CVE-2023-45581Network attack vector

Cross-site administration via missing authorization enforcement

Published Feb 15, 2024 · Updated Aug 2, 2024

Improper privilege management in affected Fortinet FortiClient EMS releases allows remote authenticated users to administer other sites. The graphical administrative interface accepts crafted HTTP or HTTPS requests from a site-scoped Super Admin without enforcing the site's authorization boundary. Exploitation requires multitenancy and site Super Admin privileges and permits global operations affecting other sites.
