AI Analysis

Impact

Oracle WebCenter Sites is vulnerable to a remote code execution flaw that allows an attacker with low privileges and network access over HTTP to take over the system. The flaw is easily exploitable and results in a complete compromise of confidentiality, integrity, and availability by allowing the attacker to execute arbitrary code on the server. The impact is a full takeover of the WebCenter Sites application.

Affected Systems

The affected product is Oracle WebCenter Sites from Oracle Fusion Middleware. Versions 12.2.1.4.0 and 14.1.2.0.0 are impacted; no other P/E versions are listed as affected.

Risk and Exploitability

The vulnerability carries a CVSS 3.1 Base Score of 9.9 and has a low exploit probability of less than 1% according to EPSS, but it is not listed in the CISA KEV catalog. The attack vector is network‑based via HTTP, with the attacker only needing low privileges and no user interaction. Because the vector includes a scope change, successful exploitation could affect additional components beyond WebCenter Sites, amplifying the enterprise risk. Given the high damage potential, the risk level remains critical even though real‑world exploitation is currently unlikely.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the Oracle patch or upgrade to a non‑affected WebCenter Sites release as specified in the official security advisory.
  • Configure firewall rules or network segmentation to restrict HTTP access to WebCenter Sites only from trusted hosts or internal networks.
  • Enforce strict authentication and limit administrative or privileged API access to authorized users, ensuring that no anonymous or low‑privileged users can reach exposed endpoints.
