CVE-2024-32334Public exploitNetwork attack vector

Stored script execution via unescaped filter comments

Published Apr 18, 2024 · Updated Aug 2, 2024

Stored cross-site scripting in TOTOLINK N300RT 2.1.8-B20201030.1539 allows remote authenticated users to execute script in another user's browser. The Comment field stores an SVG onload payload without neutralizing it, and the management page later renders and executes the stored JavaScript. A low-privileged authenticated user must save the payload and another user must visit the page, placing that user's in-origin data and actions at risk.
