Technical details
- Root cause: A flaw in the Content Acquisition System component of Oracle Commerce Guided Search / Experience Manager that permits unauthorized operations without requiring authentication.
- Trigger conditions: No privileges or user interaction are required; the attacker only needs network access to the exposed HTTP service.
- Attack vector: Network (AV:N), low attack complexity (AC:L), exploitable over HTTP.
- Impact: No confidentiality impact, but high integrity impact (unauthorized creation, modification, or deletion of data) and high availability impact (denial of service via hangs or crashes).
