AI Analysis

Impact

A flaw in Oracle WebCenter Sites allows an unauthenticated attacker with network access over HTTP to compromise the system. Successful exploitation can lead to unauthorized reading of critical data, as well as inserting, updating, or deleting data, and can induce a partial denial of service. The primary weakness is improper access control, as reflected in the CVSS vector of AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L.

Affected Systems

Oracle WebCenter Sites product versions 12.2.1.4.0 and 14.1.2.0.0 are affected. No other vendors or product families are listed as impacted.

Risk and Exploitability

The vulnerability carries a CVSS 3.1 base score of 8.6, indicating high severity. The EPSS score of less than 1% indicates that exploitation probability is currently very low, and the vulnerability is not listed in the CISA KEV catalog. The CVSS vector shows a remote attack over an insecure HTTP protocol with no authentication required, meaning any network user could attempt to abuse the flaw. Because it can lead to unauthorized data access, modification, and partial service disruption, the risk remains significant for organizations running these versions.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the latest Oracle WebCenter Sites patch for versions 12.2.1.4.0 and 14.1.2.0.0 as released in the Oracle security alert referenced above.
  • If patching is not immediately possible, restrict HTTP access to the application by placing it behind a firewall or proxy that limits inbound traffic to trusted IP addresses.
  • Audit and harden the site’s authentication and authorization configuration, ensuring that all data access requires proper credentials and privileges.
  • Monitor logs for suspicious activity such as repeated unauthenticated requests and enforce rate limiting to mitigate potential denial of service.
  • Keep the system updated with future security releases and review Oracle’s advisories for additional mitigations.
