AI Analysis
Technical Summary
OpenCTI-Platform opencti versions before 6.9.7 contain an improper access control vulnerability (CWE-284) where organization administrators can escalate their privileges by adding users from other organizations with higher privileges into their own organization. This occurs because the access control list (ACL) on the userEdit relationAdd operation is incorrectly implemented, allowing unauthorized privilege escalation. The vulnerability is addressed and fixed in version 6.9.7.
Potential Impact
An attacker with organization admin privileges can escalate their access rights by incorporating users from other organizations who have higher privileges, potentially gaining unauthorized control and access to sensitive information or functionality within the platform. This impacts confidentiality, integrity, and availability as indicated by the CVSS vector (C:H/I:H/A:H).
Mitigation Recommendations
Upgrade OpenCTI-Platform opencti to version 6.9.7 or later, where this improper access control vulnerability has been fixed. No other mitigation or temporary workaround is indicated in the available data.
