CVE-2022-30326Public exploitNetwork attack vector

Web-interface page crash via stored XSS

Published Jun 16, 2022 · Updated Aug 3, 2024

Stored XSS in the TRENDnet TEW-831DR 1.0 601.130.1.1356 web interface allows remote authenticated users to crash its main page. The pre-shared-key field stores attacker-supplied script without proper validation or output encoding, and the basic.config and 5G home.htm pages execute it when rendered. Management credentials are required to plant the payload, and a user must later load an affected page; the demonstrated consequence is a page crash and popup.
