Unauthorized JSP calls via improper access controls

Published Jun 13, 2023 · Updated Oct 22, 2024

Improper access control in affected Fortinet FortiNAC releases allows remote authenticated users to invoke unauthorized JSP endpoints. The administrative interface accepts crafted HTTP requests for JSP calls that the authenticated account is not authorized to perform; Fortinet has not disclosed the responsible handler or missing authorization check. Administrative-interface credentials are required, and the specific actions and resulting confidentiality, integrity, or availability effects are undisclosed.
