Vulnerability in the Oracle WebCenter Sites product of Oracle Fusion Middleware (component: Advanced UI). The supported version that is affected is 12.2.1.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebCenter Sites. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle WebCenter Sites, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle WebCenter Sites accessible data. CVSS 3.0 Base Score 7.4 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N).

Security readout for executives and security teams

Plain-English summary

Oracle WebCenter Sites 12.2.1.3.0 has a high-severity issue that can expose critical data. An unauthenticated attacker can reach it over HTTP, but a separate person must interact for the attack to succeed. The main business risk is confidentiality loss, not system outage.

Executive priority

Treat as a high-priority confidentiality risk for any WebCenter Sites deployment. Escalate fastest if the service is externally reachable or handles sensitive customer, publishing, or operational content.

Technical view

The vulnerable component is Oracle WebCenter Sites Advanced UI in Fusion Middleware 12.2.1.3.0. CVSS 3.0 is 7.4: network exploitable, low complexity, no privileges required, user interaction required, changed scope, high confidentiality impact, no integrity or availability impact stated.

Likely exposure

Exposure is most likely where Oracle WebCenter Sites 12.2.1.3.0 is reachable over HTTP by untrusted networks or users. The source bundle names only this supported version and does not identify other affected versions.

Exploitation context

The bundle does not show CISA KEV listing or other evidence of active exploitation. Oracle states exploitation is easy over HTTP by an unauthenticated attacker, but requires human interaction from someone other than the attacker.

Researcher notes

Evidence is limited to Oracle and CVE records. No CWE, exploit details, or affected CPEs are provided in the bundle. Avoid expanding affected scope beyond Oracle WebCenter Sites 12.2.1.3.0 without vendor confirmation.

Mitigation direction

  • Review Oracle's April 2020 Critical Patch Update guidance for WebCenter Sites.
  • Prioritize remediation for internet-accessible or partner-accessible WebCenter Sites deployments.
  • Restrict HTTP access to trusted networks until vendor guidance is applied.
  • Ensure users who access Advanced UI are aware of interaction-based attack risk.
  • Check Oracle guidance before assuming unsupported versions are safe or unaffected.

Validation and detection

  • Inventory Oracle WebCenter Sites deployments and confirm version 12.2.1.3.0 presence.
  • Identify whether WebCenter Sites is reachable over HTTP from untrusted networks.
  • Confirm whether Oracle April 2020 CPU guidance has been applied.
  • Review access logs for unusual WebCenter Sites Advanced UI activity.
  • Document any compensating access restrictions pending vendor-guided remediation.
