CVE-2021-30003Network attack vector

Stored script execution via unneutralized URL filter input

Published Apr 2, 2021 · Updated Aug 3, 2024

Stored XSS in the Nokia G-120W-F 3FE46606AGAB91 administration interface allows remote authenticated users to execute script in a user's browser. The urlfilter.cgi add action stores the url_address value and later renders it without neutralizing script-capable input. Administrator privileges are required to plant the payload, and another user must view the affected interface; impact is limited to that browser context.
