Description

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. Devices with automatic updates enabled may already have this patch applied. If not, please check the firmware version and update to the latest. Fixed in: RAX30 firmware 1.0.14.108 or later. RAXE300 firmware 1.0.9.82 or later
