What happened
A critical flaw in the Fabric Layer component of Oracle SOA Suite (Oracle Fusion Middleware) allows unauthenticated remote attacks over HTTP, resulting in full takeover of the product.
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 an attacker could use.
Oracle SOA Suite 12.2.1.4.0; Oracle SOA Suite 14.1.2.0.0 (Fabric Layer component)
What to do
- Check whether your Oracle SOA Suite version is 12.2.1.4.0 or 14.1.2.0.0
- Restrict network access to SOA Suite HTTP endpoints so only trusted systems can reach them
- Apply the official Oracle Critical Patch Update or vendor fix as soon as it is available for your version
- Review logs for unexpected HTTP requests to SOA Suite endpoints
