Only systems where Oracle Outside In Technology 8.5.8 runs, typically Oracle Fusion Middleware deployments that parse documents. The attacker needs a local logon to the host, so internet-only exposure is not the main path, but a user processing a crafted file is required. Teams without Oracle Outside In installed can skip it.
