Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in the Oracle FLEXCUBE Universal Banking product of Oracle Financial Services Applications (component: Infrastructure). Supported versions that are affected are 12.1-12.4, 14.0-14.3 and 14.5. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle FLEXCUBE Universal Banking. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle FLEXCUBE Universal Banking accessible data as well as unauthorized access to critical data or complete access to all Oracle FLEXCUBE Universal Banking accessible data. CVSS 3.1 Base Score 6.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:N).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Vulnerability in Oracle FLEXCUBE Universal Banking Infrastructure component allows low privileged attackers with network access via HTTP to modify or access critical data. Successful exploitation requires human interaction (UI:R), indicating a social engineering or click-based attack vector.

MitigationApply Oracle Critical Patch Update for FLEXCUBE Universal Banking. Restrict network access to the application and implement additional user awareness training since human interaction is required for exploitation.

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 Oracle FLEXCUBE Universal Banking installation version
    Locate the Oracle FLEXCUBE installation directory and check for version information in VERSION.txt, manifest files, or query the Oracle Inventory (oratab or oraInventory) for the Flexcube component version.
    Affected if Installed version matches >= 12.1.0 AND <= 12.4.0, OR >= 14.0.0 AND <= 14.3.0, OR = 14.5.0
  2. Confirm web application is network-accessible
    Verify the Oracle FLEXCUBE Universal Banking web interface (HTTP/HTTPS endpoints) is exposed to the network and accessible to low privileged users.
    Affected if The FLEXCUBE web interface is reachable from the network by users with low privileges
  3. Check if end-user browser access is enabled
    Determine whether direct browser-based access to the FLEXCUBE application is enabled for end users, as this is required for the human interaction (UI:R) attack vector.
    Affected if End users have direct interactive access to the web interface

The environment is affected if Oracle FLEXCUBE Universal Banking version is 12.1.0-12.4.0, 14.0.0-14.3.0, or exactly 14.5.0, and the web application is accessible to low privileged users who can be socially engineered.

Upgrade available Upgrade to a release after 14.3.0
Interim mitigation

Apply Oracle Critical Patch Update for FLEXCUBE Universal Banking. Restrict network access to the application and implement additional user awareness training since human interaction is required for exploitation.

Recommended fix High confidence

Upgrade to version 14.6.0 or later (or the latest supported version within your major release train)

  1. Check the Oracle Critical Patch Update for July 2022 (or the nearest subsequent CPU) on oracle.com for CVE-2022-21577
  2. Download and apply the relevant Oracle FLEXCUBE Universal Banking patch for your version from Oracle Support
  3. After patching, verify the Infrastructure component has been updated by checking the version or consulting Oracle documentation
  4. Test the patch in a non-production environment before deploying to production
  5. Coordinate the patch deployment with the appropriate change management process as the fix requires human interaction to complete
Caveat Review Oracle's upgrade guide for your specific version transition; major version upgrades may require testing of custom integrations
