CVE-2026-62657

Unauthenticated device takeover

Published Jul 14, 2026 · Updated Jul 14, 2026

Certificate validation in NETGEAR MR70, MS70, RAXE500, and XR1000 firmware allows remote attackers to access and control the device. The code-level certificate-validation operation is undisclosed; NETGEAR identifies only the router certificate-validation process. Exploitation requires an adjacent position, high complexity, and additional prerequisites, but no credentials or user interaction; it permits device-data access and modification without availability impact.
