How the attack works simplified

  1. 1Remote attackerNo login or account needed
  2. 2HTTP requestSent over the network to SOA Suite
  3. 3Fabric Layer flawRequest is processed without authentication
  4. 4Data accessedConfidential data can be read
  5. 5Records alteredSome data can be changed or deleted
  6. ResultAttacker gains data access in SOA Suite

What happened

A critical flaw in the Fabric Layer component of Oracle SOA Suite can be exploited over HTTP without authentication, with a scope change that can affect other products.

Why it is dangerous: Attackers can reach confidential data and alter some records, and because the scope changes, damage can spread to other connected products. Organizations exposing SOA Suite to a network 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 with its HTTP interface reachable from a network.

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

What to do

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