected if The installed version is 12.4 or any earlier version (12.0 through 12.4)
-
Verify Management Console accessibilityConfirm the Management Console web interface is accessible and functional by accessing its URL (typically https://server:8443 or similar)Affected if The Management Console is accessible and operational
-
Check for administrator accounts with basic accessReview the administrator accounts configured in the Management Console under User Management or Administrators section, noting their access level (basic vs. full)Affected if There exist administrator accounts assigned basic access permissions
-
Inspect the Export IT screen for suspicious contentNavigate to the Export IT policy screen within the Management Console and examine any existing policies for unusual HTML or script tags in policy fieldsAffected if Policies containing malicious HTML/script code are present and will execute when viewed on the Export IT screen
A user is affected if BlackBerry Enterprise Server version 12.4 or earlier is installed, the Management Console is accessible, and there is potential malicious content in policies that would render on the Export IT screen.
