Who should care

Organizations running Oracle FLEXCUBE Universal Banking, especially teams responsible for internet-facing application access, patch management, and security monitoring.

Technical summary

NVD classifies the issue with CVSS v3.0 vector CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, indicating a network-reachable vulnerability that requires no privileges or user interaction and primarily impacts confidentiality. The reported weakness is CWE-284. The supplied description states that an unauthenticated attacker with HTTP network access can compromise Oracle FLEXCUBE Universal Banking by obtaining unauthorized read access to a subset of accessible data.

Defensive priority

Medium. The issue is unauthenticated and network-reachable, but the reported impact is limited to confidentiality and a subset of accessible data. Prioritize if the affected FLEXCUBE versions are exposed to untrusted networks or handle sensitive banking data.

Recommended defensive actions

  • Identify Oracle FLEXCUBE Universal Banking deployments and confirm whether any affected versions 11.3.0, 11.4.0, 12.0.1, 12.0.2, 12.0.3, 12.1.0, or 12.2.0 are in use.
  • Review Oracle's CPU January 2017 advisory and applicable vendor guidance for remediation or patches.
  • Restrict network exposure of FLEXCUBE interfaces, especially HTTP-accessible endpoints, to trusted administrative and application networks.
  • Monitor for anomalous access to FLEXCUBE data and review logs for unauthorized read activity.
  • If immediate patching is not possible, apply compensating controls such as segmentation and access restrictions around the affected service.

Evidence notes

All core claims are taken from the supplied NVD record and CVE metadata: public disclosure date 2017-01-27, modified date 2026-05-13, affected versions, network/HTTP attack path, unauthenticated access requirement, and confidentiality-only CVSS impact.
