Organisations running Oracle Siebel CRM Cloud Applications in the affected version range. Exposure depends on an attacker having access to the physical or adjacent network segment attached to the hardware that runs the application, so it is mainly a concern for hosts reachable from shared or untrusted network segments. Teams using only Oracle-hosted SaaS with no direct access to the underlying segment can likely skip urgent action, but this is not confirmed by the sources.
