CVE-2023-34565Public exploitNetwork attack vector

Stored script execution via Wireless LAN group name

Published Jun 14, 2023 · Updated Aug 2, 2024

Stored cross-site scripting in NetBox 3.5.1 allows remote authenticated users to execute arbitrary script in another user's browser. The Wireless LAN group Name field accepts an image element with an onerror handler, stores it, and later renders it without neutralizing executable markup. A low-privileged authenticated account must create the group, and another user must open the affected Wireless LAN edit workflow; successful exploitation runs script with that user's web-session authority.
