CVE-2024-41591Network attack vector

Script execution via unsanitized content reflection

Published Oct 3, 2024 · Updated Mar 14, 2025

DOM-based reflected XSS in the DrayTek Vigor3910 Web UI through 4.3.2.6 allows remote attackers to execute script via a crafted URL. The doc/hslogp1_link.htm page copies the content query-string parameter directly into the HTML body without sanitization. The victim must open the crafted page, after which the script runs in the router Web UI origin and can read or modify data available to that browser session.
