Stored script execution via unneutralized configuration fields
Published May 6, 2025 · Updated May 6, 2025
Stored cross-site scripting in W&T network appliances allows remote authenticated users to run scripts through configuration fields. The interface stores crafted HTML or script content in several fields, including the page title, then renders it without adequate neutralization. Exploitation requires low-privileged configuration access and a victim to view the affected page, enabling limited browser-context data access or page modification.
