What happened

An unauthenticated HTTP-reachable flaw in the Console / Repository Explorer component of Oracle Data Integrator allows full compromise of the product.

Why it is dangerous: Successful attacks can result in complete takeover of Oracle Data Integrator, affecting confidentiality, integrity, and availability. Organizations running exposed ETL/data integration servers are at highest risk.

Are you affected?

You are affected if you run Oracle Data Integrator 12.2.1.4.0 or 14.1.2.0.0 with the Console / Repository Explorer reachable over the network.

Oracle Data Integrator 12.2.1.4.0; Oracle Data Integrator 14.1.2.0.0

What to do

  1. Restrict network access to the Oracle Data Integrator Console and Repository Explorer to trusted hosts only
  2. Check Oracle's Security Alert advisory and apply the official patch for your affected version as soon as it is available
  3. Review logs for unexpected HTTP requests to the Console and Repository Explorer
