Script execution via stored replacement-message markup
Published Dec 6, 2022 · Updated Oct 22, 2024
Stored cross-site scripting in Fortinet FortiOS and FortiProxy allows remote authenticated users to execute script through replacement messages. The replacement-message editor stores attacker-controlled markup without neutralizing executable browser content and later renders it to another administrator. A highly privileged administrator must save the payload and another user must view the affected message, enabling script execution in that user's browser session.
