What happened

A flaw in the Fabric Layer component of Oracle SOA Suite allows unauthenticated network attackers to reach it via the T3 and IIOP protocols and fully take over the product, with a scope change that can impact other products.

Why it is dangerous: Successful exploitation gives the attacker full control of the affected server and may spread impact to connected products, which is a serious risk for any organization running exposed SOA middleware.

Are you affected?

You are affected if you run Oracle SOA Suite 12.2.1.4.0 or 14.1.2.0.0 with the T3 or IIOP protocols reachable over the network.

Oracle SOA Suite 12.2.1.4.0; Oracle SOA Suite 14.1.2.0.0 (Oracle Fusion Middleware, Fabric Layer component)

What to do

  1. Check whether Oracle SOA Suite 12.2.1.4.0 or 14.1.2.0.0 is installed in your environment
  2. Restrict network access to T3 and IIOP ports so only trusted hosts can reach them
  3. Apply the official Oracle Critical Patch Update or vendor fix for this advisory as soon as it is available
