Analysis

AI-generated

Technical impact

The vulnerability resides in the Security Framework of Oracle WebCenter Portal and allows a low‑privileged attacker with network access over HTTP to compromise the application, exploiting missing authentication enforcement (CWE-284). The flaw can be exploited easily and leads to full takeover of the portal, affecting confidentiality, integrity, and availability. The CVSS 3.1 base score of 9.9 reflects a high‑severity risk with abundant impact across all security categories.

Affected Systems

Affected are Oracle WebCenter Portal versions 12.2.1.4.0 and 14.1.2.0.0, delivered by Oracle Corporation as part of its Fusion Middleware suite.

Risk and Exploitability

The CVSS score of 9.9 indicates critical severity, while the EPSS score of less than 1 % suggests that exploitation is not common yet; however, the low privilege requirement and availability of network‑based HTTP access make the attack surface broad. The vulnerability is not listed in CISA's KEV catalog, so no evidence of widespread exploitation exists at present, yet the potential for scope change means other products could be affected if the portal is compromised. Attackers would likely use the exposed HTTP endpoint to push malicious code or execute privileged actions, taking over the portal and possibly other connected systems.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest Oracle WebCenter Portal security patch or upgrade to a version that includes the fix.
  • Restrict HTTP access to IP ranges and enforce strong authentication for all users.
  • Monitor web application logs for anomalous activity and block malicious IPs. Optionally, disable publicly exposed Security Framework endpoints if not required.
