How the attack works simplified

  1. 1Remote attackerNo login or credentials needed
  2. 2RMI connectionReaches the exposed RMI interface over the network
  3. 3Console flawRepository Explorer component is exploitable
  4. 4Product takeoverAttacker gains full control of the product
  5. ResultAttacker takes over Oracle Data Integrator

What happened

A flaw in the Console / Repository Explorer component of Oracle Data Integrator lets an unauthenticated attacker with network access reach it over RMI and fully compromise the product.

Why it is dangerous: A full takeover gives the attacker access to confidential data, the ability to alter it, and the power to shut the service down. Any organization running Oracle Data Integrator where RMI is reachable from a network is at 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 its RMI interface reachable over the network.

Oracle Data Integrator 12.2.1.4.0; Oracle Data Integrator 14.1.2.0.0

What to do

  1. Check whether Oracle Data Integrator 12.2.1.4.0 or 14.1.2.0.0 is installed and whether its RMI port is reachable from untrusted networks
  2. Restrict network access to the Oracle Data Integrator RMI interface to only trusted hosts
  3. Check Oracle's security advisory for a patch and apply it as soon as it is available
