CVE-2017-18852

Unauthorized router access via undisclosed request handling

Published Apr 20, 2020 · Updated Aug 5, 2024

CSRF and authentication bypass in NETGEAR R7300DST, R8300, R8500, and WNDR3400v3 routers allows attackers to access protected functions. NETGEAR has not published the affected request endpoint or the authentication decision that fails. The CSRF path requires victim interaction; MITRE instead scores a local unauthenticated path, and the public records do not reconcile the two reachability models.
