CVE-2023-33793Public exploitNetwork attack vector

Stored script execution via unescaped panel names

Published May 24, 2023 · Updated Aug 2, 2024

Stored XSS in NetBox 3.5.1 allows remote authenticated users to execute scripts in another user's browser through a power-panel name. The Power Panels name field accepts an HTML event-handler payload that is stored and later rendered as active content when a power feed selects the panel. A user needs permission to create a power panel, and a second user must open the power-feed selection view; NetBox maintainers dispute treating the duplicated object-field reports as separate CVEs.
