What happened

Oracle Mobile Field Service, part of Oracle E-Business Suite, has a critical flaw in its Internal Operations component that lets an unauthenticated attacker send HTTP requests to compromise the product.

Why it is dangerous: Successful attacks can expose critical business data or all data the service can access, and can cause a hang or repeated crash (denial of service). Organizations running this service with network exposure are at risk.

Are you affected?

You are affected if you run Oracle Mobile Field Service in Oracle E-Business Suite versions 12.2.3 through 12.2.15, and it is reachable over the network via HTTP.

Oracle Mobile Field Service (Oracle E-Business Suite, component Internal Operations), supported versions 12.2.3-12.2.15

What to do

  1. Check whether Oracle Mobile Field Service in your Oracle E-Business Suite is running a version from 12.2.3 to 12.2.15
  2. Apply the patch or update from Oracle's Security Alert or the GitHub advisory GHSA-266p-rwfv-v576 as soon as it is available
  3. Limit network access to the service to trusted users and networks until patched
