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 Oracle Flexcube Universal Banking installationLocate the Flexcube installation directory or check system inventory for Oracle Flexcube Universal Banking software. Look for application logs, configuration files, or deployment artifacts that confirm this product is installed.Affected if The software is present on the system
-
Determine installed versionCheck the version of Oracle Flexcube Universal Banking by examining version files, About dialogs, or using the product's administrative interface. Common locations include installation directories, configuration files, or the web application's login page footer.Affected if The installed version is 12.3.0 OR falls between 14.0.0 and 14.4.0 (inclusive)
-
Verify web interface accessibilityDetermine if the Flexcube web interface is network-accessible by testing HTTP/HTTPS connectivity to the application's URLs. Check firewall rules, reverse proxy configurations, and network segmentation settings.Affected if The web interface is reachable from untrusted networks (AV:N in CVSS vector)
-
Assess account privilegesReview user accounts configured in the Flexcube system. Determine whether low-privileged accounts exist that have network access to the application.Affected if Low-privileged user accounts with HTTP access to the application are present
You are affected if Oracle Flexcube Universal Banking versions 12.3.0 or 14.0.0-14.4.0 are installed and the web interface is network-accessible to low-privileged 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 dataApply Oracle Critical Patch Updates for affected versions (12.3.0, 14.0.0-14.4.0). Implement network access controls to restrict web interface exposure and ensure least-privilege access controls are enforced.
