AI-suggested

European organizations should immediately upgrade OpenCTI installations to version 6.8.1 or later to apply the official patch that enforces proper authorization checks. Until the upgrade is possible, implement strict access control policies limiting who can authenticate and access the GraphQL API, especially restricting deletion permissions to trusted administrators. Employ network segmentation and firewall rules to restrict access to the OpenCTI API endpoints to authorized internal users only. Enable detailed logging and monitoring of GraphQL mutation requests to detect unusual deletion activities or attempts to access UUIDs not owned by the requester. Conduct regular audits of user permissions and workspace ownership to identify and remediate any misconfigurations. Consider implementing multi-factor authentication (MFA) to reduce the risk of compromised credentials being used to exploit this vulnerability. Finally, develop and test backup and recovery procedures for OpenCTI data to quickly restore deleted workspaces if exploitation occurs.

Description

OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior to version 6.8.1, the GraphQL mutation "WorkspacePopoverDeletionMutation" allows users to delete workspace-related objects such as dashboards and investigation cases. However, the mutation lacks proper authorization checks to verify ownership of the targeted resources. An attacker can exploit this by supplying an active UUID of another user. Since the API does not validate whether the requester owns the resource, the mutation executes successfully, resulting in unauthorized deletion of the entire workspace. Version 6.8.1 fixes the issue.
