CVE-2023-22638Network attack vector

Authenticated script execution via crafted GET requests

Published Feb 16, 2023 · Updated Oct 23, 2024

Cross-site scripting in affected FortiNAC 8.x and 9.x releases allows remote authenticated users to run script through crafted HTTP GET requests. Multiple stored and reflected paths pass crafted GET input into generated GUI pages without sufficient neutralization; Fortinet does not name the endpoints or parameters. Exploitation requires authenticated access and victim interaction, and successful script execution operates with the victim's browser privileges against the management interface.
