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 installed BlackBerry UEM versionAccess the UEM administration console or check system information to determine the exact version number of the installed BlackBerry Unified Endpoint ManagerAffected if The installed version is 12.8.0 or 12.8.1 specifically
-
Confirm Management Console is accessibleVerify that the UEM Management Console interface is accessible and exposed to users or administratorsAffected if The Management Console is reachable and the system is running an affected version (12.8.0 or 12.8.1)
-
Review session management configurationInspect session management settings within the UEM console to determine if session tokens or credentials are being handled securelyAffected if Session tokens are exposed or session management does not properly protect credentials from disclosure
-
Audit for suspicious session activityReview session logs and authentication records for unauthorized access attempts or session hijacking indicatorsAffected if Unauthorized sessions or impersonation attempts are observed in logs
A user is affected if BlackBerry UEM version 12.8.0 or 12.8.1 is installed and the Management Console is accessible, as the vulnerability enables session credential disclosure leading to potential session hijacking.
