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.
-
Confirm BlackBerry UEM is installedLocate BlackBerry UEM installation directories or check system services for UEM componentsAffected if BlackBerry UEM is not present on the system
-
Determine installed UEM versionAccess UEM admin console, check installation logs, or run version command specific to BlackBerry UEM to obtain the exact version numberAffected if Version is 12.12.0 or earlier, 12.12.1a, 12.13.0, or 12.13.1
-
Verify Management Console is enabledCheck if the Management Console web interface is accessible by attempting to reach the console URL or reviewing UEM service configurationAffected if Management Console is active and exposed
-
Assess Management Console access controlsReview user roles, permissions, and network access settings for the Management Console to determine if untrusted users can access itAffected if Management Console is accessible to untrusted or unauthorized users
System is affected if BlackBerry UEM version is 12.12.0 or earlier, 12.12.1a, 12.13.0, or 12.13.1 AND the Management Console is accessible to untrusted users

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade BlackBerry UEM to a version beyond 12.13.1 QF2 and 12.12.1a QF6 that includes the security patch. Restrict access to the Management Console to trusted users only as a compensating control.
