Stored XSS via unescaped interface names
Published Jul 9, 2024 · Updated Aug 2, 2024
Stored XSS in NetBox 4.0.3 allows remote authenticated users to execute scripts in another user's browser via an interface name. The interface edit handler stores the crafted Name value, and the web interface later renders that value without neutralizing executable HTML or JavaScript. Exploitation requires permission to edit an interface and a second user to view the affected content, exposing that browser session to attacker-controlled actions.
