CVE-2025-3996Public exploitNetwork attack vector

Stored script execution via unneutralized filter comments

Published Apr 28, 2025 · Updated Apr 28, 2025

Stored cross-site scripting in the MAC Filtering page of TOTOLINK N150RT 3.4.0-B20190525 allows remote authenticated users to run script. /home.htm stores the unneutralized Comment field and later renders it in the MAC Filtering interface, causing a visiting browser to execute attacker-supplied markup. Administrative privileges are required to submit the payload, and a user must view the affected page; successful exploitation alters content in that browser context.
