dbcve analysis · moderate confidence

Vulnerability in Oracle FLEXCUBE Universal Banking Infrastructure component allows low privileged attackers with network access via HTTP to compromise the system. Successful exploitation requires human interaction and enables unauthorized creation, deletion, or modification of critical data, as well as unauthorized access to critical or all accessible data.

MitigationApply Oracle Critical Patch Update for FLEXCUBE Universal Banking (versions 12.1-12.4, 14.0-14.3, 14.5). As an immediate compensating control, restrict network access to the banking application to trusted users only and review low-privileged user permissions.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed Flexcube Universal Banking version
    Access the Oracle Flexcube administration console or check version information files in the application installation directory. Common paths include $FLEXCUBE_HOME/versions or look for version.info files. The version is also sometimes displayed on the login page footer or in system information pages accessible to administrators.
    Affected if The installed version matches: >= 12.1.0 and <= 12.4.0; OR >= 14.0.0 and <= 14.3.0; OR exactly 14.5.0
  2. Confirm HTTP web interface is accessible
    Attempt to access the Flexcube Universal Banking login page via HTTP/HTTPS from a network location. Typical URLs follow patterns like https://hostname/fcubs/login or /flexcube/login. Check if the application responds on standard web ports (80, 443, 8080, 8443).
    Affected if The web interface responds to HTTP requests and is reachable over the network, indicating the attack surface is exposed
  3. Verify presence of low-privileged user accounts
    Review user accounts in the Flexcube user management module. Log into the administrator console and examine the user list. Check for users with roles such as 'maker', 'viewer', 'operator', or other non-administrative roles that have limited privileges but can log in via the web interface.
    Affected if There are user accounts with limited (non-admin) privileges who can authenticate through the web interface, creating the attack vector described

The environment is affected if the installed Oracle Flexcube Universal Banking version falls within 12.1.0-12.4.0, 14.0.0-14.3.0, or 14.5.0 AND the HTTP web interface is network-accessible AND low-privileged user accounts exist in the system.
