What happened

Oracle SOA Suite (Fabric Layer component, part of Oracle Fusion Middleware) contains a flaw that lets an unauthenticated attacker send HTTP requests and fully compromise the product.

Why it is dangerous: An attacker who reaches the service can take over the whole system, affecting confidentiality, integrity, and availability. Organizations that expose SOA Suite to networks, including the internet, are most at risk.

Are you affected?

You are affected if you run Oracle SOA Suite 12.2.1.4.0 or 14.1.2.0.0 and its HTTP interface is reachable from networks that untrusted users can access.

Oracle SOA Suite 12.2.1.4.0; Oracle SOA Suite 14.1.2.0.0 (component: Fabric Layer)

What to do

  1. Check whether your Oracle SOA Suite version is 12.2.1.4.0 or 14.1.2.0.0
  2. Restrict network access to SOA Suite HTTP endpoints so only trusted systems can reach them
  3. Apply the Oracle Critical Patch Update or vendor fix for this advisory as soon as it is available
