CVE-2022-41330Network attack vector

Script execution via crafted administrative GET requests

Published Apr 11, 2023 · Updated Oct 23, 2024

Cross-site scripting in the FortiOS and FortiProxy administrative interface allows remote attackers to execute script via crafted HTTP GET requests. Fortinet identifies the GUI as the affected component but has not disclosed which GET parameter is reflected or how the interface fails to neutralize it. Exploitation requires an administrative-interface user to load the crafted request, allowing attacker-supplied script to run in that user's browser context.
