CVE-2020-9288Network attack vector

Stored script execution via profile input

Published Jun 22, 2020 · Updated Oct 25, 2024

Stored XSS in Fortinet FortiWLC 8.5.1 allows remote authenticated users to execute script in another user's browser via crafted profiles. The ESS and RADIUS profile handlers store attacker-controlled input without neutralizing it before later web-page rendering. An authenticated account must save a crafted profile, and execution requires another user to view the affected profile page; resulting access is limited to that user's browser context.
