Netgear has fixed a serious vulnerability affecting Wi-Fi routers and advised customers to update the software on their devices as soon as possible.

The buffer overflow vulnerability before authentication affects several models of Wireless AC Nighthawk, Wireless AX Nighthawk (WiFi 6) and Wireless AC routers.

The consequences of successful operation can range from failures after a denial of service to RCE if code execution is achieved during an attack.

Attackers can exploit this vulnerability in low-complexity attacks without requiring permissions or user interaction.

NETGEAR stated that it is not responsible for any consequences in the event of failure or untimely implementation of its recommendations to correct the flaw.

In addition, on Wednesday, Netgear urged customers to also fix a second vulnerability that can be used to trigger a denial of service state in attacks targeting its routers.
