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 Oracle Flexcube Universal Banking versionCheck the application's about page, version info in the admin console, or consult Oracle installation documentation for version lookup methods. Typical locations include: product header files, version.properties, or the admin UI.Affected if The installed version falls within 12.1.0-12.4.0, 14.0.0-14.3.0, or 14.5.0
-
Confirm Infrastructure component is deployedReview the Oracle Flexcube deployment configuration to verify the Infrastructure module is installed and active. Check application server configuration files or admin console for enabled modules.Affected if The Infrastructure component is present and enabled in the deployment
-
Verify network accessibility via HTTPDetermine if the Flexcube application is accessible over HTTP/HTTPS from network locations. Check load balancer, web server, or firewall rules that expose the application port.Affected if The application is reachable via HTTP from network locations accessible to low-privileged users
-
Check for existence of low-privileged application accountsReview user directories, database user tables, or application user management to identify whether low-privileged accounts exist that could be used for initial access.Affected if Low-privileged user accounts are present in the system that could be compromised for initial access
The environment is affected if Oracle Flexcube Universal Banking version is 12.1.0-12.4.0, 14.0.0-14.3.0, or 14.5.0, the Infrastructure component is deployed, and the application is network-accessible via HTTP with low-privileged accounts present.
