Stored XSS in TOTOLINK A3002RU 2.1.1-B20230720.1011 allows remote authenticated users to execute scripts through MAC-filter comments. The router stores the Comment value and renders it in the Firewall MAC Filtering page without neutralizing script markup. Administrative access is required to save the comment, and another user must open the affected page; execution remains inside that user's browser session.
