Improper certificate validation in firmware update logic in NETGEAR RAX30 (Nighthawk AX5 5-Stream AX2400 WiFi 6 Router) and RAXE300 (Nighthawk AXE7800 Tri-Band WiFi 6E Router) allows attackers with the ability to intercept and tamper traffic destined to the device to execute arbitrary commands on the device.
