DrayTek Vigor2925 firmware can run unwanted code on login page

CVE-2019-16533 · published 7 years ago
Summary

The login page in firmware version 3.8.4.3 for DrayTek Vigor2925 routers does not properly restrict who can access it, allowing an attacker to inject malicious script. This could let a hacker display fake messages or steal information from anyone who visits the page. Because the product is no longer supported, the safest step is to replace the router with a current model or use a web‑filtering solution to block the malicious page.
