CVE-2019-19225Public exploitNetwork attack vector

Unauthenticated DNS modification via crafted POST request

Published Mar 4, 2020 · Updated Aug 5, 2024

Missing authentication in the D-Link DSL-2680 web interface on firmware EU_1.03 allows remote attackers to change DNS servers. The Forms/dns_1 handler accepts a crafted POST request and applies DNS configuration changes without requiring an authenticated administrator session. Network access to the administration interface is sufficient, and exploitation can redirect the router's DNS resolution without reading data or interrupting service.
